* NEWS: mention this fix.
* bench/stutter/stutter_bench.sh, bench/stutter/user.sh: Path to spot
binaries would include an inexistant src directory.
* bench/stutter/stutter_invariance_formulas.cc: Add override qualifier
to satisfy -Wsuggest-override.
* 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.
