Abstract:Aiming at the deficiencies of current matching algorithm based on AIS (artificial immune system),proposed an improved evolution optimization with r-continuous bit matching rule.Gave the concepts and formal definitions of immune cells,presented affinity accumulation process. This new algorithm introduces evolution operator into the matching rule during the affinity accumulation process to improve the detection efficiency and overcome the short-coming of the local optimum. Theoretical analysis and experimental results show that the algorithm greatly enhances detection performance. ......
