| 摘 要： | 提出了一种改进的差异演化算法MDE(modified differential evolution algorithm),该算法首先对差异演化算法的缩放因子进行混沌计算,减少了用户参与程度,平衡了算法的收敛速度与全局搜索能力;其次引入灾变因子,对群体中的个体进行小概率淘汰,同时又有新的个体加入,从而提高了群体多样性,提高了算法的全局搜索能力.仿真实验与工程实例表明,该算法具有较好的全局搜索能力.

| Abstract: | Differential evolution(DE) is one kind of evolution algorithm based on difference of individuals.DE has exhibited good performance on optimization.However,for the high dimension and perplexed function,the algorithm is apt to fall into premature convergence,its performance is strongly influenced by the value of each strategy parameter including scale factor.Therefore,a modified differential evolution algorithm(MDE) was proposed to solve the optimization problems.First,the scale factor was randomly initialize... |
