* src/tgbaalgos/stutter.cc: Add a new variant of Etessami's check,
closer to his original paper in IPL.
* src/ltltest/stutter.test: Add more tests.
* bench/stutter/user.sh: Include this new variant in the benchmark.
* bench/stutter/stutter_invariance_randomgraph.cc: Update to recent
changes. If an algorithm took more that 30s on an average for a set of
parameters, avoid running it with more states. Take the density and
ap count as parameter. Output all the algorithms on the same line.
Add additional statistics about automata.
* bench/stutter/stutter_invariance_formulas.cc: Update to recent
changes. Output all the algorithms on the same line.
Add additional statistics about automata.
* bench/stutter/stutter_bench.sh: Use a Makefile to manage concurrency.
* bench/stutter/README: Update.
* bench/stutter/stutter_bench.sh: Add headers in the CSV files, and also
run stutter_invariance_randomgraph.
* bench/stutter/stutter_invariance_formulas.cc: Remove space from CSV
output.
* bench/stutter/stutter_invariance_randomgraph.cc: Likewise, plus fix
the call to is_stutter_invariant(), and return an average time.
* bench/stutter/stutter.ipynb: Adjust.
* bench/stutter/README: Simplify.
* bench/stutter/Makefile.am: Distribute the script and python notebook.
* bench/stutter/stutter_bench.sh: Collect benchmarks for different
number of atomic propositions in a single csv file.
* bench/stutter/stutter.ipynb: Visualize benchmarks generated by
stutter_bench.sh.
* src/ltlvisit/apcollect.hh,
src/ltlvisit/apcollect.cc (create_atomic_prop_set): New function.
* src/bin/randltl.cc, bench/stutter/stutter_invariance_randomgraph.cc:
Use it.
* src/ltltest/ltlfilt.test: Add more tests.
* src/ltltest/stutter.test: New test.
* src/ltltest/Makefile.am: Adjust.
* src/bin/ltlfilt.cc: Catch std::runtime_error.
* src/tgba/tgbasl.hh (make_tgbasl): New function.
* src/tgba/tgbagraph.hh (make_tgba_graph): Add another overload.
* src/tgbaalgos/stutter_invariance.cc,
src/tgbaalgos/stutter_invariance.hh: Take the algorithm version as an
optional integer, and call getenv() only once.
* bench/stutter/stutter_invariance_randomgraph.cc,
bench/stutter/stutter_invariance_formulas.cc: Simplify using the
above functions.
* src/tgbaalgos/closure.cc, src/tgbaalgos/closure.hh: Using vectors
instead of sets and unordered maps, adding an overload to handle rvalue
references.
* src/tgbaalgos/stutterize.cc, src/tgbaalgos/stutterize.hh: Adding
an overload to handle rvalue references.
* bench/stutter/stutter_invariance_formulas.cc,
bench/stutter/stutter_invariance_randomgraph.cc: Automata are modified
in-place by is_stutter_invariant so they have to be copied before being
processed.
* src/tgbaalgos/stutter_invariance.cc,
src/tgbaalgos/stutter_invariance.hh: Use the in-place version of
closure and sl.
* src/tgbaalgos/closure.cc, src/tgbaalgos/closure.hh:
Add closure function.
* src/tgbaalgos/stutterize.cc, src/tgbaalgos/stutterize.hh:
Add two implementations of "self-loopize" function.
* src/tgbaalgos/Makefile.am: Add them.
* src/tgba/tgbasl.cc, src/tgba/tgbasl.hh: On-the-fly implementation of
self-loopize.
* src/tgba/Makefile.am: Add it.
* src/tgbatest/ltl2tgba.cc, src/tgbatest/stutter_invariant.test: Test
closure and sl.
* src/tgbatest/Makefile.am: Adjust.
* src/bin/ltlfilt.cc: Modify stutter-invariant option to use
automaton-based checking rather than syntactic-based checking.
