Juan Zhang · China Rural Water and Hydropower · 2005
The problem of hydrogeological parameters identification is actually a complex nonlinear program. With the limit of the slow convergence of the standard simulationannealing algorithm, a modified simulationannealing algorithm for the identification of hydrogeological parameters is proposed in this paper. Some strategies such as adding supplement constraint to the variables, setting up inner valve value and adding memory function in the inner loops are taken to quicken the convergence of the standard simulation anneal algorithm. Application of the method in practice shows that the proposed method is applicable to hydrogeological parameter and aquifer impervious boundary identifications with high accuracy. Additionally, several factors affecting the convergence of the algorithm are analyzed in the case study.
