水文地质参数识别的快速和谐搜索算法

Fast harmony search algorithm and its application to hydrogeological parameters identification

摘要: 将一种新的启发式和谐搜索算法(harmony search algorithm,HS)引入到水文地质领域。在对其音节调整步骤进行改进的基础上,提出快速和谐搜索算法(Fast harmony search algorithm,FHS),并将FHS算法与MODFLOW结合,用于水文地质问题的参数识别。算例研究表明,FHS算法较其他多种算法具有更强的全局搜索能力、更快的收敛速度及求解精度,可用于地下水数值模型的参数反演。

Abstract: In this article a new metaheuristic algorithm-harmony search algorithm(HS) is introduced into hydrogeological fields.Based on the improvement of the pitch adjustment step,we firstly put forward the fast harmony search algorithm(FHS).The proposed method greatly enhances the efficiency of the algorithm and accuracy of the solution.FHS is combined with MODFLOW to solve the problem of hydrogeological parameters identification.Examples of studies have shown that FHS algorithm has a strong global sear...
