Globally and superlinearly convergent algorithm for minimizing a normal merit function
收藏 引用
SIAM JOURNAL ON CONTROL AND OPTIMIZATION 1998年 第3期36卷 1005-1019页
作者: Polak, E Qi, LQ Univ Calif Berkeley Dept Elect Engn Berkeley CA 94720 USA Univ New S Wales Sch Math Sydney NSW 2052 Australia
In this paper we present two new concepts related to the solution of systems of nonsmooth equations (NE) and variational inequalities (VI). The first concept is that of a normal merit function, which summarizes the si... 详细信息

Bregman primal-dual first-order method and application to sparse semidefinite programming
收藏 引用
COMPUTATIONAL OPTIMIZATION AND APPLICATIONS 2022年 第1期81卷 127-159页
作者: Jiang, Xin Vandenberghe, Lieven Univ Calif Los Angeles Elect & Comp Engn Los Angeles CA 90095 USA
We present a new variant of the Chambolle-Pock primal-dual algorithm with Bregman distances, analyze its convergence, and apply it to the centering problem in sparse semidefinite programming. The novelty in the method... 详细信息

A fixed-point augmented Lagrangian method for total variation minimization problems
收藏 引用
JOURNAL OF VISUAL COMMUNICATION AND IMAGE REPRESENTATION 2013年 第7期24卷 1168-1181页
作者: Duan, Yuping Huang, Weimin ASTAR Inst Infocomm Res Singapore Singapore
In this paper, we propose a fixed-point augmented Lagrangian method (FPALM) for general convex problems arising in image processing. We can easily obtain the alternating minimization algorithm (AMA) referred to [1] fr... 详细信息
