| 摘 要： | 为改善遗传算法局部寻优精度较差的固有缺陷,该文引入一种新的基于遗传算法的模式搜索法求解地下水管理模型.首先通过在遗传算法中引入精英保留的进化策略,提高遗传算法的收敛性,进行全局搜索得到全局近似最优解,在此基础上采用局部寻优类算法模式搜索法进一步改善优化结果,最后将该混合优化方法用于求解一个地下水管理的基准问题.计算结果...

| Abstract: | In order to overcome the inherent disadvantage of the genetic algorithm,an improved hybrid optimization method was introduced to solve groundwater management models.The improved hybrid method was based on genetic algorithm and a local search algorithm named pattern search method.Firstly,the elitist strategy was introduced into GA to improve the global convergence,and an approximate global optimal solution was obtained;secondly,the pattern search method was utilized for further improving the approximate glob... |
