WebEquivalence between Regular Expressions and Finite Automata Theorem A language is regular if and only if some regular expression describes it. I That is, a language L is regular if and only if there exists a regular expression R such that L(R) = L. I Note that the theorem is a biconditional statement, and so to prove it, both directions must be ...
WebI have a regular grammar that looks like: And I need to convert that to a regular expression. The issue I'm having is the problem asks me to eliminate S, then A, then B (in that order). However, I'm not quite sure how to eliminate S first as I end up with a couple productions that don't have any connections (might not be the right word).
