WebJul 30, 2014 · Let's assume that \mathcal {L}_\forall L∀ is recognizable, and a Turing machine T T recognizes it. This means for any Turing machine M M that accepts all strings, T (\langle M\rangle ) T ( M ) will halt eventually in an ACCEPT state. Conversely, if T (\langle M\rangle ) T ( M ) either does not halt, or halts in a REJECT state, it means M M ... WebThe ETM file extension indicates to your device which app can open the file.

WebTheorem. ETM = {hMi M is a TM and L(M) = ∅} is undecidable. Proof. We show ATM is reducible to ETM. First, given hM,wi, a Turing machine can modify the encoding of M, to transform M into M′, which recognises L(M)∩{w}. This is what the new machine M′ does on input x: 1. If x 6= w, reject. 2. If x = w, run M on w and accept if M accepts.
