摘要
将全局搜索能力强的差分进化算法与局部搜索能力强的单纯形算法结合起来,构成差分—单纯形算法。并将其应用于分析各向异性含水层抽水试验数据,确定各向异性条件下的含水层参数。数值试验结果表明,差分—单纯形算法能够有效地应用于求解各向异性含水层的抽水试验数据,确定各向异性含水层参数的函数优化问题。与其他方法相比较,具有计算精度高、运算速度快与实测数据拟合效果好等优点。
We have combined differential evolution algorithm which has a strong global search ability with simplex algorithm which has a strong local search ability, to form an differential-simplex algorithm. We applied this algorithm to analyze anisotropic aquifer pumping test data, to estimate the parameters under anisotropic aquifer. Numerical results showed that the difference-simplex algorithm could be effectively applied to analyze anisotropic aquifer pumping test data, to determine the function of the anisotropic aquifer parameters optimization problem. Compared with other methods, this method has high calculation precision, fast operation soeed and fits well with the measured results.
