Regular Expressions with Lookahead

This paper investigates regular expressions which Honda GPS Antenna Adapter in addition to the standard operators of union, concatenation, and Kleene star, have lookaheads.We show how to translate regular expressions with lookaheads (REwLA) to equivalent Boolean automata having at most 3 states more than the length of the REwLA.We Heart Bracelet_Chloe also investigate the state complexity when translating REwLA to equivalent deterministic finite automata (DFA).
