WebLet us start by proving (by contradiction) that if is even then is even, as this is a result we will wish to use in the main proof. We do this by considering a number whose square, , is even, and assuming that this is not even. Then we try to arrive at a contradiction. If is not even, it is odd, and therefore of the form , where is a whole number. WebThen, we can construct a decider D TM for A TM: On input , run M H on . # If M H rejects, then REJ (this takes care of M looping on w) # If M H accepts, then simulate M on w until M halts # If M accepts, then ACC input ; else REJ L(D TM)=A TM ⇒A TM is decidable! Contradiction A H is undecidable R. Rao, CSE 322 6
WebSep 29, 2014 · Suppose the Turing machine M decided BTM. Define a Turing machine T that, on input x an encoding of a Turing machine, it computes the encoding y x of a Turing machine which runs the Turing machine encoded by x on input x; if M ( y x) = 1 then T gets into an infinite loop, and otherwise it halts.
