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 = , WebI understand mathematical induction, however when strings come into play I get real tripped up.

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 ...
