On the basis of a variable-neighbourhood search with the AutoGraphiX software, it is conjectured that for even numbers of atoms the fully conjugated acycli...

A fuzzy clustering problem consists in assigning a set of patterns to a given number of clusters with respect to some criteria such that each of them may be...

A generalization of the Roy-Gallai theorem is presented: it is based on the existence in any oriented graph of a stable set S such that for any node <i>w</i...

Maximum Clique is one of the most studied NP-hard optimization problem on graphs because of its simplicity and its numerous applications. A basic Variable N...

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...

Preapheresis quantification of circulating CD34+ cells (CD34) may be used to predict peripheral blood progenitor cell (PBPC) yield in subsequent leukapheres...

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...

Ce papier présente une nouvelle procédure de classification, appelée PROCFTN, basée sur le domaine de l'aide multicritère à la décision. Le principe général...

In a research synthesis on the prognosis of depression, the outcome of interest has a multinomial distribution with the following typical categories: well, ...

The standard way to solve the static economic dispatch problem with transmission losses is the penalty factor method. The problem is solved iteratively by a...

Systematic change of neighborhood within a possibly randomized local search algorithm yields a simple and effective metaheuristic for combinatorial and glo...

The aim of this paper is to provide a concise portrayal of medical applications of a new fuzzy classification method called PROAFTN, which uses a multicrite...

Weber's problem is to locate a facility in the Euclidean plane in order to minimize total transportation costs from that facility to a given set of users wi...

A model for the optimal location of new facilities in a competitive market is introduced under the hypothesis that customers' behavior can be modeled by ran...

Quatre regards sur la découverte, ceux du psychologue, de l'historien, du sociologue et du cognicien sont évoqués en quelques remarques illustrées d'exemples.

Mirkin's additive clustering (or qualitative factor analysis) algorithm explains similarities between entities by sequentially finding a cluster of entities...

It is shown that a geometrically planar fusene is uniquely determined by its boundary edge code. Surprisingly, the same conclusion is not true in general b...
