The energy of a graph G
, denoted by E(G)
, is defined as the sum of the absolute values of all eigenvalues of G
. In this paper we stu...
Column generation algorithms for solving vehicle routing problems often rely on a relaxed pricing subproblem where routes may be non-elementary and which is ...

The standard blending problem consists of combining components to produce a final product with a given demand, while satisfying specific criteria with resp...
BibTeX reference
We address the problem of accelerating column generation (CG) for set-covering formulations via dual optimal inequalities (DOI). DOI use knowledge of the du...

This paper presents the application of adaptive simultaneous stochastic optimization with a representative branching framework to generate the strategic pl...
BibTeX reference
We built a time-consistent cooperative solution for the class of dynamic games played over event trees in the context where the structure of the tree is gi...
BibTeX reference
We analyze a differential game with spatially distributed controls to study a multiregional transboundary pollution problem. The dynamics of the state variab...
BibTeX reference
The integral column generation algorithm (ICG) was recently introduced to solve set partitioning problems involving a very large number of variables. This pr...

In derivative-free and blackbox optimization, the objective function is often evaluated through the execution of a computer program seen as a blackbox. It ...
BibTeX referenceValue-based production planning in non-ferrous metal industries: Application in the copper industry
Production planners in the non-ferrous metal industry face an inherent combinatorial complexity of the metal production process within a fast changing market...
