An overview is given, with new results, of mathematical models and algorithms for probabilistic logic, probabilistic entailment and various extensions. Anal...

Cylindrical aromatic compounds - fullerenes and hydrocarbons - are about to become highly interesting objects of chemical research. A tubulene (tubular ben...

In a first attempt to explain the good behavior of local improvement heuristics (such as Tabu Search and Simulated Annealing) for the <i>k</i>-coloring prob...

We derive from Boolean methods a transformation which, when it can be applied, builds from a graph <i>G =</i> (<i>V,E</i>) a new graph <i>G'=</i> (<i>V',E'<...

For a weighted graph <i>G =</i> (<i>V,E</i>), the maximum weighted <i>k</i>-coloring problem is to color a set of vertices of maximum weight using <i>k</i> ...

We describe two new classes of graphs for which the stability number can be computed in polynomial time. The first approach is based on an iterative procedu...

The purpose of this paper is to describe a new tabu search heuristic for the vehicle routing problem with capacity and route length restrictions. The algori...

This paper describes a domain criterion for a multicriteria problem, given a single decision maker. It then outlines possibilities for aggregating individua...

We address in this paper the problem of finding an optimal strategy for dealing with bottleneck machines and bottleneck parts in the cell formation process ...

We describe a new class of graphs for which the stability number can be obtained in polynomial time. The algorithm is based on an iterative procedure which...

In this paper the authors describe a heuristic principle for the solution of an important class of problems. Using real-world examples, it is then shown how...

This paper considers the archeological seriation problem defined over incidence matrices. Two procedures adapted from interchange algorithms for the travell...

Dans cet article nous procédons à une segmentation des marchés internationaux. Afin d'éliminer la redondance dans les 27 indicateurs socio-économiques consi...
