Improvement of BM pattern matching algorithm

Shunli Ding

Open publisher page 1 citations

Abstract

Pattern matching algorithm is an important algorithm,used by most of Intrusion Detection System.On the base of analyzing BM algorithm and other algorithms,a new improved pattern matching algorithm—BMI algorithm is presented.The algorithm makes reference to the idea of BM algorithm and makes use of singleness and combination of the last character and next character of string,increasing the probability of maximum displacement effectively.Test results show that the algorithm can effectively improve the efficiency of the matching process.
