WebApr 28, 2015 · So I can start with "babb" which your DFA accepts, having odd number of b's and odd number of a's. q0->q1->q2 is a cycle of 3 a's so adding 3 a's when I am in one of those states does not change wether the automata accepts, so your automata accepts "aaababb" despite neither having an odd number of a's or an even number of b's. WebDesign FA with ∑ = {0, 1} accepts even number of 0's and even number of 1's. Solution: This FA will consider four different stages for input 0 and input 1.

It is an easy induction on w to show that dh(A,w) = A if and only if w has an even number of 1's. Basis: w = 0. Then w, the empty string surely has an even number of 1's, namely zero 1's, and δ-hat(A,w) = A.
