      Add 2 benchmarks directories. · 414956c5
      Flix Abecassis authored
      Add an algorithm to split an automaton in several automata.
      * bench/scc-stats: New directory.  Contains input files and test
      program for computing statistics.
      * bench/split-product: New directory.  Contains test program for
      synchronised product on splitted automata.
      * bench/split-product/models: New directory.  Contains Promela
      files and LTL formulae that should be verified by the models.
      * src/tgba/tgbafromfile.cc, src/tgba/tgbafromfile.hh:
      New files.  Small class to avoid long initializations with numerous
      constants when translating to TGBA many LTL formulae from a
      given file.
      * src/tgbaalgos/cutscc.cc, src/tgbaalgos/cutscc.hh:
      New file.  From a single automaton, create, at most,
      X sub automata.
      * src/tgbaalgos/scc.cc, src/tgbaalgos/scc.hh:
      Adjust to compute self-loops count.

      * src/tgbatest/Makefile.am: Adjust.
      * src/tgbaalgos/scc.hh: More documentation.
      * src/tgbaalgos/scc.cc (scc_recurse): Fix computation of
      acc_paths and dead_paths.  Prevent recursions in states that
      have already been visited.

      Number states using negative values and SCCs using nonnegative · 15b3b9e0
      Alexandre Duret-Lutz authored
      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,
      scc_map::accepting): Adjust prototypes to take or return unsigned
      * src/tgbaalgos/scc.cc: Adjust prototypes of the above functions.
      (scc_map::build_map, scc_map::relabel_component): Number states
      using negative values, and SCCs using nonnegative values.
      (dump_scc_dot): Adjust to use nonnegative values.

      point in using a map since the SCC are numbered in sequence.
      * src/tgbaalgos/scc.hh (scc_map::relabel_component): Return the
      number of the SCC instead of taking it as argument.
      (scc_map::scc_num_): Delete this variable.  scc_map_.size() gives
      the same information.
      (scc_map::scc_map_type): Define using std::vector instead of
      * src/tgbaalgos/scc.cc: Adjust all uses.

      Keep track of conditions in SCC, and add a more verbose dump. · 07ead613

      scc_map::cond_set_of, scc_map::acc_set_of, scc_map::states_of):
      New functions.
      (scc_map::scc::conds): New attribute.
      (dump_scc_dot): Take an optional VERBOSE argument.
      * src/tgbaalgos/scc.cc (scc_map::scc_of_state,
      scc_map::cond_set_of, scc_map::acc_set_of, scc_map::states_of):
      Implement these new functions.
      (dump_scc_dot): Display number of states, conditions and
      acceptance conditions, with VERBOSE is set.
      (build_map): Fill the new scc_map::scc::cond field.
