      parseaut: preliminary support for reading alternating automata · e6203686
      Alexandre Duret-Lutz authored
      Currently this only reads universal branches.  The parser (and the
      automaton code) do not support universal initial states.
      
      * spot/parseaut/parseaut.yy: Read universal branches.  Deal with
      the no-univ-branch/!univ-branch change in HOA 1.1.
      * tests/python/alternating.py: Read the output of print_hoa.
      * tests/core/parseaut.test: Adjust test output, and add more tests.

      twa_graph: add basic support for alternation · 6aad559c
      Alexandre Duret-Lutz authored
      This only allows creating universal edges, and reading the associated
      destinations.
      
      * spot/twa/twagraph.hh (new_univ_edges, univ_dests, is_alternating): New
      function.
      * python/spot/impl.i: Add Python bindings.
      * tests/python/alternating.py: New file.

      graph: replace the existing "alternating" interface · 4903f086
      Alexandre Duret-Lutz authored
      * spot/graph/graph.hh: Use the sign bit of destination state X to
      designate a universal edge.  Store the destinations of such an edge in a
      separate array, at index ~X.
      * spot/graph/ngraph.hh, tests/core/graph.cc, tests/core/graph.test,
      tests/core/ngraph.cc: Adjust test case to the new interface.

      Add a new, parameterized, version of the Couvreur emptiness check. · 1a08eca8
      Maximilien Colange authored
      This version has optimization for explicit twa, and also for weak and
      terminal (depending on whether an accepting run is requested) automata.

      install back the safety check of includes.test · 7824005d
      Alexandre Duret-Lutz authored
      Compilation of each header file alone, as a safety check, was removed
      when introducing "#pragma once" because we did not have to check for
      possible double inclusion.  However we still need to compile each
      header to make sure they are self-contained.
