http://infolab.stanford.edu/~ullman/ialc/spr10/slides/fa2.pdf 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).

WebTheorem 1.1. Regular expression is equivalent to NFA with ϵ-moves (and thus equivalent to DFA, NFA). Proof. (Regular expression ⇒ NFA with ϵ-moves) We will prove, if L is accepted by a regular expression, then there exists an NFA with ϵ-moves M such that L = L(M). Basis: if r = ∅, let M be an NFA with only initial state (no nal state); if r = ϵ, let M be an NFA with … WebThus, to prove some property by induction, it su ces to prove p(a) for some value of a and then to prove the general rule 8k[p(k) !p(k + 1)].
