WebLet’s call the DFA associated with the above transition diagram A. We have to prove that L(A) = L. Proof. In order to prove L(A) = L, we just need to prove the following state invarance. (even;s) = 8 <: even if s contains even number of a’s odd if s contains odd number of a’s We will prove this by induction on jsj. Web1. The following DFA recognizes the language containing either the substring 101 or 010. I need to prove this by using induction. So far, I have managed to split each state up was follows: q0: Nothing has been input yet. q1: The last letter was a 1 and the last two characters were not 01. q2: The last letter was a 0 with the letter before that a 1. 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.

(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.

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 = , Websome DFA if and only if Lis accepted by some NFA. Proof: The \ if" part is Theorem 2.11.
