WebThe Church-Turing thesis is credible because every singe model of computation that anyone has come up with so far has been proven to be equivalent to turing machines … WebChurch-Turing Thesis (SCT), the widespread belief that Turing Machines (TMs) capture all computation, so models of computation more expressive than TMs are impossible. In this paper, we show that SCT reinterprets the original Church-Turing Thesis (CTT) in a way that Turing never intended; its commonly assumed equiva-lence to the original is a myth.
