Research on Evolving Control Parameters in Niche Genetic Algorithm

Niche genetic algorithm is superior to genetic in multiple hump function optimization.However,there is lack of theory to determine the parameter of niche distance,so the algorithm’s application is limited.This paper presents a new approach to determine the niche distance parameter,which is based on genetic algorithm.According to the information of multiple hump object function,genetic algorithm is used to seek several global optimums,whose Euclidean distances are calculated.The niche distance is determined by the minimal Euclidean distance.This approach is successfully used in Shubert function optimization and six-hump camel back function optimization.
