Primal simplex algorithm that solves the maximum flow problem in at most nm pivots and O(n2m) time
收藏 引用
mathematical programming, Series B 1990年 第3期47卷 353-365页
作者: Hao, Jianxiu Columbia Univ New York United States
We propose a primal network simplex algorithm for solving the maximum flow problem which chooses as the arc to enter the basis one that is closest to the source node from amongst all possible candidates. We prove that... 详细信息

Dantzig-wolfe-like variant of karmarkar's interior-point linear programming algorithm
收藏 引用
Operations Research 1990年 第6期38卷 1006-1018页
作者: Todd, Michael J.
We show that a variant of Karmarkar's projective algorithm for linear programming can be viewed as following the approach of Dantzig-Wolfe decomposition. At each iteration, the current primal feasible solution gen... 详细信息

Interior feasible direction method with constraint projections for linear programming
收藏 引用
Computers & mathematics with applications 1990年 第12期20卷 43-54页
作者: Synman, J.A. Univ of Pretoria Pretoria South Africa
A new feasible direction method for linear programming problems is presented. The method is not boundary following. The method proceeds from a feasible interior point in a direction that improves the objective functio... 详细信息

Karmarkar's algorithm with improved steps
Mathematical Programming, Series A
收藏 引用
mathematical programming, Series A 1990年 第1期46卷 73-78页
作者: Kalantari, B. Rutgers Univ United States
We define a function of the interior of the feasible region of Karmarkar's canonical linear program with the property that its supremum is bounded above by one, if and only if the optimal value of the linear progr... 详细信息

Extended Pareto optimality concept for multiobjective linear programming problems with fuzzy parameters and its properties
收藏 引用
Electronics and Communications in Japan, Part III: Fundamental Electronic Science (English translation of Denshi Tsushin Gakkai Ronbunshi) 1990年 第9期73卷 1-9页
作者: Sakawa, Masatoshi Takahashi, Junya Yano, Hitoshi Iwate Univ Morioka Japan
In order to handle multiobjective linear programming problems containing fuzzy parameters, the authors have already proposed four kinds of α-feasibility and β-Pareto optimality, based on the four kinds of index intr... 详细信息

Use of linear programming for the analysis of plane strain rigid-plastic flow
收藏 引用
International Journal for Numerical Methods in Engineering 1990年 第1期30卷 1-12页
作者: Pavier, M.J. Univ of Bristol United Kingdom
This paper describes an application of linear programming for the analysis of plane strain rigid-plastic flow. First, linear programming and the theory of a rigid-plastic material are briefly revised. The implementati... 详细信息

Unified approach top multiobjective linear programming problems with fuzzy parameters
收藏 引用
Electronics and Communications in Japan, Part III: Fundamental Electronic Science (English translation of Denshi Tsushin Gakkai Ronbunshi) 1990年 第5期73卷 19-28页
作者: Sakawa, Masatoshi Yano, Hitoshi Iwate Univ Japan
This paper considers multi-objective programming problems with fuzzy parameters, and newly defines the concepts of four types of α-feasibility and β-Pareto optimality. The relations between these concepts is discuss... 详细信息

Computational algorithm for solving 0-1 goal programming with GUB structures and its application for optimization problems in system reliability
收藏 引用
Electronics and Communications in Japan, Part III: Fundamental Electronic Science (English translation of Denshi Tsushin Gakkai Ronbunshi) 1990年 第12期73卷 88-96页
作者: Gen, Mitsuo Ida, Kenichi Lee, Jae-Uk Ashikaga Inst of Technology Ashikaga Japan
In this paper, we propose an efficient and specific algorithm for solving large-scale 0-1 GP problems in particular structures, which are termed GUB structures. Furthermore, to illustrate the effectiveness of the algo... 详细信息

Exponential example for Terlaky's pivoting rule for the criss-cross simplex method
Mathematical Programming, Series A
收藏 引用
mathematical programming, Series A 1990年 第1期46卷 79-84页
作者: Roos, C. Delft Univ of Technology Netherlands
Recently T. Terlaky has proposed a new pivoting rule for the criss-cross simplex method for linear programming and he proved that his rule is convergent. In this note we show that the required number of iterations may... 详细信息

One-phase algorithm for semi-infinite linear programming
Mathematical Programming, Series A
收藏 引用
mathematical programming, Series A 1990年 第1期46卷 85-103页
作者: Hu, Hui Stanford Univ United States
We present an algorithm for solving a large class of semi-infinite linear programming problems. We prove the convergence of this algorithm in two steps. First, we show that the algorithm can find an Ε-optimal solutio... 详细信息
