A (finite non-deterministic) automaton is a quintuple M = (Q,Act,q0,F,T), where:
- Q is the set of states
- Act is the set of actions
- q0 is the starting state
- F is the set of final states
- T is the transition relation (T ⊆ Q × Act × Q)
Automata Behaviour: language equivalence
(where L(M) is the set of all the sequences of input characters that bring the automaton M from its starting state to a final one)
>[!note]
>M1 and M2 are *language equivalent* if and only if L(M1)=L(M2)
