Shanks and Anderson-type acceleration techniques for systems of nonlinear equations

Claude Brezinski, Stefano Cipolla, Michela Redivo-Zaglia, Yousef Saad

摘要:

本文研究了一些外推和加速方法,并介绍了一些修改的标准的Shanks变换,处理一般的序列。本文的目标之一是制定一个包含大多数已知加速策略的总体框架。本文还考虑了安德森加速法在一个新的光和开发的连接与拟牛顿法,以建立局部线性收敛结果的稳定版本的安德森加速法。测试的方法上的一些问题,包括一些产生的非线性偏微分方程。

英文摘要:

This paper examines a number of extrapolation and acceleration methods, and introduces a few modifications of the standard Shanks transformation that deal with general sequences. One of the goals of the paper is to lay out a general framework that encompasses most of the known acceleration strategies. The paper also considers the Anderson Acceleration method under a new light and exploits a connection with quasi-Newton methods, in order to establish local linear convergence results of a stabilized version of Anderson Acceleration method. The methods are tested on a number of problems, including a few that arise from nonlinear Partial Differential Equations.
