WebThe Universal Turing Machine • Using the Turing Machine, Turing showed that not all problems are solvable (there is no machine that can determine whether an arbitrary given proposition is true or false). • Turing showed there is a Universal Turing machine (UTM) that can imitate any other Turing machine. In the UTM, we first encode the description of … In computability theory, the Church–Turing thesis (also known as computability thesis, the Turing–Church thesis, the Church–Turing conjecture, Church's thesis, Church's conjecture, and Turing's thesis) is a thesis about the nature of computable functions. It states that a function on the natural numbers can be calculated by an effective method if and only if it is computable by a Turing machine. The thesis is named after American mathematician Alonzo Church and the British math…
