Undecidable — has more than one meaning:;In mathematical logic: * A decision problem is called (recursively) undecidable if no algorithm can decide it, such as for Turing s halting problem; see also under Decidable and Undecidable problem. * Undecidable is… … Wikipedia
Undecidable problem — In computability theory and computational complexity theory, an undecidable problem is a decision problem for which it is impossible to construct an algorithm that leads to a yes or no answer the problem is not decidable.A decision problem is any … Wikipedia
Recursion theory — Recursion theory, also called computability 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 to include the study of generalized computability… … Wikipedia
