Allcfg
WebALLCFG = {〈G〉 G is a CFG and L (G) = Σ∗}. EQCFG = {〈G1, G2〉 G1, G2 are CFGs and L (G1) = L (G2)}. ALLCFG is undecidable (you don’t have to show this). EQCFG is undecidable (you will show this in the second part of the problem). (a) (3 points) Can Rices Theorem be applied to argue that EQCFG undecidable? Give a brief explanation for your … WebTo prove that ALLCFG ≤m EQCFG, we need to show that there is a computable function f such that for every context-free grammar G, f(G) is a context-free grammar equivalent to G. We can define f as follows: Given a context-free grammar G = (V, Σ, R, S), we construct a new context-free grammar G' = (V', Σ', R', S') as follows:
