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

We consider a dynamic collective choice problem where a large number of players are cooperatively choosing between multiple destinations while being influenc...

In this paper we consider an interactive communication system with two users, who sequentially observe two correlated sources, and send the quantized observa...

L'indice géométrique-arithmétique \(GA\) d'un graphe \(G\) est la somme des ratios, sur l'ensemble des arêtes de \(G\), de la moyenne géométrique sur l...

Dans le présent article, nous démontrons des bornes inférieure et supérieure sur chacun des rapports \(GA/\delta\), \(GA/\overline{d}\) et \(\Delta\), ...

Dans le présent article, nous comparons l'indice géométrique-arithmétique \(GA\) et le nombre chromatique \(\chi\) d'un graphe connexe d'ordre donné. Ent...

Inspired by successful biological collective decision mechanisms such as honey bees searching for a new colony or the collective navigation of fish schoo...

The vehicle routing problem with time windows (VRPTW) consists of finding least-cost vehicle routes to satisfy the demands of customers that can be visited...

Variable neighborhood search (VNS) is a framework for building heuristics, based upon systematic changes of neighborhoods both in a descent phase, to find a...

In this paper, we investigate team optimal control of a population of heterogeneous LQ (Linear Quadratic) agents. The population consists of finite distinct...

Cet article traite la prise en compte d'incertitudes lors de la résolution de conflits. Plus particulièrement, nous considérons les incertitudes dues aux err...

Nous présentons un modèle déterministe pour le problème de détection et de résolution de conflits entre aéronefs. Les aspects liés à la dynamique des avions,...

We consider a multi-agent system with linear stochastic individual dynamics, and individual linear quadratic ergodic cost functions. The agents partially o...

Decentralized sequential hypothesis testing refers to a generalization of Wald's sequential hypothesis testing setup in which multiple decision makers make ...

Given a complete directed graph \(G\) with weights on the vertices and on the arcs, a \(\theta\)-improper \(k\)-coloring is an assignment of at most `...

The fundamental limits of remote estimation of Markov processes under communication constraints are presented. The remote estimation system consists of a sen...

In this paper we propose a general variable neighborhood search heuristic for solving the uncapacitated single allocation p-hub center problem (USApHCP). F...

The uncapacitated multiple allocation p-hub center problem (UMApHCP) consists of choosing p hub locations from a set of nodes with pairwise traffic deman...

Usually several neighborhood structures may be explored within a single local search algorithm. The simplest way is to define a single neighborhood as a unio...

In this paper we investigate the options of a network operator faced with the requirement of reducing its carbon footprint, expressed in terms of a global en...
