python: fix return value of emptiness_check_instantiator
* wrap/python/spot.i: Fix typemap for
emptiness_check_instantiator::construct. The previous code used
to turn (None, "error") into simply ("error").
* wrap/python/ajax/spot.in: Fix handling or errors when
instantiating emptiness checks.
2012-02-25 Alexandre Duret-Lutz <adl@lrde.epita.fr>
* NEWS: Summarize recent changes.
2012-02-25 Alexandre Duret-Lutz <adl@lrde.epita.fr>
Make all python code compatible with Python 2.x and Python 3.x.
* wrap/python/buddy.i (__le__, __lt__, __eq__, __ne__, __ge__
__gt__): New operators for bdd.
* wrap/python/spot.i (__le__, __lt__, __eq__, __ne__, __ge__
__gt__, __hash__): New operators for formula.
(nl_cout, nl_cerr): New functions.
* wrap/python/tests/bddnqueen.py,
wrap/python/tests/interdep.py, wrap/python/tests/ltl2tgba.py,
wrap/python/tests/ltlparse.py, wrap/python/tests/ltlsimple.py,
wrap/python/tests/minato.py, wrap/python/tests/modgray.py: Adjust
to the new print syntax by using sys.output.write() or nl_cout()
instead.
* wrap/python/tests/optionmap.py: Remove all print calls.
* wrap/python/ajax/spot.in: Massive adjustments in order to work
with both Python 2 and 3. In python 3, reopening stdout as
unbuffered requires it to be open as binary, which in turns
requires any string output to be encoded manually. BaseHTTPServer
and CGIHTTPServer have been merged into http.server, so we have
to try two different import syntaxes. execfile no longer exists,
so it has to be emulated.
This also fixes two bugs where the script would segfault on
empty input, or when calling Tau03 on automata with less then
one acceptance conditions.
2012-02-24 Alexandre Duret-Lutz <adl@lrde.epita.fr>
Fix computation of PYTHONINC for Python 3.
* m4/pypath.m4: The print syntax changed in Python 3, so use
sys.stdout.write for compatibility with all versions.
2012-02-04 Alexandre Duret-Lutz <adl@lrde.epita.fr>
* HACKING: Minor updates and corrections.
2012-02-15 Alexandre Duret-Lutz <adl@lrde.epita.fr>
Fix a race condition on the CGI script.
* wrap/python/ajax/spot.in: Create all cache files in a temporary
directory, and only rename this directory at the end. This way if
two processes are processing the same request, they won't attempt
to populate the same directory (and only one of the first of two
renames will succeed, but that is OK).
2012-01-24 Alexandre Duret-Lutz <adl@lrde.epita.fr>
Fix a segfault reported by Etienne Renault using dve2check.
* src/misc/intvcmp2.cc (stream_compression_base::run): Fix a case
where the "id" of the compression to use would be miscalculated,
causing wrong values to be encoded.
* src/tgbatest/intvcmp2.cc: Add this particular test case.

Implement create_sates().
(tgba_tba_proxy, tgba_sba_proxy, tgba_tba_proxy_succ_iterator):
Adjust state construction to call create_state().
2012-01-17 Alexandre Duret-Lutz <adl@lrde.epita.fr>
Minor speedups in tgba_safra_complement().
* src/tgba/tgbasafracomplement.cc (safra_tree:succ_create): Do not
lookup *i twice, and do not copy it->second.
(safra_tree::normalize_siblings): Do not lookup *node_it before
insertion.

Fix position of the Send button with WebKit.
* wrap/python/ajax/css/ltl2tgba.css: Fix position of the "Send"
button with WebKit. The folding arrow icon had a vertical border
that overlapped with the next line.
2012-01-17 Alexandre Duret-Lutz <adl@lrde.epita.fr>
* wrap/python/ajax/spot.py: Add a required "None" second
argument to utime().
2012-01-17 Alexandre Duret-Lutz <adl@lrde.epita.fr>
minimize_wdba() failed to fully minimize some automata.
* src/tgbaalgos/minimize.cc (minimize_wdba): Fix the Löding
algorithm to use colors. The previous implementation was an
incorrect approximation.
* src/tgbatest/wdba2.test: New file showing two equivalent
formulas that were minimized in automata with different sizes.
* src/tgbatest/Makefile.am: Add it.

* NEWS: Update with recent fixes.
2012-01-13 Alexandre Duret-Lutz <adl@lrde.epita.fr>
Fix a 'make check' failure when valgrind is not installed.

incorrectly trying to run valgrind even when valgrind is not
installed.
* src/kripketest/kripke.test: Simplify and use run().
2012-01-12 Alexandre Duret-Lutz <adl@lrde.epita.fr>

2012-01-06 Alexandre Duret-Lutz <adl@lrde.epita.fr>
* lrde-upload.sh: Retrieve the package version from configure.ac.
2012-01-05 Ala-Eddine Ben-Salem <ala@lrde.epita.fr>
Fix detection of the last iteration of minimize_dfa().
* src/tgbaalgos/minimize.cc (minimize_dfa): Fix detection of the
last iteration. An extra iteration case could be missed in case
where a split generates only singletons, and yet predecessor
classes need to be refined.
2012-01-05 Alexandre Duret-Lutz <adl@lrde.epita.fr>
Fix computation of length of LTL formulas.
* src/ltlvisit/length.cc: Fix computation for ltl::multop
operator. "a&b&c" was reported with length 3, ignoring the
"&" operators, because of a typo.
* src/ltlvisit/length.hh: Fix description to correctly
reflect this change intended since 2010-01-22.

2011-12-16 Alexandre Duret-Lutz <adl@lrde.epita.fr>
Perform WDBA minimization before degeneralization.
There is no point in degeneralizing an automaton if it can be WDBA
minimized. Doing so will only augment the number of states and
slow down the powerset construction used by the WDBA minimization.
* src/tgbatest/babiak.test: New file. It includes 5 formulae
which Tomáš Babiak reported Spot 0.7.1 would take over one hour to
translate if degeneralization and WDBA minimization were both
requested.
* src/tgbatest/Makefile.am (TESTS): Add it.
* src/tgbatest/ltl2tgba.cc: Do WDBA minimization before
degeneralization. The above formulae are now all translated in a
few seconds.
2011-12-16 Alexandre Duret-Lutz <adl@lrde.epita.fr>
Don't rely on the g++ version to include tr1/unordered_map and co.
The previous setup failed with clang++ 3.0.
* m4/stl.m4: New file.
* configure.ac: Call AC_HEADER_UNORDERED_MAP,
AC_HEADER_TR1_UNORDERED_MAP, and AC_HEADER_EXT_HASH_MAP.
* src/misc/hash.hh: Include _config.h, and used the
SPOT_HAVE_UNORDERED_MAP, SPOT_HAVE_TR1_UNORDERED_MAP,
or SPOT_HAVE_EXT_HASH_MAP defines to decide which
file to include.
2011-12-01 Alexandre Duret-Lutz <adl@lrde.epita.fr>

2011-11-16 Alexandre Duret-Lutz <adl@lrde.epita.fr>
Fully quote guards used by neverclaims.
Especially with should write !(p0) and not !p0, because p0 is
usually #define'd by the user and he may have forgotten to quote
the value of the macro. This issue was discovered by Kristin
Yvonne Rozier and diagnosed by Gerard Holzmann.
* src/tgbaalgos/neverclaim.cc (process_link): Call

(tgba_safra_complement::tgba_safra_complement)
(tgba_safra_complement::succ_iter): Correct the declaration and
use of multiple acceptance conditions.
(state_complement::to_string): Output the L set, not U. The previous
code caused different states to share the same names, causing issues
with the text-based output (state with identical names get merged).

process_link): Remove these empty methods. The default
implementations are empty too, and process_link had the
wrong prototype.

(start, end, process_link): Likewise.
2011-08-27 Alexandre Duret-Lutz <adl@lrde.epita.fr>
Improve SCC simplification by removing implied acceptance conditions.
Spot 0.7.1 used to need 190 acceptance conditions to translate the
188 literature formulae. With this patch we are down to 185.
That's not an impressive, but there are only ~20 formulae that
require more than 1 acceptance conditions; hence little room for
improvement.

conditions that are always implied by another acceptance
conditions. Previously, we only removed acceptance conditions
that where always present in accepting SCCs.
* src/tgbatest/sccsimpl.test: New file.
* src/tgbatest/Makefile.am (TESTS): Add it.
2011-08-26 Alexandre Duret-Lutz <adl@lrde.epita.fr>
Refine yesterday's change to the degeneralization.
This avoids a small regression on the size of degeneralized
automata of our usual list of literature formulae.
* src/tgba/tgbatba.hh, src/tgba/tgbatba.cc
(tgba_tba_proxy::union_acceptance_conditions_of_original_state):
New method.
* src/tgba/tgbatba.cc (tgba_tba_proxy_succ_iterator): In accepting
states, ignore only the last expected acceptance condition if its
common to all outgoing transitions AND if it is not used by any
outgoing transitions of the destination.
2011-08-25 Alexandre Duret-Lutz <adl@lrde.epita.fr>
Make sure the degeneralization is idempotent (up to renaming of
states).
* src/tgbaalgos/tgbatba.cc: When degeneralizing to SBA, remove the
acceptance conditions that are common to all outgoing transitions
of this state. This helps to make the degeneralization
idempotent.

* src/tgbaalgos/save.c (process_state): Escape quotes in the
name of source and destination states. This fixes a side bug
in the upcoming degenid.test test case.
2011-08-25 Alexandre Duret-Lutz <adl@lrde.epita.fr>
Running `ltl2tgba -R1q -R1t -N` would degeneralize before and
after the simulation-reduction.
Report from Tomáš Babiak <xbabiak@fi.muni.cz>.

2011-04-10 Alexandre Duret-Lutz <adl@lrde.epita.fr>
Always pass --enable-devel or --disable-devel to BuDDy.
* configure.ac: Do not add CXXFLAGS and CFLAGS in ac_configure_args,
it causes problem when using config.cache. Instead ...
* m4/devel.m4: Add --enable-devel or --disable-devel on
ac_configure_args, now that BuDDy understands that.
2011-04-10 Alexandre Duret-Lutz <adl@lrde.epita.fr>

* src/tgbatest/Makefile.am: Add them.
2011-04-09 Alexandre Duret-Lutz <adl@lrde.epita.fr>
Fix two spurious segfaults in test cases for the Python interface.
* wrap/python/tests/setxor.py, wrap/python/tests/bddnqueen.py:
Clean all used bdd variables before calling bdd_done(), so that
bdd_delref() is never called after bdd_done(). In NDEBUG builds,
bdd_delref() does not check whether the BuDDy is running or not,
and calling it after bdd_done() will crash.
2011-04-09 Alexandre Duret-Lutz <adl@lrde.epita.fr>
* HACKING: Add an example for using callgrind.
2011-04-06 Alexandre Duret-Lutz <adl@lrde.epita.fr>

appropriate.
2011-03-31 Alexandre Duret-Lutz <adl@va-et-vient.net>
Cosmetics.
* src/sanity/style.test: Catch some binary operators not
delimited with spaces.
* src/tgbaalgos/bfssteps.cc, src/tgbaalgos/magic.cc,
src/tgbaalgos/reducerun.cc, src/tgbaalgos/se05.cc,
src/tgbaalgos/tau03.cc, src/tgbaalgos/tau03opt.cc: Fix these.
2011-03-31 Alexandre Duret-Lutz <adl@lrde.epita.fr>
Make state_explicit instances persistent objects.
* src/tgba/tgbaexplicit.cc, src/tgba/tgbaexplicit.hh: Merge
state_explicit and tgba_explicit::state. In the past,
state_explicit was a small object encapsulating a pointer to the
persistent tgba_explicit::state; and we used to clone() and
destroy() a lot of state_explicit instance. Now state_explicit is
persistent, and clone() and destroy() have no effects.
* src/tgba/tgbareduce.cc: Adjust, since this inherits from
tgbaexplicit and uses the internals of state_explicit.
* src/tgbatest/reductgba.cc: Fix deletion order for automata.
* src/tgba/tgba.hh (last_support_conditions_input_,
last_support_variables_input_): Make these protected, so
they can be zeroed by tgba_explicit.
2011-03-30 Alexandre Duret-Lutz <adl@lrde.epita.fr>
Remove tgba_reduc::format_state().
* src/tgba/tgbareduc.cc, src/tgba/tgbareduc.hh (format_state):
Remove this useless copy of the tgba_explicit_string::format_state
method.
2011-03-30 Alexandre Duret-Lutz <adl@lrde.epita.fr>
Protect the state destructor.
Client code should always call the destroy() method instead. (It
was introduced in Spot 0.7.)
* src/tgba/state.hh (state::~state): Make it protected.
2011-03-30 Alexandre Duret-Lutz <adl@lrde.epita.fr>
Speedup tgba_product when one of the argument is a Kripke structure.
The gain is not very impressive. The runtime of the first example
in iface/dve2/README (also in dve2check.test) is 15% faster.
* src/tgba/tgbaproduct.hh (tgba_succ_iterator_product): Move ...
* src/tgba/tgbaproduct.cc (tgba_succ_iterator_product,
tgba_succ_iterator_product_common): ... in these two classes.
(tgba_succ_iterator_product_kripke): New class to speedup
successor computation on Kripke structures. We can assume that
all the transitions leaving the same state have the same label.
(tgba_product::tgba_product, tgba_product::succ_iter): Use
tgba_succ_iterator_product_kripke when appropriate.
(tgba_product_init::tgba_product_init): Adjust for the case
where tgba_product did reverse its operands.
2011-03-30 Alexandre Duret-Lutz <adl@lrde.epita.fr>
* iface/dve2/dve2check.cc: Remove stray debug output.
2011-03-30 Alexandre Duret-Lutz <adl@lrde.epita.fr>
* src/tgba/tgbaproduct.hh: Do not include statebdd.hh.
2011-03-29 Alexandre Duret-Lutz <adl@lrde.epita.fr>
Include <cstddef> in python modules to workaround Swig bug.
* wrap/python/spot.i, wrap/python/buddy.i: Include <cstddef>
because Swig 2.0.2 uses ptrdiff_t and does not do the include
itself. In g++ most libstdc++ standard headers have been changed
to no longer include <cstddef> as an implementation detail, so
the difference shows.
2011-03-20 Alexandre Duret-Lutz <adl@lrde.epita.fr>
* THANKS: Add Michael Weber for his help on the DiVinE interface.
2011-03-18 Alexandre Duret-Lutz <adl@lrde.epita.fr>

conditions and successor of the last state, to share
some work between these two function. Add loops on dead
states.

Enable VERBOSE logs for nips, greatspn, and python tests.
* wrap/python/tests/run.in, iface/nips/nipstest/defs.in,
iface/gspn/defs.in: Do not disable VERBOSE when running from "make
check". Since we have started using parallel-check on 2009-08-31,
we should always send verbose output to the log.
2011-02-10 Alexandre Duret-Lutz <adl@lrde.epita.fr>
This should finally fix kv.test and dotty.test on the LIP6 buildfarm.
* src/tgbatest/kv.test, iface/nips/nipstest/dotty.test: Don't rely

* HACKING (Running coverage tests): New section.
2011-02-09 Alexandre Duret-Lutz <adl@lrde.epita.fr>
Previous patch did not work on MacOS X, and I don't have shell
access to that host.
* src/tgbatest/kv.test: Use ${DOT-true} instead of ${DOT-:}. I
don't know, the MacOS shell must be mixing the syntaxes for
${DOT:-} and ${DOT-:}.

Rename is_safety_automaton() as is_guarantee_automaton() and
implement is_safety_mwdba().
Note: I swapped the name of safety and guarantee when I

is_safety_automaton() was only used where is_guarantee_automaton()
would have been correct.

version, we will rewrite tgba_explicit so that it does not
allocate new states (and the destroy() method for explicit state
will do nothing).

2010-12-13 Alexandre Duret-Lutz <adl@lrde.epita.fr>
* NEWS: Update the news about minimization.
2010-11-26 Alexandre Duret-Lutz <adl@lrde.epita.fr>
Speed up wdba.test, it was too slow for our buildfarm.
* src/tgbatest/wdba.test: Speed up execution by running only a
couple of formula with valgrind. Half of those with`-l -R3b' and
the other half with `-f -R3'.
2010-11-26 Alexandre Duret-Lutz <adl@lrde.epita.fr>
* src/tgbatest/ltl2tgba.cc (syntax): Regroup -M, -s, and -S option
under the same heading "automaton conversion".
2010-11-25 Alexandre Duret-Lutz <adl@lrde.epita.fr>
Preliminary support for monitors.

deterministic monitors.
* src/tgbaalgos/minimize.cc (minimize): Take a monitor
argument and adjust the code.
* src/tgbaalgos/minimize.hh (minimize): Document it.
2010-11-25 Alexandre Duret-Lutz <adl@lrde.epita.fr>
"ltl2tgba -Rm -X foo.tgba" would fail.
* src/tgbatest/ltl2tgba.cc (main): Warn if -Rm is used without
knowing the formula whose automaton is minimized.
2010-11-25 Alexandre Duret-Lutz <adl@lrde.epita.fr>
Fix bugs in minimize().
* src/tgbaalgos/minimize.cc (init_sets, minimize): Fix memory
leaks and a usage of the wrong automaton.
* src/tgbatest/wdba.test: Try using -Rm with -R3 or -R3b, and with

2010-04-13 Alexandre Duret-Lutz <adl@lrde.epita.fr>
Fix bugs in minimize(), caught by spotlbtt.test.
* src/tgbaalgos/minimize.cc (minimize): Don't add acceptance
conditions if the final set is empty.
* src/tgbaalgos/powerset.cc (tgba_powerset): Add the initial state
to acc_list if it is accepting. Also do not compute an SCC build
map if we don't have to build acc_list.
2010-04-13 Alexandre Duret-Lutz <adl@lrde.epita.fr>
"ltl2tgba -Rm" will apply WDBA-minimization only if correct.
* src/tgbatest/ltl2tgba.cc (main): Use WDBA-minimization only when
it is correct. Either we can quickly determine that a formula or
its negation is a safety formula, or we can slowly check the
equivalence of the WDBA-minimized automaton and the original
automaton.
* src/tgbatest/wdba.test: New test.
* src/tgbatest/safety.test: Adjust comment.
* src/tgbatest/spotlbtt.test: Use -Rm.

Better resource handling in minimization.
* src/tgbatest/ltl2tgba.cc (main): Delete the minimized automaton.
* src/tgbaalgos/minimize.cc (minimize): Remove the call to
unregister_variable() at the end. It was both
wrong (unregistering only the first variable) and useless ("delete
del_a" will unregister all these variables). Use a map and a set
to keep track of free BDD variable and reuse them, otherwise the
algorithm would sometimes use more variables than allocated.
2010-03-20 Alexandre Duret-Lutz <adl@lrde.epita.fr>
Implement is_safety_automaton().

construction to determinize the input automaton, the automaton is then
minimized using the standard algorithm, using BDDs to check if states
are equivalent.
2010-03-20 Felix Abecassis <abecassis@lrde.epita.fr>
Modify the powerset algorithm to keep track of accepting states
from the initial automaton.
* src/tgba/tgbaexplicit.cc, src/tgba/tgbaexplicit.hh:
Added class tgba_explicit_number, a tgba_explicit where states are
labelled by integers.
* src/tgbaalgos/powerset.hh, src/tgbaalgos/powerset.cc:
When building the deterministic automaton, keep track of which states
were created from an accepting state in the initial automaton.
The states are added to the new optional parameter (if not 0),
acc_list.
Use tgba_explicit_number instead of tgba_explicit_string to build
the result.
* src/tgbaalgos/scc.cc (spot): Small fix.
Print everything on std::cout.
2011-01-05 Alexandre Duret-Lutz <adl@lrde.epita.fr>
Fix computation of support_conditions for bdd-based TGBA.

account for the conditions from the acceptance relations.
* rc/tgba/tgbabddconcretefactory.hh, rc/tgba/tgbabddconcretefactory.cc

of bdd_support(acceptance_conditions_support).
* src/tgba/tgbabddconcretefactory.cc (finish): Update
data_.acceptance_conditions_support.

* wrap/python/Makefile.am: Use $(SWIG).
2010-12-23 Alexandre Duret-Lutz <adl@lrde.epita.fr>
Get rid of ltihooks.py.
ltihooks.py apparently breaks the import mechanisms of Python 2.6,
causes SWIG's runtime to fail to share a global type table, and
yields various failures in our tests.
* wrap/python/ltihooks.py: Delete.
* wrap/python/Makefile.am (EXTRA_DIST): remove ltihooks.py.
* wrap/python/tests/bddnqueen.py, wrap/python/tests/interdep.py,

wrap/python/tests/modgray.py, wrap/python/tests/optionmap.py,
wrap/python/tests/setxor.py: Do not use ltihooks.
* wrap/python/tests/run.in (pypath): Include the .libs/ directories
in the search path so that Python can find the *.so libraries.
* wrap/python/cgi-bin/ltl2tgba.in: Insert the .libs/ directories
into sys.path instead of importing ltihooks.
2010-12-12 Alexandre Duret-Lutz <adl@lrde.epita.fr>
* NEWS: Summarize recent changes.
2010-12-11 Alexandre Duret-Lutz <adl@lrde.epita.fr>
Merge transitions in tgba_tba_proxy.
With this change the output of

* src/tgbatest/ltl2tgba.test, bench/ltlclasses/run,
bench/ltlcounter/run: Use -ks instead of -k to speed things up.
2010-12-09 Alexandre Duret-Lutz <adl@lrde.epita.fr>
Use a cache to speed up tgba_tba_proxy.

(common_acceptance_conditions_of_original_state): New method.
* src/tgba/tgbatba.cc (tgba_tba_proxy_succ_iterator::~sync)

Move this method...
(recurse_eu): ... outside as a separate function. Likewise for
the universal/eventual result struct.
(reduce_visitor::visit(binop)): Call recurse_eu() once to replace
two calls to is_eventual and is_universal, thus replacing two
recursions by one.
2010-12-01 Alexandre Duret-Lutz <adl@lrde.epita.fr>
Move the eventual-universal functions where the belong.
* src/ltlvisit/syntimpl.cc (eventual_universal_visitor,
is_eventual, is_universal): Move ...

Remove a quadratic behavior in eventual_universal_visitor.
* src/ltlvisit/syntimpl.cc (eventual_universal_visitor): Use
a union to store the eventual and universal properties as two
bit in a bit-field, and "AND" both of them at once.

eventual_universal_visitor::recurse_ev): Replace these
two functions by ...
(eventual_universal_visitor::recurse_): ... this one, that

before some optional operations (like more optimizations, or a
product).
* src/tgbatest/ltl2tgba.cc (-N, -NN): Make sure we print the last

2010-10-07 Alexandre Duret-Lutz <adl@lrde.epita.fr>
Hide the safra_tree_automaton type from the public interface.
We do that because the declaration of this type, which is local to
src/tgba/tgbasafracomplement.cc has a member in an anonymous
namespace, and some versions of g++-4.2 issue a very annoying
warning about this legitimate code. See Bug 29365 on GCC's
Bugzilla. Report by Silien Hong <silien.hong@lip6.fr>.
* src/tgba/tgbasafracomplement.hh (safra_tree_automaton): Do not
forward declare.
(tgba_safra_complement): Use void* instead of
safra_tree_automaton*.
* src/tgba/tgbasafracomplement.cc: static_cast void* to
safra_tree_automaton* anywhere needed.

reductaustr.
2010-04-15 Alexandre Duret-Lutz <adl@lrde.epita.fr>
Fix a long-standing bug in the stronger rule for R and its recent
clone for M.
* src/ltlvisit/contain.cc (reduce_tau03_visitor): Remove
the stronger rules for R and M. They were wrong.
* src/ltltest/reduccmp.test: Test a simpple counterexample.
2010-04-15 Alexandre Duret-Lutz <adl@lrde.epita.fr>
More simplifications rules for M.
* src/ltlvisit/reduce.cc (reduce_visitor): Add the following
implication rewriting rules:
a M (b M c) = a M c if a implies b.
a M (b R c) = a M c if a implies b.
a R (b R c) = a R c if a implies b.
a R (b M c) = b M c if b implies a.
a M (b M c) = b M c if b implies a.
The latter rule was fixed from an incorrectly copied&pasted
rule for a M (b R c) = b R c if b implies a (this is wrong).
Also remove the wrong rule for a W (b U c) = b U c if a implies b.
* src/ltltest/reduccmp.test: Add more tests.
2010-04-15 Alexandre Duret-Lutz <adl@lrde.epita.fr>

(a U b) & Fb = a U b
(a W b) & Fb = a U b
* src/ltltest/reduccmp.test: Test them.

a M b & a M c = a M (b & c)
* src/ltltest/reduccmp.test: More tests.
2010-04-12 Alexandre Duret-Lutz <adl@lrde.epita.fr>
Add LTL reductions for weak until.
* src/ltlvisit/basicreduce.cc: Perform the following reductions.
a U (b | Ga) = a W b
a W (b | Ga) = a W b
a U b | Ga = a W b
a U b | a W c = a W (b | c)
a W b | a W c = a W (b | c)
a U Ga = Ga
a W Ga = Ga
* src/ltltest/reduccmp.test: More tests.
2010-04-07 Alexandre Duret-Lutz <adl@lrde.epita.fr>

src/tgbaalgos/ltl2tgba_fm.cc, src/tgbaalgos/ltl2tgba_lacim.cc:
Add support for W and M.
* src/tgbatest/ltl2neverclaim.test: Test never claim output
using LBTT, this is more thorough. Also we cannot use -N
any more in the spotlbtt.test.
* src/tgbatests/ltl2tgba.cc: Define M and W for ELTL.
* src/tgbatest/ltl2neverclaim.test: Test W and M, and use
-DS instead of -N, because lbtt-translate does not want
to translate these operators for tools that masquerade as Spin.
2010-04-12 Alexandre Duret-Lutz <adl@lrde.epita.fr>
Adjust ltl2tgba.py to call scc_filter() with the "full" option as
appropriate.
* wrap/python/spot.i (spot::scc_filter): Make it available.
* wrap/python/cgi-bin/ltl2tgba.in (reduce_scc): Call scc_filter.
Use the "full" option unless the show_degen_png or
show_never_claim are set. Also reduce_scc the default.
2010-04-08 Alexandre Duret-Lutz <adl@lrde.epita.fr>
* src/ltlvisit/basicreduce.cc: Typo in comment.
2010-04-08 Alexandre Duret-Lutz <adl@lrde.epita.fr>
* NEWS: Summarize recent noteworthy changes.
2010-04-07 Alexandre Duret-Lutz <adl@lrde.epita.fr>
Modernize Bison parsers.
* src/ltlparse/ltlparse.yy, src/tgbaparse/tgbaparse.yy,
src/evtgbaparse/evtgbaparse.yy, src/eltlparse/eltlparse.yy: Use
token types for %destructor and %printer. Remove the yylex hack,
since %name-prefix is now honored by Bison. Also remove the
useless <token> type. Suggested by Akim Demaille.
2010-03-10 Alexandre Duret-Lutz <adl@lrde.epita.fr>
Fix column in LTL error messages, it was off by one.
* src/ltlparse/fmterror.cc (format_parse_errors): Count columns
starting at 1. Older Bison used to start at 0 but changed to
match the GNU Coding Standards.
* src/ltltest/parseerr.test: Add a test case.
2010-03-07 Alexandre Duret-Lutz <adl@lrde.epita.fr>
Do not rewrite F(a & GF(b)) = F(a) & GF(b), this can be harmful.
* src/ltlvisit/basicreduce.cc (basic_reduce_visitor::recurse):
Disable this rule unconditionally.
* src/ltltest/reduccmp.test: Adjust tests.
2010-03-06 Alexandre Duret-Lutz <adl@lrde.epita.fr>
* src/tgba/tgbatba.cc: Fix English in comments.
2010-03-06 Alexandre Duret-Lutz <adl@lrde.epita.fr>
Reverse the order of expected acceptance conditions in
degeneralization.
* src/tgba/tgbatba.cc (tgba_sba_proxy::tgba_tba_proxy): Build the
list of acceptance condition in the reverse order. The order is
still arbitrary, but the bdd_satone() call seems to output the
acceptance conditions that are more used first, and this helps the
degeneralization process.
2010-03-06 Alexandre Duret-Lutz <adl@lrde.epita.fr>
Tweak precedence of "->" and <->.
* src/ltlparse/ltlparse.yy: Change the precedence of "->" and
"<->" so that "a & b -> c" is interpreted as "(a & b) -> c"
instead of "a & (b -> c)". The new interpretation is more
intuitive, and matches that of LBTT.
2010-03-06 Alexandre Duret-Lutz <adl@lrde.epita.fr>
* bench/ltl2tgba/formulae.ltl: Fix three formulae to match the
original paper by Somenzi and Bloem. Reported by Ruediger Ehlers.
2010-03-06 Alexandre Duret-Lutz <adl@lrde.epita.fr>
Fix memory leak introduced in yesterday's change.
* src/tgba/tgbatba.cc (tgba_sba_proxy::tgba_sba_proxy): Do not
forget to free the initial state after usage.
2010-03-06 Alexandre Duret-Lutz <adl@lrde.epita.fr>
Keep acceptance conditions on transitions going to accepting SCCs
by default in scc_filter().
Doing so helps the degeneralization algorithm, because it will
have more opportunity to be in an accepting level when it reaches
the accepting SCCs.
* src/tgbaalgos/sccfilter.cc (filter_iter::filter_iter): Take a
remove_all_useless argument.
(filter_iter::process_link): Use the flag to decide whether to
filter acceptance conditions going to accepting SCCs.
(scc_filter): Take a remove_all_useless argument and pass it to
filter_iter.
* src/tgbaalgos/sccfilter.hh (filter_iter): Add the new argument
and document the function.
* src/tgbatest/tgbatests/ltl2tgba.cc (main): Add option use -R3
for remove_all_useless=false and add -R3f for
remove_all_useless=true.
* src/tgbatest/ltl2tgba.test: Show one case where -R3f makes
the degeneralization worse than -R3.
2010-03-05 Alexandre Duret-Lutz <adl@lrde.epita.fr>
Simplify F(a)|F(b) as F(a|b). Add similar rule for G(a)&G(b).
* src/ltlvisit/basicreduce.cc (basic_reduce_visitor): Replace
the FG(a)|FG(b) == F(Ga|Gb) rule by the above more generic one.
Add the dual rule for G(a)&G(b), as we had none (this one won't
improve anything in the translation, but it is more symmetric
this way). Also simplify some pointer checks.
2010-03-05 Alexandre Duret-Lutz <adl@lrde.epita.fr>
Better selection of the acceptance of the initial state in SBA.
* src/tgba/tgbatba.cc (tgba_sba_proxy::tgba_sba_proxy): Set
cycle_start_ to start in the accepting layer of the degeneralized
automaton if the initial state has an accepting self-loop.
Otherwise, starts at the level of the first acceptance condition
as previously.
(tgba_sba_proxy::get_init_state): Use cycle_start_.
* src/tgba/tgbatba.hh (tgba_tba_proxy::a_): Make it protected so
that we can use it in tgba_sba_proxy::tgba_sba_proxy.
(tgba_sba_proxy::cycle_start_, tgba_sba_proxy::get_init_state):
Declare.
* src/tgbatest/ltl2tgba.test: More tests.
2010-03-05 Alexandre Duret-Lutz <adl@lrde.epita.fr>
Generalize the previous patch to accepting states in SBA.
* src/tgba/tgbatba.cc (tgba_tba_proxy_succ_iterator::sync_): Move
the optimization step added by the previous patch outside the
before the bddtrue check, so that it also applies to accepting
states in SBA.
2010-03-03 Alexandre Duret-Lutz <adl@lrde.epita.fr>
Optimize tgba_tba_proxy and tgba_sba_proxy for states that share
an acceptance condition on all outgoing transitions.
This was motivated by experiments from Rüdiger Ehlers, showing
that "ltl2ba -f 'a U (b U c)'" outperformed "ltl2tgba -f -N -R3 'a
U (b U c)'". With this change and the previous one, it is no
longer the case.
* src/tgba/tgbatba.cc (tgba_tba_proxy_succ_iterator::aut_): Store
a pointer to the source automaton and...
(tgba_tba_proxy_succ_iterator::sync_): ... use it in an extra
optimization step to gather the acceptance conditions common
to all outgoing transitions of the destination state, and pretend
they are on the current (ingoing) transition.
(tgba_tba_proxy::succ_iter): Pass the
source automaton to the constructed iterator.
* src/tgbatest/spotlbtt.test: Test -f -N -R3 -r7.
* src/tgbatest/ltl2tgba.test: Add a test case for 'a U (b U c)'.
2010-03-03 Alexandre Duret-Lutz <adl@lrde.epita.fr>
ltl2tgba: apply -R3 before -D or -DS.
* src/tgbatest/ltl2tgba.cc (main): Call scc_filter() before the
degeneralization, because it might remove useless acceptance
conditions. I realized this while looking at experiments from
Rüdiger Ehlers.
2010-02-24 Alexandre Duret-Lutz <adl@lrde.epita.fr>
* src/sanity/style.test: Better fix for the previous error.
2010-02-23 Alexandre Duret-Lutz <adl@lrde.epita.fr>
Work around a spurious style.test error.
* src/saba/sabacomplementtgba.hh (spot): Rewrite Büchi as B\"uchi
is the BibTex entry used as comment, because some version of sed
will choke on non-ascii character and cause sanity/style.test to
fail.
2010-02-23 Alexandre Duret-Lutz <adl@lrde.epita.fr>
Fix random_graph() not to generate dead states.
This is actually the third time I fix random_graph(). On
2007-02-06 I changed the function not to generated dead states,
but in a way that made it non-deterministic. On 2010-01-20 I made
the function deterministic again, but it started to generate dead
states as a side effect. This time, I'm making sure that dead
states won't come again with a test-case that we should have had
from the beginning.
* src/tgbaalgos/randomgraph.cc (random_graph): Add an extra
indirection array, state_randomizer[], so that we can reorder
states indices after a random selection without actually changing
the value of the indices used by unreachable_states and
nodes_to_process.
* src/tgbatest/randtgba.test: New file.
* src/tgbatest/Makefile.am: Add randtgba.test.
2010-02-17 Alexandre Duret-Lutz <adl@lrde.epita.fr>

configure.
(os.system): Cleanup stale files only when the form has been
submitted.
(list options): Keep track of the selected value.
(draw_acc_run|print_acc_run): set ec=0 to detect if it has been
later set or not. Fix error message when using generalized
automata with degeneralized emptiness checks.
* wrap/python/cgi-bin/Makefile.am (ltl2tgba.py): Substitute @DOT@.
2010-02-02 Alexandre Duret-Lutz <adl@lrde.epita.fr>
* wrap/python/cgi-bin/ltl2tgba.in: Reword description of svg_output.
2010-02-02 Alexandre Duret-Lutz <adl@lrde.epita.fr>
Add SVG output and language containment options to the cgi script.
* wrap/python/cgi-bin/ltl2tgba.in (new): Mark new options as new.

* src/sabaalgos/sabareachiter.hh (process_link): Document argument SI.
* src/eltlparse/public.hh (format_parse_errors): Remove the
non-existing eltl_string argument from the description.
(parse_file): Fix name of parameters in documentation.
2010-01-31 Alexandre Duret-Lutz <adl@lrde.epita.fr>
Build doxygen pictures with libgd to reduce their size.
Doxygen only knows how to call dot with -Tpng, while using
-Tpng:gd produces pictures that are 10 times smaller. Use a
simple wrapper around dot to simplify this.
* doc/dot.in: New file, that wrap the system's dot and replace
-Tpng by -Tpng:gd.
* doc/Makefile.am ($(srcdir)/stamp): Depend on dot.
* doc/Doxyfile.in: Update to 1.6.2.
(DOT_PATH): Set to @srcdir@ to use doc/dot instead of the
system's dot.
* configure.ac: Find the absolute path of dot, and generate
the doc/dot script.

Overhaul LaCIM's ELTL options.
* src/tgbatest/ltl2tgba.cc (syntax, main): Introduce -le to select

2010-01-22 Alexandre Duret-Lutz <adl@lrde.epita.fr>
Fix the computation of the length of multops.
* src/ltlvisit/length.cc (visit(multop*)): New function. "a & b &
c" has length 5, not 4, even though it is stored as And(a,b,c).
This caused reduc.test to fail on some formulae.

2010-01-21 Alexandre Duret-Lutz <adl@lrde.epita.fr>
* src/tgbatest/randtgba.cc: Do not include <string> twice.
2010-01-21 Alexandre Duret-Lutz <adl@lrde.epita.fr>
Speedup reduc.test by not spawning one process per formula.
* src/ltltest/reduc.cc: Add an option -f to read a lot of
formulae from a file. Running a process for each formula was
too slow. Also add an option -h to hide reduced formulae.

link. This bug was discovered on a random generated graph with
a complex accepting cycle.

test case.
2010-01-20 Damien Lefortier <dam@lrde.epita.fr>

const_reverse_iterator.
2010-01-20 Alexandre Duret-Lutz <adl@lrde.epita.fr>
Remove some non-determinism in random_graph()
* src/tgbaalgos/randomgraph.cc (random_graph): Revert the part of
the patch from 2007-02-06 which silently replaced the use of state
index by state pointers. Storing states pointer in this map cause
some non-determinism because of the memory layout. It was almost
impossible to reproduce bugs found by tests based on randtgba.

acceptance conditions in all_n_tuples.
* src/tgba/taatgba.cc, src/tgba/taatgba.hh: Adjust.
2010-01-16 Damien Lefortier <dam@lrde.epita.fr>
Introduce taa_tgba_labelled<label> so that we can build
taa_tgba instances labelled by other objects than strings
in the same way Alexandre did for tgba_explicit.
* src/tgba/taatgba.cc, src/tgba/taatgba.hh: Split taa_tgba in two
levels: taa_tgba with no label and taa_tgba_labelled templated by
the type of the label. Define taa_tgba_string (with the interface
of the former taa_tgba class) and taa_tgba_formula for future use
in ltl2taa.cc.
* src/tgbaalgos/ltl2taa.cc, src/tgbatest/taatgba.cc: Adjust to use
taa_tgba_string.
2010-01-06 Damien Lefortier <dam@lrde.epita.fr>
Fix a longstanding bug reported by Guillaume Sadegh.
* src/eltlparse/eltlscan.ll: Fix a typo.

* src/tgbatest/Makefile.am: Adjust.
* src/tgbatest/ltl2tgba.cc: New option: -xltl to translate an
extended LTL instead of an LTL, a feature previously offered by
eltl2tgba.cc. Also: -R3b to use delete_unaccepting_scc.
* src/tgbatest/spotlbtt.test, src/tgbatest/eltl2tgba.test: Adjust.
2009-11-10 Damien Lefortier <dam@lrde.epita.fr>
* src/tgba/tgbabddcoredata.cc (delete_unaccepting_scc): Fix a bug.
* src/tgbatest/spotlbtt.test: Use the above function with LaCIM
for ELTL which greatly reduce the size of the automata!
2009-12-11 Alexandre Duret-Lutz <adl@lrde.epita.fr>
* src/misc/timer.hh (timer::timer): Initialize running...

Specialize scc_filter when handling tgba_explicit_formula automata.
If the input is a tgba_explicit_formula we can output a
tgba_explicit_formula too, and we want to do that because it is
more space efficient.
* src/tgba/tgbaexplicit.hh (get_label): New method.
* src/tgbaalgos/sccfilter.cc (create_transition): New function,
to handle tgba_explicit_formula and tgba_explicit_string output
differently.

(scc_filter): Use filter_iter<tgba_explicit_formula> or
filter_iter<tgba_explicit_string> depending on the input tgba
type.
2009-11-20 Alexandre Duret-Lutz <adl@lrde.epita.fr>

after removing acceptance conditions.
2009-11-18 Alexandre Duret-Lutz <adl@lrde.epita.fr>
Remove prune_scc(), prune_acc(), and related fonctions.
* src/tgba/tgbareduc.cc, src/tgba/tgbareduc.hh (prune_scc,
prune_acc, remove_component, compute_scc, remove_acc,
is_not_accepting, delete_scc, is_terminal, remove_scc,
display_scc): Remove anything related to the simplification of
SCCs.
2009-11-18 Alexandre Duret-Lutz <adl@lrde.epita.fr>
Replace prune_scc() by scc_filter().
prune_scc() leaked memory and failed to remove chains of useless SCCs.
* src/tgbaalgos/reductgba_sim.cc (reduc_tgba_sim): Call
scc_filter() instead of prune_scc(), and do it before running
any simulation-based reduction.

tgba*.
* src/tgbatest/ltl2tgba.cc, src/tgbatest/reductgba.cc: Call
scc_filter() instead of prune_scc().

files.

* src/tgbaalgos/scc.cc (scc_map::build_map): Mark SCCs that are
not trivial.

of by pointer.
* src/tgbaalgos/cutscc.cc, src/tgbaalgos/cutscc.hh: Fix copyright
header.
2009-11-13 Alexandre Duret-Lutz <adl@lrde.epita.fr>
Replace the hash key construction of LTL formulae by a simple
counter updated each time we create a new (unique) formula.
Doing so saves a lot of memory during the translation of the
ltlcounter formulae, because the formulae are quite big and
storing a string representation of each formula on its node was a
bad idea. For instance with n=12, the translation now uses 40MB
where it used 290MB. (Note: in both cases, 20MB is being used by
the BDD cache.)
* src/ltlast/formula.hh (hash_key_): Rename as ...
(count_): ... this.
(hash): Adjust.
(max_count): New static variable to count the number of
formulae created.
(formula): Update max_count and set count_.
(dump): Make it a virtual pure method.
(set_key_): Remove.
(formula_ptr_less_than): Speed up and return false when
the two formula pointer are equal.
* src/ltlast/formula.cc (set_key_, dump): Remove.
* src/ltlast/atomic_prop.cc, src/ltlast/atomic_prop.hh,
src/ltlast/automatop.cc, src/ltlast/automatop.hh,
src/ltlast/binop.cc, src/ltlast/binop.hh, src/ltlast/constant.cc,
src/ltlast/constant.hh, src/ltlast/multop.cc,
src/ltlast/multop.hh, src/ltlast/unop.cc, src/ltlast/unop.hh:
Empty the constructor (do not precompute the dump_ anymore),
and add a dump() implementation.
2009-11-12 Alexandre Duret-Lutz <adl@lrde.epita.fr>
Use -l wherever we where expecting ltl2tgba to default to LaCIM.
* bench/ltl2tgba/algorithms: Use -l for all LaCIM invocations.
* src/tgbatest/dupexp.test, src/tgbatest/emptchk.test,
src/tgbatest/spotlbtt.test: Likewise.
2009-11-12 Alexandre Duret-Lutz <adl@lrde.epita.fr>
Cleanup the help of ltl2tgba.
* src/tgbatest/ltl2tgba.cc (syntax): Reorganize the help text, so
that we can find options without resorting to grep... Also
cleanup the program name if it is a libtool wrapper.
2009-11-12 Alexandre Duret-Lutz <adl@lrde.epita.fr>
* src/tgbatest/ltl2tgba.cc (-l): New option to select the lacim
translation. It still is the default translation.
(opt_fm, opt_taa): Replace these two variables by ...
(translation): ... this enum. And use a switch to call the
correct translation.
2009-11-11 Alexandre Duret-Lutz <adl@lrde.epita.fr>
Remove python bindings for ltl::clone and ltl::destroy.
* wrap/python/spot.i: Do not include clone.hh and destroy.hh.
2009-11-10 Alexandre Duret-Lutz <adl@lrde.epita.fr>
Typo from a previous patch.
* src/tgbaalgos/ltl2tgba_fm.cc (ltl_to_tgba_fm): Fix a typo
introduced three patches ago in the handling of unobserved events.
2009-11-10 Alexandre Duret-Lutz <adl@lrde.epita.fr>
Do not comment states in the never claim by default. It takes too
much time when the formula is large, and it is useless when the
purpose is model-checking with Spin.
* src/tgbaalgos/neverclaim.hh (never_claim_reachable): Add the
comments option.
* src/tgbaalgos/neverclaim.cc (never_claim_bfs,
never_claim_reachable): Honor the comment option.
* src/tgba/tests/ltl2tgba.cc (-N): Do not comment states.
(-NN) New option to output a commented never claim.

* src/tgbaalgos/ltl2taa.cc: Do NOT use the same bdd_dict for both
the translation and the language containment checker.
* src/tgbatest/spotlbtt.test: Update TAA related tests.
2009-11-10 Alexandre Duret-Lutz <adl@lrde.epita.fr>
Use tgba_explicit_formula instead of tgba_explicit_string in FM.
This gives a nice speedup (>1.4) in the ltlcounter benchmark,
because we no longer have to generate a copy the string
representations of the LTL formulae.
* src/tgbaalgos/ltl2tgba_fm.cc: Adjust. Also get rid of the
formulae_seen map, since we can now ask the tgba_explicit_formula
if it knows the state.
2009-11-10 Alexandre Duret-Lutz <adl@lrde.epita.fr>
Ease debugging of LTL formulae leaks.
* src/tgbatest/ltl2tgba.cc: Dump all LTLinstances with their
reference count.
2009-11-10 Alexandre Duret-Lutz <adl@lrde.epita.fr>
Introduce tgba_explicit_labelled<label> so that we can build
tgba_explicit instances labelled by other objects than strings.
* src/tgba/tgbaexplicit.cc, src/tgba/tgbaexplicit.hh:
Split tgba_explicit in two levels: tgba_explicit with unlabelled
states, and tgba_explicit_labelled templated by the type of
the label. Define tgba_explicit_string (with the interface
of the former tgba_explicit class) and tgba_explicit_formula
for future use in ltl2tgba.cc.

use tgba_explicit_string when appropriate.
2009-11-09 Alexandre Duret-Lutz <adl@lrde.epita.fr>
Do not use the Boost macro from the Autoconf macro archive.
* m4/boost.m4: Rewrite like I already did in Vaucanson.
2009-11-09 Alexandre Duret-Lutz <adl@lrde.epita.fr>
* src/tgbatest/ltlcounter.test (run): Do not run with n=12, as
the test case might become too slow for the autobuilder.
2009-11-06 Alexandre Duret-Lutz <adl@lrde.epita.fr>
Add a benchmark using Kristin Y. Rozier's LTLcounter scripts.
* bench/ltlcounter/README, bench/ltlcounter/run,
bench/ltlcounter/plot.gnu, bench/ltlcounter/defs.in,
bench/ltlcounter/Makefile.am: New files.
* bench/Makefile.am (SUBDIRS): Add ltlcounter.

2009-11-06 Alexandre Duret-Lutz <adl@lrde.epita.fr>
Use a timer to clock the different phases of the translation.
* src/tgbatest/ltl2tgba.cc: Add option -T.

2009-11-07 Alexandre Duret-Lutz <adl@lrde.epita.fr>
Change the way references are counted to speedup cloning.
Before this patch, every time you cloned a formula, the clone
visitor would recurse into the entire AST to increment the
reference count of all nodes. When running ltl2tgba_fm on
the formula generated by "LTLcounterLinear.pl 8", approx 27% of
the time was spent in the clone visitor.
After this patch, cloning a formula is just an increment of the
reference count of the top node. Children are decremented only
when the top node's ref count is decremented to zero. With this
change, clone() and destroy() become constant time, the
ltl2tgba_fm spend only 0.01% of the time cloning formulae.
* src/ltlast/automatop.cc (~automatop): Decrement children.
(instance): Decrement children if the instance already exists.
* src/ltlast/binop.cc, src/ltlast/multop.cc, src/ltlast/unop.cc:
Likewise.
* src/ltlvisit/clone.cc (clone): Simplify, now we only need to
call ref().
* src/ltlvisit/destroy.cc (destroy): Simplify, now we only need
to call unref().
(destroy_visitor): Remove, no longer needed.
2009-11-07 Alexandre Duret-Lutz <adl@lrde.epita.fr>
Make it easier to debug reference counts in LTL nodes.
* src/ltlast/automatop.cc, src/ltlast/automatop.hh,
src/ltlast/binop.cc, src/ltlast/binop.hh, src/ltlast/multop.cc,
src/ltlast/multop.hh, src/ltlast/unop.cc, src/ltlast/unop.hh:
Add a dump_instance() static method to all class.
* src/ltltest/readltl.cc: Add option -r to dump all instances
with their reference count, after parsing and after deletion.
2009-11-07 Alexandre Duret-Lutz <adl@lrde.epita.fr>
Better types for instance maps.
* src/ltlast/unop.hh (map): Use unop* as values.
* src/ltlast/binop.hh (map): Use binop* as values.
* src/ltlast/multop.hh (map): Use multop* as values.
* src/ltlast/automatop.hh (paircmp): Rename as tripletcmp.
(map): Use automaton* as values, not formula*.
2009-11-07 Alexandre Duret-Lutz <adl@lrde.epita.fr>
Add missing instance_count() in automatop and eltl2tgba.
* src/ltlast/automatop.hh, src/ltlast/automatop.cc: Add missing
instance_count() functions.
* src/tgbatests/eltl2tgba.cc: Add missing instance_count()
assertions at the end.
* src/tgbatests/ltl2tgba.cc: Also call automatop::instance_count(),
even if automatop are not used in ltl2tgba yet. This way we won't
forget once eltl2tgba and ltl2tgba are merged.
2009-11-07 Damien Lefortier <dam@lrde.epita.fr>
* src/tgba/taa.cc, src/tgbatest/taa.cc: Adjust.
2009-11-07 Damien Lefortier <dam@lrde.epita.fr>

* src/tgbatest/ltlcounter.test (lcdir): Adjust definition to
new value of $srcdir.
(run): Fix setting of $run after $n = 2. Using run=: would in
fact disable all the big tests...
2009-11-05 Alexandre Duret-Lutz <adl@lrde.epita.fr>
* src/tgbatest/ltlcounter.test (run): Only construct small
formulae (i.e. n<=2) under valgrind. The test case is too
slow otherwise.

before -taa. Remove -r8 and -fr8, since they do not exist.
2009-10-28 Alexandre Duret-Lutz <adl@lrde.epita.fr>
* src/tgba/tgbacomplement.cc (state_complement): Remove the copy
constructor. It does the same thing as the default copy
constructor, and g++ 4.2.3 complained that the copy constructor
of spot::state was not called. Reported by Denis Poitrenaud.
2009-10-28 Alexandre Duret-Lutz <adl@lrde.epita.fr>
* src/ltlast/formula_tree.cc (instanciate, arity): Add a useless
return 0 at the end to prevent g++ 4.2.3 from complaining about
a missing return. Reported by Denis Poitrenaud.
2009-10-23 Alexandre Duret-Lutz <adl@lrde.epita.fr>
* src/tgbatest/kv.test: Don't run valgrind on dot!
2009-10-16 Alexandre Duret-Lutz <adl@lrde.epita.fr>

Improve ltl_to_taa.
* src/tgba/taa.cc, src/tgba/taa.hh: taa_succ_iterator is not
on-the-fly anymore allowing some redundant transitions to be
removed. Also a new function to output a TAA.
* src/tgbaalgos/ltl2taa.cc, src/tgbaalgos/ltl2taa.hh: Add the
refined rules from Tauriainen.
* src/tgbatest/ltl2tgba.cc: Use -c to activate refined rules in

2009-10-16 Damien Lefortier <dam@lrde.epita.fr>
Add a new algorithm (from Tauriainen) to translate LTL formulae to
TGBA which uses TAA as an intermediate representation. This is a
basic version, optimizations and enhancements will come later.

2009-05-28 Alexandre Duret-Lutz <adl@lrde.epita.fr>
Number states using negative values and SCCs using nonnegative
values.
Before this change states were numbered using positive values and
SCCs using negative values. That meant the user had to work with
negative values. With this changes, the nonnegative values used
to label SCCs can also directly be used as index in the scc_map_.
* src/tgbaalgos/scc.hh (scc_map::scc_of_state,
scc_map::cond_set_of, scc_map::acc_set_of, scc_map::states_of,
scc_map::initial, scc_map::scc_type, scc_map::succ,

number of the SCC instead of taking it as argument.
(scc_map::scc_num_): Delete this variable. scc_map_.size() gives

acceptance conditions, with VERBOSE is set.
(build_map): Fill the new scc_map::scc::cond field.
2009-05-28 Alexandre Duret-Lutz <adl@lrde.epita.fr>
* src/tgbaalgos/scc.cc (scc_map::relabel_component): Make sure
that the old label of each state is strictly positive. The
previous assertion (inherited from gtec) of "!= -1" is wrong,
because all negative values are now used to number SCCs.

src/ltlvisit/postfix.cc, src/ltlvisit/postfix.hh,
src/ltlvisit/reduce.cc, src/ltlvisit/syntimpl.cc,
src/ltlvisit/tostring.cc: Because LTL and ELTL formulae share the
same class hierarchy, LTL visitors need to handle automatop nodes
to compile. When it's meaningful the visitor applies on automatop
nodes or simply assert(0) otherwise.

* src/evtgbaparse/evtgbaparse.yy, src/tgbaparse/tgbaparse.yy,
src/ltlparse/ltlparse.yy: The sections "%{ ... %}" should now be

whether they should end up in the parser's header file or its cc
file. Also use %language, %locations, %defines, instead of
command-line arguments.
* src/evtgbaparse/Makefile.am, src/tgbaparse/Makefile.am,
src/ltlparse/Makefile.am: Remove the --locations, --defines
and --languages in the call to bison. Add -Wall -Werror to
catch more errors.

2008-03-11 Alexandre Duret-Lutz <adl@lrde.epita.fr>

* src/tgbaalgos/reductgba_sim.cc (reduc_tgba_sim): Add two
assert(). This patch has been lying in my tree since 2007-04-30.
2008-01-08 Alexandre Duret-Lutz <adl@lrde.epita.fr>
This is something Soheib and I worked on back in July, but a
intricate memory corruption bug prevented me to check the patch
in. It took me two days to realize why find_state() must do a
double loop over the candidates to check for equality before
checking for inclusion(s).
* iface/gspn/ltlgspn.cc: New options, -e45 and -n.
* iface/gspn/ssp.cc, iface/gspn/ssp.hh: Handle these.

Add support for -r8/-fr8.
* src/tgbatest/spotlbtt.test: Also check -R1q -R1t -R2q -R2t.
2007-04-29 Alexandre Duret-Lutz <adl@src.lip6.fr>
* src/ltlvisit/reduce.cc (reduce): Repeat the reduction as
long as the formula changes, it makes more sense when
combining algorithm. E.g. basic reductions can help language
containment and vice-versa.
2007-04-20 Alexandre Duret-Lutz <adl@src.lip6.fr>
* src/tgbatest/spotlbtt.test: Disable formula rewriting during
construction.
2007-04-19 Alexandre Duret-Lutz <adl@src.lip6.fr>
* src/ltltest/reduc.cc (main): More cases to test.
* src/ltlvisit/basicreduce.cc (basic_reduce_visitor::visit):
Simplify the formula again after FX->XF and GX->XG permutations.
This is so that formulae like GFXXa become GFa and not just GFXa.
* src/ltlvisit/contain.cc (reduce_tau03_visitor): Fix a typo
in the rules for i|j or i&j, resulting in missing simplifications.
* src/ltlvisit/contain.cc (reduce_tau03_visitor): Simplify the
rules for "a U b" and "a R b", an implication check is enough.
2007-04-17 Alexandre Duret-Lutz <adl@src.lip6.fr>
* src/misc/bddalloc.cc (bdd_allocator::initialize): Call
bdd_isrunning() and don't run bdd_init() if it has already been
called.
2007-02-06 Alexandre Duret-Lutz <adl@src.lip6.fr>
* src/tgbaalgos/randomgraph.cc (random_graph): Fix the
generation of the graph. Some states had no successors or
duplicate transitions because of that bug.
2006-08-30 Alexandre Duret-Lutz <adl@src.lip6.fr>
* HACKING: We need Bison 2.3.
* evtgbaparse/evtgbaparse.yy, ltlparse/ltlparse.yy,
tgbaparse/tgbaparse.yy: Fix Bison warnings about unset $$.
* src/tgbaparse/Makefile.am (tgbaparse_HEADERS): Also
install location.hh and position.hh, since we no longer share
those of ltlvisit.
* src/evtgbaparse/Makefile.am (evtgbaparse_HEADERS): Likewise.

default.
* src/ltlvisit/contain.cc: Style.
* src/ltltest/reduc.cc: Simplify using the reduce() interface
instead of reduce_tau03.
* src/tgbatest/ltl2tgba.cc: Likewise. Add -fr5, -fr6, and -fr7
options.
* src/tgbatest/spotlbtt.test: Remove cases using "-c", since its
current implementation is not always correct (and apparently
reduces less than -fr7).
2006-08-01 Alexandre Duret-Lutz <adl@src.lip6.fr>
* src/evtgbatest/evtgbaparse.yy, src/evtgbaparse/evtgbascan.ll,

distinguish acceptance conditions that are identical in both
operands.

* src/tgba/bdddict.cc, src/tgba/bdddict.hh (free_annonymous_list_of):
Rename as ...
(free_anonymous_list_of): ... this, and correct their update on
release. Also correct yesterday's the correction (ahem!).
(dump): Improve verbosity.
* src/misc/freelist.cc (free_list::remove, free_list::insert): Fix
longstanding thinkos.
(free_list::free_count): New function.
Merge this fix from proviso-branch:
2006-05-22 Alexandre Duret-Lutz <adl@src.lip6.fr>
* src/misc/bddalloc.cc (bdd_allocator::bdd_allocator): Count the
number of BDD variable after they have been allocated. Otherwise
the first bdd_dict() created was leaking BDD variable #1.
* src/tgba/tgbabddconcrete.hh, src/tgba/tgbaexplicit.hh,
src/tgba/tgbaproduct.hh, src/tgba/tgbareduc.hh, src/tgba/tgbatba.hh:
Remove superfluous class qualifiers worrying gcc 4.1.2.
2006-07-13 Alexandre Duret-Lutz <adl@src.lip6.fr>
* src/tgbaalgos/ltl2tgba_fm.hh, src/tgbaalgos/ltl2tgba_fm.cc
(ltl_to_tgba_fm): Add a new option "containment_checks" to enable
some language containment checks (via emptiness checks) during the
translation. This first attempt currently only use containment
checks to merge states bisimulating each other.
* src/tgbatest/ltl2tgba.cc: Bind this to option "-c".
* src/tgbatest/spotlbtt.test: Check it.
* src/tgba/bdddict.cc (bdd_dict::unregister_variable): Correctly
call release_n(), not remove() to repopulated the freelist of
anonymous BDD variables. New code I'm working on triggered an
assertion inside remove(), but I'm surprised this bug hadn't
manifested before !
2006-06-13 Alexandre Duret-Lutz <adl@src.lip6.fr>

iface/gspn/dottyssp.cc: s/exeption/exception/g.
2006-04-05 Alexandre Duret-Lutz <adl@src.lip6.fr>
* src/tgbaalgos/gtec/gtec.cc, src/tgbaalgos/gtec/gtec.hh:
(couvreur99_check_shy_ssp): Add a onepass_ attribute to
disable the "shyness", and do not increment pos before calling
find_state since gspn's implementation uses it.
* iface/gspn/ssp.cc: Enable "onepass_" for all "shy" variants,
and also fix find_state for the case where onepass_ is
disabled (but I do not yet know why the latter fix isn't enough).
2006-02-15 Alexandre Duret-Lutz <adl@src.lip6.fr>
* src/tgbaalgos/gtec/gtec.cc: Add a third level hash, to split
each container into lists of states with identical formula states.
* iface/gspn/ltlgspn.cc, src/tgbaalgos/gtec/gtec.cc,
src/tgbaalgos/gtec/gtec.hh: New option (-e6) to disable

greatspn's new container() function.
* iface/gspn/ssp.hh (gspn_ssp_interface): Add a doublehash option.

2006-02-11 Alexandre Duret-Lutz <adl@src.lip6.fr>
* src/tgbatest/ltl2tgba.cc: Pacify sanity.test.
2006-02-10 Alexandre Duret-Lutz <adl@src.lip6.fr>
* src/tgbaparse/public.hh (tgba_parse): Take two environments
instead of one : one for the atomic propositions, and one
for the acceptance conditions. This way it's easy for
the tools in iface/gspn/ to require some atomic proposition
to be declared and allow any acceptance conditions (there is nothing
to adjust in this files because of the default value of the argument).
* src/tgbaparse/tgbaparse.yy: Adjust.
* src/tgbatest/ltl2tgba.cc, src/tgbatest/readsave.cc,
src/tgbatest/reductgba.cc, src/tgbatest/tgbaread.cc: Adjust calls.
* src/tgbaparse/tgbaparse.yy (acc_decl): Diagnose acceptance
conditions rejected by the environment.
* iface/gspn/ltlgspn.cc (display_stats): New function.
(main): Use it.
* iface/gspn/ssp.cc: Add more counters for statistics.
* iface/gspn/ssp.cc (couvreur99_check_shy_ssp::find_state): Correctly
update the emptiness statistics.
* m4/gspnlib.m4: Typo.
2006-02-05 Alexandre Duret-Lutz <adl@src.lip6.fr>
* iface/gspn/ssp.cc: Pacify sanity.test.
2006-02-03 Alexandre Duret-Lutz <adl@src.lip6.fr>
* iface/gspn/ssp.cc (couvreur99_check_shy_ssp::find_state): Typo.
2006-02-02 Alexandre Duret-Lutz <adl@src.lip6.fr>
* src/tgbaalgos/gtec/gtec.cc (couvreur99_check_shy::check):
Reorganize this function so that syntactically there is only one
loop over the successors, and not two. Call reintroduce the call
to couvreur99_check_shy::state_index(), needed by SSP, and
suppress that to index_and_insert introduced on 2004-12-29. Also
split the "group" option in two: "group" and "group2". "group2"
is the equivalent of the older "group", while the new "group" is
weaker and faster.
(couvreur99_check_shy::find_state): Change prototype as needed by
the algorithm.
* src/tgbaalgos/gtec/gtec.hh: Adjust.
* src/tgbaalgos/gtec/nsheap.hh, src/tgbaalgos/gtec/nsheap.cc
(index_and_insert): Remove.
* iface/gspn/ssp.cc (couvreur99_check_shy_ssp::find_state): Adjust

check algorithms, and a text box for options.
2006-01-05 Alexandre Duret-Lutz <adl@src.lip6.fr>
* src/tgbaalgos/ndfs_result.hxx (ndfs_result::construct_cycle):
Initialize tmp to suppress a GCC 4.0.1 warning (seen on Darwin).
2006-01-03 Alexandre Duret-Lutz <adl@src.lip6.fr>

* src/tgbatest/randtgba.cc (default_algos): Test the "ordering"
heuristic.
2005-09-20 Heikki Tauriainen <heikki.tauriainen@tkk.fi>
* src/tgbaalgos/tau03opt.cc: Include <vector>.
(tau03_opt_search): Add option "ordering" (off by default).
If enabled, initialize an explicit ordering for acceptance
conditions into the new member "cond" (a vector of bdds).

acceptance conditions to a subset that maximizes the number
of initial consecutive conditions covered by the set in the
condition ordering.

the way in which elements are pushed on the stack, there can
be at most one element with a given depth in the stack at any
one time).

Before this change, all automata would construct their own
dictionaries (map of BDD variables to LTL formulae). This was
cumbersome, because to multiply two automata we had to build a
common dictionary (the union of the two LTL formula spaces), and
install wrappers to translate each automaton's BDD answers into
the common dictionary. This translation, that had to be repeated
when several products were nested, was time consuming and was a
hindrance for some optimizations.
In the new scheme, all automata involved in a product must
share the same dictionary. An empty dictionary should be
constructed by the user and passed to the automaton' constructors
as necessary.
This huge change removes more code than it adds.
