WebRice's theorem says that for any subset F of the class T of partial computable functions, the set { i ∣ ϕ i ∈ F } is recursive iff F = ∅ or F = T. Let F be the set of partial computable functions that are constant on their domain. WebAug 5, 2024 · Proving Rice's theorem using Kleene's fixed point theorem. Ask Question.

Implications of Rice
WebJan 5, 2015 · Rice's theorem states that any nontrivial property P of a partial recursive function ψ e is undecidable (computably unsolvable by T e ). We take P to be decidable (either ψ e ( n) = 0 ∨ ψ e ( n) = 1 if P holds or does not hold, respectively). More directly, let 0 ′ be the degree of unsolvability of the problem for deciding if T e halts ... WebRice’s theorem, which shows that a very large class of di erent problems are undecidable.

proof of the rice
WebRice's theorem is very simple once the basics are understood, but it has little implications ... whatever you are trying to do, is my gut feeling. – Raphael ♦ Mar 3, 2015 at 7:35 Add a … WebProof of Rice’s Theorem Rice’s Theorem If P is a non-trivial property, then L P is undecidable. Proof. Suppose P non-trivial and ;62P. If ;2P, then in the following we will be showing L P is undecidable. Then L P = L P is also undecidable. Recall L P = fhMijL(M) satis es Pg. We’ll reduce A tm to L P. Then, since A tm is undecidable, L P ... WebRice's Theorem is a notorious stumbling block in Computer Science. We review some previous work of us that shows that we can extend Rice's result to large segments of … otro si contrato arrendamiento
