seidel method meaning in Chinese

赛德尔方法

And then we bring forward an approach to get the probability of steady - state based on gauss - seidel method and dynamic row - column techniques for the application of simulation in safety " analysis , sampling techniques for sparse events are discussed , and importance sampling method is brought forward to increase sampling efficiency
论文提出了基于gauss - seidel方法与动态行列技术的分析方法。在仿真方面，主要探讨了安全性定量分析中稀有事件问题的抽样技术，并提出采用重要性抽样法，以提高抽样效率。
In this paper , we consider the optimal parameter vector a of the modified incomplete gauss _ seidel method ( migs ) . we prove that the spectral radius function of the iterative matrix t of migs with parameter vector is strictly monotonic decreasing with respect to a satisfying 0 e if the classical gauss _ seidel method converges for a z _ matrix . some properties of the left and right eigenvectors corresponding to the largest eigenvalue in modulus are given , too . these results are useful to find an optimal parameter for migs
目前主要的方法有两类：一是充分利用所给矩阵a的特点，采用适当的主元素选取策略，使分解出的因子尽可能地保持稀疏性；二是迭代法。对于第二种方法，迭代矩阵的选取具有决定作用。只有选取的迭代矩阵的谱半径小于1才能保证迭代法收敛。
