This version has optimization for explicit twa, and also for weak and terminal (depending on whether an accepting run is requested) automata. * spot/twaalgos/couvreurnew.hh, spot/twaalgos/couvreurnew.cc, spot/twaalgos/Makefile.am: New files for the new algorithm. * spot/twaalgos/emptiness.cc, tests/core/randtgba.cc: Register new algorithm.
