WebMar 12, 2024 · The formal definition of an NFA consists of a 5-tuple, in which order matters. Similar to a DFA, the formal definition of NFA is: (Q, 𝚺, δ, q0, F), where. Q is a finite set of all states. 𝚺 is a finite set of all symbols of the alphabet. δ: Q x 𝚺 → Q is the transition function from state to state. q0 ∈ Q is the start state, in ...

WebJan 23, 2015 · Given a complete DFA ( Q, A, δ, i, F) accepting the regular language L, the DFA ( Q, A, δ, i, Q − F) accepts the complement of L. This is still perfectly true if F = Q, in which case Q − F is empty. In other words, if you were assuming that the set of final states is nonempty, the previous proof would not work in all cases, which would be ...
