Research Abstract

Below are results obtained by this research project.
1. We developed an extended regular expression matching algorithm based on finite automata.
2. We developed a hybrid extended regular expression matching algorithm based on finite automata. This algorithm can make use of various automata.
3. We extended the above algorithm to an extended regular expression with any boolean function.
4. We made searching soft-wares for the algorithms developed and evaluated the performance experimentally.
5. We developed an approximate matching algorithm for semi-extended regular expressions.
6. We developed an efficient translation algorithm from regular expressions into NFAs. This algorithm can be used in matching algorithms.
