摘要
针对传统数值算法求解非线性规划问题的局部搜索性及对初值敏感性强等缺陷,引进了一种全局搜索算法——杂交差分进化方法,并对算法做了局部改进,在约束条件的处理上采取了动态改变惩罚力度的方法,提高了种群多样性,又保证收敛到全局最优解.实际算例说明了该方法的有效性.
Owing to higher probability of obtaining a local minimum and sensitivity to the initial value, it is difficult to salve the mathematical model of products methods. The hybrid differential evolution algorithm is pipeline optimal design using conventional numerical introduced to deal with it and the methodology dynami- cally handling constraints in the evolutionary process is developed. The population variety and the convergence are then improved. A real example was tested and a satisfactory solution was obtained, which proves the effectiveness of this method.
