- Recursive_languages_and_sets abstract "This article is a temporary experiment to see whether it is feasible and desirable to merge the articles Recursive set, Recursive language, Decidable language, Decidable problem and Undecidable problem. Input on how best to do this is very much welcome on the article's talk page. This is a work in progress so the current version may seem awkward.In computability theory, a set is decidable, computable, or recursive if there is an algorithm that terminates after a finite amount of time and correctly decides whether a given object belongs to the set. Decidability of a set is of particular interest when the set is viewed as a decision problem; a decidable set is also a decidable problem, computable problem, and recursive problem. The remainder of this article uses the term decidable, although recursive and computable are equivalent in this context. A language is a set of finite strings over a particular alphabet. A language is decidable (also computable, recursive) if it is a decidable set, that is, if there is a finite-time algorithm that can decide whether a given finite string is in the language.A set, language, or decision problem that is not decidable is undecidable, non-recursive, non-computable, or uncomputable. There are many known undecidable sets; one of the earliest, and most famous, examples is the halting problem.Decidable sets and languages are a strict subclass of the class of recursively enumerable sets. For those sets, it is only required that there is an algorithm that correctly decides when an input is in the set; the algorithm may fail to terminate for inputs not belonging to the set.".
