提出了一种基于生境人工鱼群算法的多峰问题优化算法．该算法融合了模拟退火、小生境技术的思想，并加入了变异算子和自动生成合适小生境半径机制-Since it is difficult to find all the optima when artificial fish SWalTn algorithm(AFSA)is used in multimodal

optimization．a niche artificial fish swalTn algorithm(NAFSA)based on basic AFSA is proposed．NAFSA combines the

niche technique and the simulated annealing method wim AFsA
