Automata Theory Questions
A recursively enumerable language is a type of formal language in automata theory that can be recognized by a Turing machine. It is a language for which there exists a Turing machine that will eventually halt and accept any string that belongs to the language, but may either halt and reject or loop indefinitely for strings that do not belong to the language. In other words, a recursively enumerable language is a language that can be enumerated by a Turing machine, where the machine will eventually generate all the strings in the language, but may not halt for strings that are not in the language.
