WebFeb 28, 2015 · Decidability of CFG ambiguity. I have been trying to show the following language is undecidable. L = { ( G , n): G is a context-free grammar with an ambiguous string of length ≤ n }. I think it is undecidable because if G doesn't have an ambiguous string, it seems like one would have to check parse trees of arbitrary heights to verify they ... WebPlease reduce from ATM, HALT or ALLcfg . Image transcription text. Show that each of the following languages is undecidable using reductions from known undecidable languages. (No points will be given for any other method of proof.) You may use as the source of the reduction any language shown in class or in the book to be undecidable.

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: WebApr 11, 2024 · BALTIMORE — Grammy-award-winning artist SZA is coming to Baltimore as a part of her S.O.S.
