Selected Topics in Column Generation
Dantzig-Wolfe decomposition and column generation, devised for linear programs, is a success story in large scale integer programming. We outline and relate ...

This paper proposes a two-player, finite-horizon differential game model to analyze joint implementation in environmental projects, one of the flexible mecha...
référence BibTeXRouting and Wavelength Assignment in Single Hop All Optical Networks with Minimum Blocking
WDM networks offer a technology that can transferred several optical signals into a single optical fiber. This allows for more efficient use of the huge capa...

A constant fixed cost of establishing a facility is introduced within the framework of minisum facility location in the continuous space. The solution metho...
référence BibTeX
Linear mixed 0-1 integer programming problems may be reformulated as equivalent continuous bilevel linear programming (<i>BLP</i>) problems. We exploit the...

In this exploratory study, a segmentation analysis of a shopping mall’s customers is conducted according to the activities they performed during their visit,...
référence BibTeXVirtual Distribution Systems: Review and a Proposed Integrated Model with Research Initiatives
In this article, we attempt to give a comprehensive review of how classical supply chain models have evolved with advances in information technology and its ...

The integrated aircraft routing and crew scheduling problem consists in determining a minimum-cost set of aircraft routes and crew pairings such that each fl...
référence BibTeX
Column generation is often used to solve problems involving set partitioning constraints, such as vehicle routing and crew scheduling problems. When these co...

This paper examines the convergence properties of two well-known heuristics: variable neighborhood search (VNS) and random multistart local search (MLS). Bot...
référence BibTeXBounds for Probability of Success of Classical Genetic Algorithm based on Hamming Distance
Genetic algorithm has proven itself to be a fairly good optimization algorithm. Despite its many successful applications, there is a lack of theoretical ...
