This fixes#441, reported by Jérôme Dubois.
* tests/python/mergedge.py: New file.
* tests/Makefile.am: Add it.
* spot/twa/twagraph.cc (merge_edges): Fix initialization of second
loop.
* NEWS: Mention the bug.
* doc/org/satmin.tex: Use a plain background color instead of some
hashed lines pattern. This reduces the size of the resulting SVG
file from 1.9MB to 50kB after minification.
* doc/org/satmin.org: Adjust to mention autfilt.
spot/twaalgos/postproc.hh: Introduce options Buchi and
GeneralizedBuchi. The latter is similar to TGBA but the former differs
from BA in that it does not imply state-based acceptance, since that
can be specified separately. Also all other acceptance types are not
abbreviated, so those new names make more sense.
* NEWS: Mention that.
* spot/twaalgos/postproc.cc, spot/twaalgos/translate.cc: Adjust
to support Buchi and GeneralizedBuchi without breaking BA and TGBA.
* bin/autfilt.cc, bin/common_aoutput.cc, bin/common_post.cc,
bin/ltl2tgta.cc, doc/org/tut10.org, doc/org/tut12.org,
doc/org/tut30.org, python/spot/__init__.py,
tests/python/automata.ipynb, tests/python/langmap.py,
tests/python/misc-ec.py, tests/python/satmin.ipynb,
tests/python/satmin.py, tests/python/toweak.py: Use the new names.
* tests/Makefile.am: Add missing langmap.py.
* spot/twaalgos/synthesis.cc, spot/twaalgos/synthesis.hh: New files
regrouping the functionnalities split and apply_strategy for synthesis
* python/spot/impl.i, spot/twaalgos/Makefile.am: Add them.
* spot/twaalgos/split.cc, spot/twaalgos/split.hh: No longer contains
the splits necessary for for synthesis, moved to
spot/twaalgos/synthesis.cc, spot/twaalgos/split.hh Split is now faster
and reduces the number of intermediate states, reducing the overall
size of the arena
* spot/misc/game.cc, spot/misc/game.hh: Renaming propagate_players to
alternate_players.
* tests/core/ltlsynt.test, tests/python/split.py: Update tests.
* bin/ltlsynt.cc: Adjust to new split. Swap order of split and
to_parity for lar.
This is required by an upcoming patch by Jérôme, solving reachability
games.
* spot/misc/game.cc (highlight_strategy): Do not require parity
acceptance.
This is a bug I introduced while merging Philipp's patch.
* spot/misc/game.cc (parity_game::solve): Set the strategy for player
0 in useless SCCs.
(parity_game::fix_scc): Do not use sub_game_ to detect edges exiting
the SCC.
* tests/python/game.py: New file.
* tests/Makefile.am: Add it.
* spot/misc/game.cc, spot/misc/game.hh: More efficient implementation
of Zielonka's algorithm to solve parity games. Now supports SCC
decomposition and efficient handling of certain special cases.
* doc/org/concepts.org: Document "strategy" and "state-winner"
properties.
* bin/ltlsynt.cc, tests/python/paritygame.ipynb: Adjust.
* tests/core/ltlsynt.test: Add more tests.
* spot/twaalgos/aiger.cc, spot/twaalgos/aiger.hh: Reimplement
print_aiger for speed gain, also heuristics to minimize the number
of gates as well as different encoding types have been added.
* bin/ltlsynt.cc: Make the new options for print-aiger available.
* tests/core/ltlsynt.test: Adjust tests.
This restricts the time spent in translating sub-formulas for
implication tests by limiting the associated automata to 64 states by
default. Doing so this does worsen any test case, and actually remove
all calls the BuDDy's GC in bdd.test.
* spot/twaalgos/translate.cc, spot/twaalgos/translate.hh,
spot/tl/simplify.cc, spot/tl/simplify.hh, spot/tl/contain.hh,
spot/tl/contain.cc, spot/twaalgos/ltl2tgba_fm.cc,
spot/twaalgos/ltl2tgba_fm.hh: Add support for the option or
its constraint via an output_aborter.
* bin/spot-x.cc, NEWS: Document it.
* tests/core/bdd.test: Adjust and augment test case.
* python/spot/__init__.py (setup): Reduce the default maximal width of
automata so that Jupyter output does not add an horizontal scroll bar
for a few pixels.
* tests/python/automata-io.ipynb: Adjust.
