Abstract: For complex functions with high dimensions，a new chaotic mutation differential evolution algorithm（CNDE） combined with niche is presented.Niching methods are introduced to improve the effective and independent searching.And chaotic mutation，which behaves well in local searching，is improved in this paper.In order to balance global and local search ability，convergence speed is fastened，and premature is avoided.The cross rate is automatically updated according to the generation.The experimental results show that the new algorithm not only has great advantage of convergence，but also can avoid the premature convergence problem effectively.
