摘要: 为了解决de Castro在2000年提出的CLONALG算法在多峰值函数优化时多峰搜索能力弱,训练时间长的问题,提出自适应小生境克隆选择算法(ANCSA)。该算法运用自适应小生镜技术、高频变异算子和小生镜免疫优势选择技术来对原有算法进行改进。新算法具有较强的全局和局部搜索能力,并且搜索时间较短。理论分析和仿真研究结果表明,相比CLONALG算法,提出的算法能够在较短的时间内搜索到所有的全局最优解和更多的局部最优解。

Abstract: In order to solve the drawbacks of the CLONALG algorithm for multi-modal function optimization developed by de Castro in 2000,an Adaptive Niche Clonal Selection Algorithm(ANCSA) is proposed.The new algorithm,which uses adaptive niche technology,high-frequency mutation operator and the niche immunodominance selection,is much strong in global and local search capabilities,and is relatively short in search time.Theoretical analysis and the simulation study results show the proposed algorithm can find the global optimum solution and more local optimum solution in shorter time compared with the CLONALG algorithm.
