چکیده

A New Family of Valid-Inequalities for Dantzig-Wolfe Reformulation Mixed Integer Linear Programs In “Consistency Cuts Reformulation,” Jens Vinther Clausen, Richard Lusby, and Stefan Ropke present a new family valid inequalities to be applied reformulations with binary linking variables. They show that, mixed integer linear programs that satisfy certain properties, it is enough solve the programming relaxation reformulation all consistency cuts obtain solutions. An example this temporal knapsack problem; effectiveness tested on set 200 instances problem, results are state-of-the-art solution times. For problems do not these conditions, can still used in branch-and-cut-and-price framework. order this, generic from online library MIPLIB. These tests applicability general.

Dantzig-Wolfe Reformulations for the Stable Set Problem

Dantzig-Wolfe reformulation of an integer program convexifies a subset of the constraints, which yields an extended formulation with a potentially stronger linear programming (LP) relaxation than the original formulation. This paper is part of an endeavor to understand the strength of such a reformulation in general. We investigate the strength of Dantzig-Wolfe reformulations of the classical e...

Mechanism Design via Dantzig-Wolfe Decomposition

In random allocation rules, typically first an optimal fractional point is calculated via solving a linear program. Lying in the feasible region of the linear program, the fractional point satisfies the underlying constraints. In effect, the point represents a fractional assignment of objects or more generally packages of objects to agents. In order to implement an expected assignment, one must...

A stabilized structured Dantzig-Wolfe decomposition method

We present an algorithmic scheme, which we call the Structured Dantzig-Wolfe decomposition method, that can be used for solving large-scale structured Linear Programs (LPs). The required structure of the LPs is the same as in the original DantzigWolfe approach, that is, a polyhedron over which optimization is “easy” plus a set of “complicating” constraints. Under the hypothesis that an alternat...

A Computational Study of Dantzig-Wolfe Decomposition

A Computational Study of Dantzig-Wolfe Decomposition James Richard Tebboth This thesis evaluates the computational merits of the Dantzig-Wolfe decomposition algorithm. We use modern computer hardware and software, and, in particular, we have developed an efficient parallel implementation of Dantzig-Wolfe decomposition. We were able to solve problems of up to 83,500 rows, 83,700 columns, and 622...
