Halttm
WebHALTTM = { M is a TM and halts on w} is also undecidable. Goal: If we can reduce ATM to HALTTM, then HALTTM is undecidable as well. Assume a TM exists that decides HALTTM, call this R. Produce S: a machine that decides ATM. S has input (M, w) 1). Call R(M, w) 2). If R rejects, reject (because we know that w ( L(M)) else WebAdvanced Math questions and answers.

WebQuestion: 1. (3, 1, 1 points) In class, we learned that Ap is non-TR, ATM and HALTTM are TR but non-TD. What can you say about their complements? Circle or check the correct answers below. WebA = { (M) M is a Turing machine that halts on input } We'll use the fact that HALTTM is undecidable. 1. First create a Turing machine M, that halts on & iff M halts on w, where (M,w) is the input to HALTTM. The input to My will be any string 1. The behavior of M, will depend on M's behavior of input w.
