A NFA-based programmable regular expression match engine
Pattern matching is the most computation intensive task of a network intrusion detection system (NIDS). In this paper we present a hardware architecture to speed up the pattern mat...

The Inclusion Problem for Regular Expressions
This paper presents a new polynomial-time algorithm for the inclusion problem for certain pairs of regular expressions. The algorithm is not based on construction of finite automat...

Finite-State Registered Automata and Their Uses in Natural Languages
We extend finite state registered automata (FSRA) to account for medium-distance dependencies in natural languages. We provide an extended regular expression language whose expres...

On the Average Number of States of Partial Derivative Automata
The partial derivative automaton (Apd) is usually smaller than other non-deterministic finite automata constructed from a regular expression, and it can be seen as a quotient of th...
