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 21, 2024 · 2 Answers. 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.

WebFirst we are going to prove by induction on strings that 1 * ( q 1,0, w ) = 2 * ( q 2,0, w ) for any string w. When it is proven, it obviously implies that NFA M 1 and DFA M 2 accept the same strings. Theorem: For any string w, 1 * ( q 1,0, w ) = 2 * ( q 2,0, w ) . Proof: This is going to be proven by induction on w. Basis Step: For w = , Web3.1. DETERMINISTIC FINITE AUTOMATA (DFA’S) 53 3.1 Deterministic Finite Automata (DFA’s) First we deﬁne what DFA’s are, and then we explain how they are used to accept or reject strings.
