This study examines simultaneously the effect of personal, contextual, and product-related factors on purchasing behaviour of fair-trade products. The resu...
référence BibTeXOn a Reduction of the Interval Coloring Problem to a Series of Bandwidth Coloring Problems
Given a graph <img src="/cgi-bin/mimetex.cgi?G=(V,E)"> with strictly positive integer weights <img src="/cgi-bin/mimetex.cgi?\omega_i"> on the vertices <img ...
référence BibTeXDiscrete-Time Survival Trees
Tree-based methods are frequently used in studies with censored survival time. Their structure and ease of interpretability make them useful to identify p...
référence BibTeXVariable Neighborhood Search Methods
Main methods, algorithms and applications of the Variable Neighborhood Search metaheuristic are surveyed, in view of a chapter of the <i>Encyclopedia of Opti...

To the best of our knowledge, the complexity of minimum sum-of-squares clustering is unknown. Yet, it has often been stated that this problem is NP-hard. We...

In this paper we study the Capacitated Team Orienteering and Profitable Tour Problems (CTOP and CPTP). The interest in these problems comes from recent devel...

We consider the bandwidth coloring problem, a generalization of the well-known graph coloring problem. For the latter problem, a classical theorem, discover...

The probabilistic satisfiability problem is to verify the consistency of a set of probability values or intervals for logical propositions. The (tight) prob...
référence BibTeXUsing Meta-Heuristics to Find Minimal Unsatisfiable Subformulas in Satisfiability Problems
In this paper, we propose efficient algorithms to extract minimal unsatisfiable subsets of clauses or variables in unsatisfiable propositional formulas. Suc...

We consider the problem of determining the size of a maximum clique in a graph, also known as the clique number. Given any method that computes an upper bou...

In this paper, we consider testing the location parameter with multilevel (or hierarchical) data. A general family of weighted test statistics are introduced...
référence BibTeXVariable Space Search for Graph Coloring
Let <i>G = (V,E)</i> be a graph with vertex set <i>V</i> and edge set <i>E</i>. The <i>k</i>-coloring problem is to assign a color (a number chosen in {1,.....

The problem retained for the ROADEF’99 international challenge was an inventory management problem for a car rental company. It consists in managing a given...
référence BibTeXThe Jackknife Revisited: Feature Selection in Linear Programming Approaches to Credit Scoring
We discuss feature selection approaches within the context of linear programming models for discrimination, with special emphasis on a new interpretation an...
référence BibTeXExplicit Martingale Representations for Brownian Functionals and Applications to Option Hedging
Using Clark-Ocone formula, explicit martingale representations for path-dependent Brownian functionals are computed. As direct consequences, explicit martin...
