Examples of 'recursively enumerable' in a sentence
Meaning of "recursively enumerable"
recursively enumerable - In computer science, this phrase is used to describe a set of elements or values that can be enumerated by an algorithm with the use of a computer program. It refers to a specific type of mathematical concept related to the theory of computation
