Fast Mutation Operator Applied in Detector Generating Strategy

Inspired by the stimulated-responding mutation process of gene segment, a new mutation operator is proposed. The main characteristic is its mutation method, when one bit is mutated then the following contiguous bits are to be mutated according to the mutated, which make it owns better capability of local search. At the same time a new algorithm, named Contiguous somatic stimulated mutation algorithm (CSSMA), is given based on the novel mutation operator. Experiments showed, the CSSMA outperforms than some classical algorithms in term of the detective rate and time cost.
