摘要
本文在多重网格法Gauss-Seidel型插值算子的基础上,再用Jacobi松弛予以修正得到高精度算法,多重网格法的两层收敛性也获得了证明,数值例子进一步证实了新算法的效率。
In this paper, based on Gauss-Seidel-type interpolation operator, an improved MG algorithm with high accuracy is obtained by performing Jacobi relaxation. We prove the two-level convergence of new MG method, and numerical examples further demonstrate the efficiency of new algorithm.
