(definition)
Definition: A language for which membership can be decided by an algorithm that halts on all inputs in a finite number of steps --- equivalently, can be recognized by a Turing machine that halts for all inputs.
Also known as recursive language, totally decidable language.
See also undecidable language, decidable problem, recursively enumerable language.
Note: For emphasis, the equivalent term totally decidable language is sometimes used. From Algorithms and Theory of Computation Handbook, page 24-19, Copyright © 1999 by CRC Press LLC. Appearing in the Dictionary of Computer Science, Engineering and Technology, Copyright © 2000 CRC Press LLC.
