WebDefinition of Church Turing Thesis. Church Turing Thesis states that: A computation process that can be represented by an algorithm can be converted to a Turing Machine. … 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…
