Description
After determinisation, the automaton may have no final state:
sage: A = Automaton([(0, 1, []), (1, 1, 0)], initial_states=[0], final_states=[1]) sage: A.transitions() [Transition from 0 to 1: -|-, Transition from 1 to 1: 0|-] sage: A.final_states() [1] sage: B = A.determinisation().relabeled() sage: B.initial_states() [0] sage: B.final_states() []
