Dfa m induction proof

WebProof that M is correct (see homework solutions) can be simplified using structural induction. A proof by structural induction on the natural numbers as defined above is the same thing as a proof by weak induction. You must prove P(0) and also prove P ...

WebLet M be a DFA. 1. Since all DFA’s are PDA’s, M is a PDA. For all PDA’s M there exists CFL G such that L(M) = L(G). The drawback of this proof is that it requires PDA-to-CFG theorem. 2. For all DFA’s M there exists a regular expression α such that L(M) = L(α). By induction on the formation of a regular expression one can easily show ...
