Recognition problem, Theory of Computation

Assignment Help:

The Recognition Problem for a class of languages is the question of whether a given string is a member of a given language. An instance consists of a string and a (?nite) speci?cation of the language. Again, we'll assume we are given a DFA as a ?ve-tuple.

Theorem 3 (Recognition) The Recognition Problem for Regular Languages is decidable.
