WebAnswer (1 of 3): The Church-Turing thesis is not a mathematical theorem but a philosophical claim about the expressive power of mathematical models of computation. The usual formulation of it is that no reasonable model of computation is more expressive than the Turing machine model. But what do... WebOct 18, 2024 · 2. I'm starting to study Turing machines, the Church-Turing conjecture and the circuit model. In particular, I'm interested in the proofs of universality that one can find in this context. So far, I have only found the universality proof of the circuit model for boolean functions (i.e., the gates AND, OR and NOT can be used to compute any ...
