A largest-distance pivot rule for the simplex algorithm
收藏 引用
EUROPEAN JOURNAL OF OPERATIONAL RESEARCH 2008年 第2期187卷 393-402页
作者: Pan, Ping-Qi SE Univ Dept Math Nanjing 210096 Peoples R China
We propose a new pivot rule for the simplex algorithm, which is demonstrative in the dual space intuitively. Although it is based on normalized reduced costs, like the steepest-edge rule and its variants, the rule is ... 详细信息

A revised dual projective pivot algorithm for linear programming
收藏 引用
SIAM JOURNAL ON OPTIMIZATION 2005年 第1期16卷 49-68页
作者: Pan, PQ Southeast Univ Dept Math Nanjing 210096 Peoples R China
We revise the dual projective pivot algorithm using sparse rectangular LU factors. In each iteration, the proposed algorithm solves at most three triangular systems, while simplex algorithms solve four. Instead of the... 详细信息

Robust reduction of a class of large-scale linear programs
收藏 引用
SIAM JOURNAL ON OPTIMIZATION 2001年 第1期12卷 262-282页
作者: Ioslovich, I Technion Israel Inst Technol Fac Agr Engn IL-32000 Haifa Israel
A set of new tests for linear programming presolving analysis is described. These tests are applicable for linear programs with box constraints and positive or zero coefficients. Partial applicability to general linea... 详细信息

A Log-Barrier method with Benders decomposition for solving two-stage stochastic linear programs
收藏 引用
MATHEMATICAL programming 2001年 第3期90卷 507-536页
作者: Zhao, GY Natl Univ Singapore Dept Math Singapore 119260 Singapore
An algorithm incorporating the Logarithmic barrier into the Benders decomposition technique is proposed for solving two-stage stochastic programs. Basic properties concerning the existence and uniqueness of the soluti... 详细信息

A fuzzy satisficing method for large-scale multiobjective linear programming problems with block angular structure
收藏 引用
FUZZY SETS AND SYSTEMS 1996年 第3期78卷 279-288页
作者: Sakawa, M Inuiguchi, M Sawada, K MATSUSHITEA ELECT WORKS LTD INFORMAT SYST CTROSAKA 571JAPAN
In this paper, we focus on large-scale multiobjective linear programming problems with the block angular structure. By considering the imprecise nature of human judgements, we assume that the decision maker may have a... 详细信息
