We analyze a transboundary pollution differential game where pollution control is spatially distributed among a number of agents with predetermined spatial r...

Les heuristiques basées sur la théorie des graphes sont largement utilisées dans plusieurs domaines pour résoudre approximativement des problèmes d'optimisat...

Dans cet article, nous nous intéressons à létude des valeurs propres du laplacien des distances d'un graphe connexe d'ordre \(n\) et de nombre chromatique ...

Le Problème de Transportà la Demande (PTAD) consiste à définir un ensemble de tournées pour acheminer des clients de leur point d'origine à leur point de des...

An electronic nose (e-nose), or artificial olfactometer, is a device that analyzes the air to quantify odor concentration using an array of gas sensors. Thi...

We study distributed methods for online prediction and stochastic optimization. Our approach is iterative: in each round nodes first perform local computatio...

Le problème de la détermination du plus grand sous-graphe \(k\)-colorable (\(k\)-MCSP) consiste à colorer autant de sommets que possible avec au plus `...

On considère un jeu dynamique défini sur un arbre d’évènements avec temps terminal aléatoire. On suppose que les joueurs coopèrent pour maximiser leur gain ...

The Mesh Adaptive Direct Search algorithm (MADS) is an iterative method for constrained blackbox optimization problems. One of the optional MADS features i...

Two-level orthogonal designs play an important role in industrial screening experiments, in which the primary goal is to identify the treatment factors with ...

Recent developments in the global rare earth elements (REE) sector have caused a surge in motivation for nations outside of China to secure their own REE sup...

A decomposition method is developed to optimize a mineral value chain composed of a one or multiple mines and a material flow circuit. In the proposed decomp...

As open pit mining of a mineral deposit deepens, the cost of extraction may increase up to a threshold where transitioning to mining through underground meth...

High-order sequential simulation techniques for complex and non-Gaussian spatially distributed variables were developed over the last few years. This paper p...

Mineral value chains consist of material from multiple sources, several processing streams, and transportation systems that combine to generate various salea...

Over the past several years, there has been substantial progress in developing new stochastic mine planning optimization models and computationally efficient...

Network characterization and modelling is an important issue to understand and monitor IP network performance, in particular for real-time multimedia appli...

Considering a graph as a network of resistances, Klein and Randić (1993) proposed the definition of a distance measure. Indeed, if each edge of the graph re...

Clustering addresses the problem of finding homogeneous and well-separated subsets, called clusters, from a set of given data points. In addition to the poi...

Dans cet article, nous analysons un jeu de commerce international où les producteurs peuvent librement exporter, mais sont soumis à une tarification au coût ...
