Exact global optimization of the clusterwise regression problem is challenging and there are currently no published feasible methods for performing this clus...

The multi-activity assignment problem consists of assigning interruptible activities to given work shifts so as to match as much as possible for each activit...

Large datasets upon which classical statistical analysis cannot be performed because of the curse of dimensionality are more and more common in many research...

The purpose of this paper is to present and solve a new, important planning problem faced by many shipping companies dealing with the transport of bulk produ...

In view of applications to diagnostic tests of ARMA models, the asymptotic behavior of multivariate empirical and copula processes based on residuals of ARM...

The vehicle routing problem with time windows VRPTW consists of finding least-cost vehicle routes to service given customers exactly once each while satisfyi...

A positive basis is a minimal set of vectors whose nonnegative linear combinations span the entire space R<i>ⁿ</i>. Interest in positive bases wa...

Climate change is one of the greatest challenges facing our planet in the foreseeable future and despite the urgency of the situation global GHG emissions ...

In this paper, we introduce the notion of dynamic copulas to model serial dependence as well as interdependence between several time series. The proposed m...

The traffic evolution is notoriously marked by an increasing dynamism that promotes the design of a dynamic optical layer. Despite the contention issue, Opti...

The focus of this paper is on the design of the so-called Optical Wide Area Networks (OWANs), i.e., optical networks that cover broad areas. Our objective ...

This work introduces a new shared segment protection scheme that ensures both node and link protection in an efficient manner in terms of cost and band...

We consider a multi-layer network design model arising from a real-life telecommunication application where traffic routing decisions imply the installati...

Optical transmission allows massive data transfers thanks to its tremendous transport capacity. Sustained efforts have been made to address the physical co...

Availability requirements in survivable transport networks depend on the type of costumers using the network and the supported services. Nowadays, a variety ...

In today optical WDM networks, capacity expansion is performed by the addition of transport blades (e.g., transceivers) at end nodes of optical fibers. It al...

We study the problem of constructing shifted rank-1 lattice rules for the approximation of high-dimensional integrals with a low weighted star discrepancy, f...

In this paper we establish the definition of the <i>set of &epsilon;-proper equilibria</i> of a bimatrix game. We define a 0-1 mixed quadratic program to ge...

We give an explicit description of the basic solutions of max-linear systems <img src="/cgi-bin/mimetex.cgi?A\otimes x\leq B\otimes x"> with two inequalities.

Dans cet article, on raconte l'histoire de l'équipe GENCOL et du logiciel d'optimisation du même nom. C'est avant tout le récit d'une collaboration qui se po...
