WebGiven an instance (M,x) of the halting problem, construct a new machine M′ that works as follows: on inputs of length n, it simulates M on x for f(n) steps or until M halts, where f(n) is any arbitrary increasing function (greater than constant) of n. " of another program P, and an input string S, prints "Halts" if P(S) eventually halts, and prints "Loops" if P(S) loops forever. Turing showed that the answer is no: there is no computable halting oracle.

WebComputability is the ability to solve a problem in an effective manner. It is a key topic of the field of computability theory within mathematical logic and the theory of computation within computer science.The computability of a problem is closely linked to the existence of an algorithm to solve the problem.. The most widely studied models of computability are … Many variants of the halting problem can be found in computability textbooks. Typically, these problems are RE-complete and describe sets of complexity in the arithmetical hierarchy, the same as the standard halting problem. The variants are thus undecidable, and the standard halting problem reduces to each variant and vice-versa. However, some variants have a higher degree of unsolvability and cannot be reduced to the standard halting problem.

"A machine with an oracle for the halting problem can determine whether particular Turing machines will halt on particular inputs, but it cannot determine, in general, whether machines equivalent to itself will halt. This creates a hierarchy of machines, each with a more powerful halting oracle and an even harder halting problem. This hierarchy of machines can be used to define the arithmetical hierarchy (Börger 1989). " - Halting oracle
