求解对称鞍点问题的修正Uzawa方法

A CORRECTED UZAWA METHOD FOR SYMMETRIC SADDLE POINT PROBLEMS

本文基于两个非线性逼近逆的非线性Uzawa方法,给出了一种新的修正非线性Uzawa方法,并对其收敛性进行了分析以及与已有算法的收敛性进行了比较,最后由数值试验说明了算法的正确性和有效性。

In this paper we propose a new modified nonlinear Uzawa algothm based on a nonlinear Uzawa method of two nonlinear approximate inverses. A convergence analysis is given, which is compared with other Uzawa algorithms. Some numerical experiments are presented.
