WebConverting regular expressions into (minimal) NFA that accept the same language is easy with standard algorithms, e.g. Thompson's algorithm. The other direction seems to be more tedious, though, and sometimes the resulting expressions are messy. What algorithms are there for converting NFA into equivalent regular expressions?

Convert simple regular expressions to deterministic finite automaton. (Regex => NFA => DFA) 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). how to replace regular outlet to gfi
