WebHere is the version of Rice's theorem I use: Rice's first Theorem: For every non-trivial, language invariant property P of a set of Turing machines it holds that the set. { M P ( M) } is undecidable. One of the major problems seems to be that A T M is not a set of Turing machines -but rather encoded couples of Turing machines and strings ...

WebAlternative Proof Technique for Undecidability. We can use Rice’s Theorem to directly prove that a language is undecidable by showing that the language fulfills the two conditions of the theorem. Claim: E TM = { M ∣ M is a TM and L ( M) = ∅ } is undecidable. Proof. By Rice’s theorem, we must show that E T M satisfies two properties: Non ... examples of adobe animateWebProof 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.

We take P to be decidable (either ψ e ( n) = 0 ∨ ψ e ( n) = 1 if P holds or does not hold, respectively).
