Finding embedded network rows in linear programs I : extraction heuristics by
Robert E Bixby(
Book
)
3 editions published in 1986 in English and held by 4 WorldCat member libraries worldwide
An embedded network within a linear program is, roughly speaking, a subset of constraints that represent conservation of flow. In this paper, we examine three broad classes of heuristic techniquesrowscanning deletion, column scanning deletion, and rowscanning additionfor the extraction of large embedded networks. We describe a variety of implementations, and compare their performance on varied test problems. The success of our tests depends, in part, on several preprocessing steps that scale the constraint matrix and that set aside certain rows and columns. Efficiency of the subsequent network extraction is dependent on the implementation, in predictable ways. Effectiveness is harder to explain; the more sophisticated and expensive implementations seem to be more reliable, but much simpler implementations sometimes find equally large networks. The largest networks are obtained by applying a final augmentation phase, which is studied in the second part of this paper

Solving Staircase Linear Programs BY THE Simplex Method. 2. Pricing(
Book
)
1 edition published in 1979 in English and held by 2 WorldCat member libraries worldwide
This and a companion paper share one goal: to solve staircasestructured linear programs faster through adaptation of the algorithms of the modern simplex method. Their means are quite different however: whereas the preceding paper concentrated on 'inversion' algorithms that factorize the basis and solve linear systems, the present paper looks are 'pricing' algorithms that select a variable to enter the basis at each iteration. Pricing involves two sets of algorithms: computation algorithm that determine reduced costs of the nonbasic variables, and selection algorithms that choose among variables whose reduced costs are favorable. This paper develops staircase adaptations of both sorts of algorithms, and reports extensive (although preliminary) computational experience. Staircase computation algorithms appear to offer modest but consistent savings; staircase selection algorithms, properly chosen, may offer substantial savings in number of iterations, time per iteration, or sometimes both.
