本文利用单纯形法局部搜索速度快和模拟退火算法全局寻优的特点,同时为了克服各自算法的弊病,提出采用单纯形—模拟退火混合算法(SMSA)进行水文地质逆问题的求解。论文详细描述了SMSA算法的具体操作算子的实现,并将该算法应用于一个大型水源地的地下水模拟反演。计算结果表明,SMSA算法在水文地质参数反演计算具有求解速度快,精度高的特点,而且易于实现并行运算。
In this paper, we use the local search speed of simplex method and the global optimization of simulated annealing algorithm. In order to overcome the shortcomings of each algorithm, this paper proposes the solution of hydrogeological inverse problem using the simplex - simulated annealing hybrid algorithm (SMSA). The dissertation describes the implementation of SMSA algorithm in detail and applies the algorithm to groundwater retrieval in a large water source. The calculation results show that the SMSA algorithm has the advantages of fast solution and high precision in the hydrogeological parameters inversion calculation, and it is easy to realize the parallel operation.
