Dfa induction
Websome DFA if and only if Lis accepted by some NFA. Proof: The \ if" part is Theorem 2.11. For the \ only. if" part we note that any DFA can be converted to an equivalent NFA by mod-ifying the D. to N. by the rule If D (q;a) = p, then N (q;a) = fpg. By induction on jwjit will be shown in the tutorial that if ^ D (q. 0;w) = p, then ^ N (q. 0;w) = fpg. WebApr 24, 2024 · This video proves the correctness of the very simple on-off switch from the previous video using weak mutual induction.
