Interior proximal Method Without the Cutting Plane Property
收藏 引用
JOURNAL OF OPTIMIZATION THEORY AND APPLICATIONS 2015年 第2期166卷 529-557页
作者: Langenberg, Nils Univ Trier D-54286 Trier Germany
A new interior proximal method for variational inequalities with generalized monotone operators is developed. It transforms a given variational inequality (which, maybe, is constrained and ill-posed) into unconstraine... 详细信息

FIXED point THEORY AND APPLICATIONS 2015年 第1期2015卷 1-23页
作者: Chuang, Chih Sheng Yu, Zenn-Tsun Lin, Lai-Jiu Natl Sun Yat Sen Univ Dept Appl Math Kaohsiung 700 Taiwan Nan Kai Univ Technol Dept Elect Engn Nantou 542 Taiwan Natl Changhua Univ Educ Dept Math Changhua 50058 Taiwan
In this paper, two iteration processes are used to find the solutions of the mathematical programming for the sum of two convex functions. In infinite Hilbert space, we establish two strong convergence theorems as reg... 详细信息

OPTIMIZATION 2015年 第10期64卷 2145-2161页
作者: Langenberg, Nils Univ Trier Fachbereich 4 Abt Math Trier Germany
The Bregman function-based proximal point algorithm (BPPA) is an efficient tool for solving equilibrium problems and fixed-point problems. Extending rather classical proximal regularization methods, the main additiona... 详细信息

A note on a paper "A regularization method for the proximal point algorithm"
收藏 引用
JOURNAL OF GLOBAL OPTIMIZATION 2009年 第1期43卷 171-174页
