We consider the construction of finite automata from their corresponding regular expressions by a series of digraph-transformations along the expression’s structure. Each interm...
In this paper we investigate how it is possible to recover an automaton from a rational expression that has been computed from that automaton. The notion of derived term of an expr...

Abstract—Regular expression matching (REM) with nondeterministic finite automata (NFA) can be computationally expensive when a large number of patterns are matched concurrently....
