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). WebJFLAP is a tool to experiment with formal languages, grammars and parsing, including finite state machines, pushdown automata, Turing machines, LL and LR parsing, but also with proofs such as converting an NFA to a DFA to a min-state DFA to a regular expression or regular grammar. See the JFLAP website for more information.
