WebProof of the Rabin-Scott Theorem. We already saw in the last section that every language which can be recognized by a DFA can also be recognized by an NFA. To complete the proof of the Rabin-Scott Theorem, we need to establish the other, far less trivial, direction. Lemma. For every NFA N N, there is a DFA M M that recognizes L (N) L(N) .
