bool is_inherently_weak_automaton(const const_twa_graph_ptr &aut, scc_info *sm=nullptr)
Check whether an automaton is inherently weak.
twa_graph_ptr decompose_scc(const const_twa_graph_ptr &aut, const char *keep)
Extract a sub-automaton of a given strength.
bool is_very_weak_automaton(const const_twa_graph_ptr &aut, scc_info *sm=nullptr)
Check whether an automaton is very-weak.
bool is_terminal_automaton(const const_twa_graph_ptr &aut, scc_info *sm=nullptr)
