**Post–Turing machine**— The article Turing machine gives a general introduction to Turing machines, while this article covers a specific class of Turing machines. A Post–Turing machine is a program formulation of an especially simple type of Turing machine, comprising a … Wikipedia**Computability theory**— For the concept of computability, see Computability. Computability theory, also called recursion theory, is a branch of mathematical logic that originated in the 1930s with the study of computable functions and Turing degrees. The field has grown … Wikipedia**Turing machine**— For the test of artificial intelligence, see Turing test. For the instrumental rock band, see Turing Machine (band).

In computability theory, a system of data manipulation rules (such as an instruction set, a programming language, or a cellular… … Wikipedia**Turing degree**— Post s problem redirects here. For the other Post s problem , see Post s correspondence problem. In computer science and mathematical logic the Turing degree or degree of unsolvability of a set of natural numbers measures the level of algorithmic … Wikipedia**Turing reduction**— In computability theory, a Turing reduction from a problem A to a problem B, named after Alan Turing, is a reduction which solves A, assuming B is already known (Rogers 1967, Soare 1987). It can be understood as an algorithm that could be used to … Wikipedia**Post's theorem**— In computability theory Post s theorem, named after Emil Post, describes the connection between the arithmetical hierarchy and the Turing degrees. Background The statement of Post s theorem requires several concepts relating to definability and… … Wikipedia**Turing jump**— In computability theory, the Turing jump or Turing jump operator, named for Alan Turing, is intuitively described as an operation that assigns to each decision problem X a successively harder decision problem X prime; with the property that X… … Wikipedia**Post correspondence problem**— The Post correspondence problem is an undecidable decision problem that was introduced by Emil Post in 1946.[1] Because it is simpler than the halting problem and the Entscheidungsproblem it is often used in proofs of undecidability.
