An algorithm with a complexity linear in the number of vertices is proposed for the computation of the Hyper-Wiener index of chemical trees. This complexity...

La Recherche à Voisinage Variable (RVV) est une métaheuristique récente basée sur l'idée d'un chargement systématique de voisinage, à la fois dans une phase...

This paper considers the problem of locating a facility not among demand points, as is usually the case, but among demand regions which could be market area...

We consider the problem of locating a line or a line segment in three-dimensional space, such that the sum of distances from the facility represented by the...

We consider a given set of offshore platforms and onshore wells, producing known (or estimated) amounts of oil, to be connected to a port. Connections may t...

Given a set of logical sentences and probabilities that these sentences are true, the probabilistic logic problem consists in determining whethe...

Variable Neighborhood Search (VNS) is a recent metaheuristic which exploits systematically the idea of change of neighborhood within the search. After recal...

We review the work of B. Roy in graph theory and its posterity.

Given a set of logical sentences together with nonnegative weights assigned to each of them, the Maximum Weight Satisfiability problem (MAX-WEIGHT SAT) cons...

We modify the algorithm of Pardalos and Rodgers [40] for the minimization of a pseudo-boolean quadratic function by introducing an easy to compute lower bou...

The set of equilibrium points of a bimatrix game is the union of polytopes that are not necessarily disjoint. Knowledge of the vertices of these polytopes ...

Clique partitionning in Euclidean space <b>R</b>ⁿ consists in finding a partition of a given set of <i>N</i> points into <i>M</i> clusters in ord...

The operating schedule problem in open-pit mine can be associated with the problem of maximal closure on a graph. In the literature, the Lagrangian relaxati...

Assigning locomotives and cars to a set of scheduled trains is a complex but important problem for passenger railways. This task is normally carried out in ...

We present a fast tabu search method for the design of access tree networks. We connect a population of users to a set of switches using a variety of SONET ...

Le problème de plus court chemin avec contraintes de ressources consiste à trouver un chemin d'un point origine à un point destination de coût minimum et re...

We propose a network design model for flat networks using hybrid optical/electronic equipments. We describe a set of network components that can be taken in...

Cet article de vulgarisation donne un bref aperçu des travaux réalisés en gestion des opérations dans les grands réseaux de transport. On y fait principalem...

Given a set of flight legs to be flown by a single type of aircraft, the simultaneous aircraft routing and crew scheduling problem consists of determining a...

Let <i>G</i> be a multigraph containing no minor isomorphic to <i>K</i>_3,3 or <i>K</i>₅<i>e</i> (where <i>K</i>₅<i>e</i> de...
