You can prove your DFA is minimal by proving that every state is both reachable and distinguishable. To prove a state st is reachable, you must give a word (a possibly empty sequence of symbols) that goes from the starting state ( q0 in your diagram) to state st. So for your diagram, you must give six words: one for each of q0, q1 ...

Webinduction on w . (This will become the base case of our second proof by induction) Base case: w = 0; that is, w = ε In problem 1(b), we constructed a DFA that recognizes the language that contains only the empty string, and thus this language is regular. Induction: Let L be a language that recognizes a single string w over Σ. WebSep 15, 2015 · (Judging by your question, this might even have been what you were actually thinking.) What you’ve already proved therefore shows that every DFA can be converted to an NFA with a single acceptor state, but it doesn’t prove that every DFA can be converted to a DFA with a single acceptor state. And in fact that statement isn’t true.
