An Optimal Construction of Finite Automata from Regular Expressions
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...

How Expressions Can Code for Automata
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...

Evaluating Linear XPath Expressions by Pattern-Matching Automata
: We consider the problem of efficiently evaluating a large number of XPath expressions, especially in the case when they define subscriber profiles for filtering of XML documen...

Space-time tradeoff in regular expression matching with semi-deterministic finite automata
Abstract—Regular expression matching (REM) with nondeterministic finite automata (NFA) can be computationally expensive when a large number of patterns are matched concurrently....
