详细信息   
摘要
///In this paper, a new metaheuristic algorithm-harmony search algorithm (HS) is introduced into hydrogeological fields. Based on the improvement of the pitch adjustment step, the authors firstly put forward the fast harmony search algorithm (FHS). The 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. The results show that FHS algorithm has a strong global search ability and fast convergence rate for solving the problems of complex groundwater model parameter identification. In comparison with three other algorithms, namely simple genetic algorithm (SGA), particle swarm optimization (PSO) and improved harmony search (IHS), FHS presented in this paper can provide reliable hydrogeological parameters for numerical groundwater models.
