Abstract:: The approximate calculation of the abnormal integral of the singularity on the vertex of the rectangular domain and the optimization center numerical algorithm are given, which avoids a large number of repeated calculations of function values, uses the extrapolation method to reduce the number of iterations, and can reach the approximate value that meets the accuracy requirements as soon as possible, and the proposed optimized numerical algorithm is convenient for calculation on the computer.
