      alternation: implement remove_alternation() for weak alt automata · fa06cfa3
      Alexandre Duret-Lutz authored
      This mixes the subset construction (for 1-state rejecting SCCs) and
      the breakpoint construction (for larger rejecting SCCs).  The
      algorithm should probably be rewritten in a cleaner and more efficient
      way, but that should do for a first version.  It should be easy to
      extend it to support Büchi acceptance (since the breakpoint
      construction works for this) when we need it.
