      sat: generalize the code for reading the solution · 90c106f8
      Alexandre Duret-Lutz authored
      * src/misc/satsolver.cc, src/misc/satsolver.hh (satsolver_get_solution):
      New function, that accepts a solution split on multiple 'v ' lines.
      * src/tgbaalgos/dtbasat.cc, src/tgbaalgos/dtgbasat.cc (get_solution):
      Remove, and adjust existing code to use satsolver_get_solution().
      * src/tgbatest/readsat.cc, src/tgbatest/readsat.test: New files.
      * src/tgbatest/Makefile.am: Add them.
      * src/bin/man/spot-x.x: Mention the SAT competition rules for
      the expected input/output format.

      Alexandre Duret-Lutz authored
      * src/tgbaalgos/dtbasat.cc, src/tgbaalgos/dtbasat.hh:
      (dtba_sat_minimize): Split into...
      (dtba_sat_synthetize, dtba_sat_minimize): These.
      (dtba_sat_minimize_dichotomy): New function.
      * src/tgbaalgos/dtgbasat.cc, src/tgbaalgos/dtgbasat.hh
      (dtgba_sat_minimize, dtgba_sat_synthetize): Likewise.
      * src/tgbatest/ltl2tgba.cc: Adjust to new interface.
      * src/tgbaalgos/postproc.cc, src/tgbaalgos/postproc.hh:
      Cleanup option processing for SAT options.
      * src/tgbatest/satmin.test: Adjust.

      sat: improve our algorithms · bcd794c6
      Alexandre Duret-Lutz authored
      * src/tgbaalgos/dtbasat.cc, src/tgbaalgos/dtbasat.hh:
      Rename dba_sat_minimize to dtba_sat_minimize.
      Make it possible to produce state-based automata, and do
      not output useless clauses.
      * src/tgbaalgos/dtgbasat.cc, src/tgbaalgos/dtgbasat.hh:
      likewise, but also add the possibility to set the
      target number of states, as in dtba_sat_minimize.
      * src/tgbaalgos/postproc.cc, src/tgbaalgos/postproc.hh:
      Add new options for state-based computations and
      setting acceptance and states number when using
      dtgba_sat_minimize().
      * src/tgbatest/ltl2tgba.cc: Adjust calls to
      dtba_sat_minimize().
      * src/tgbatest/satmin.test: Adjust calls.

      satsolver: new function · 3b10bb3b
      Alexandre Duret-Lutz authored
      Uses the value of the SPOT_SATSOLVER environment variable
      to decide how to call the SAT solver.
      
      * src/misc/satsolver.cc, src/misc/satsolver.hh: New files.
      * src/misc/Makefile.am: Add them.
      * src/tgbaalgos/dtbasat.cc, src/tgbaalgos/dtgbasat.cc: Use satsolver().
