How to draw dfa from regular expression. Web how would you draw a dfa for the language over {a,b,c} of all words where every occurrence of b is preceded and followed by a. Web the question is as follows: (regex => nfa => dfa) supported grammars r = (s) r = st r = s|t r = s* r = s+ r = s?

Web is there a systematic approach for simplifying regular expressions and deriving regular expressions from a given dfa, or vice versa, transforming regular. Web i recommend you first try to understand the language denoted by the regular expression. Web although there is no algorithmic shortcut to draw dfa from a regular expression (re) but a shortcut technique is possible by analysis not by derivation, it can.
