An Optimal Construction of Finite Automata from Regular Expressions

pdf-format:
Dokument 1.pdf (444 KB)


Abstract

We consider the construction of finite automata from their corresponding regular expressions by a series of digraph-transformations along the expression\'s structure. Each intermediate graph represents an extended finite automaton accepting the same language. The character of our construction allows a fine-grained analysis of the emerging automaton\'s size, eventually leading to an optimality result.
