Church turing theorem
Before the question could be answered, the notion of "algorithm" had to be formally defined. This was done by Alonzo Church in 1935 with the concept of "effective calculability" based on his λ-calculus, and by Alan Turing the next year with his concept of Turing machines. Turing immediately recognized that these are equivalent models of computation. The negative answer to the Entscheidungsproblem was then given by Alonzo Church in 1935–3… WebApr 11, 2024 · It is Church-Turing thesis is a thesis (and not a theorem) because we don't know if our understanding of the concept of mechanical process is right/wrong. $\endgroup$ – YOUSEFY Apr 11, 2024 at 22:12
