WebLimits of Turing Machines •Church-Turing thesis : Anything that can be programmed can be programmed on a TM •Not all languages are Turing Decidable! –A TM = {, M is a description of a Turing Machine T M, w is a description of an input and T M accepts w} •We shall see this in Chapter 4 •A TM is not even Turing-recognizable! 10/8/20 WebThe Church–Turing thesis states that any "computable" function that can be computed by a mathematician with a pen and paper using a finite set of simple algorithms, can be computed by a Turing machine. Hypercomputers compute functions that a Turing machine cannot and which are, hence, not computable in the Church–Turing sense.
