Determination of the acceleration factor in groundwater simulation process through BP algorithm
基于BP算法的地下水模拟中加速因子的确定

In applying the successive over-relaxation iteration method to solve large-scale linear equations,one often has difficulties in determining the acceleration factor.Through training and learning using BP neural network and comparative analyses, we obtained a good model,which could be used for fast determination of the acceleration factor.We used it in the Luancheng hydrology experimental base in Shijiazhuang,and the results show that BP artificial neural network has been successfully used in solving the difficult problem, determination of the acceleration factor in the groundwater numerical simulation process.
