Abstract: Negative selection algorithm is one of the traditional core algorithms of the artificial immune system, many improved algorithms are based on it, However, there are many problems about these algorithm such as the long-time computing and the excessive consumption of space resources. In order to reduce the complexity of the algorithm and the generation time of the detector, we presented a algorithm which was based on the niche strategy, it improve the efficiency of the generation of negative selection algorithm.
