In this paper, we focus on the problem that has been described in the second international nurse rostering competition: a personalized nurse scheduling prob...

In this paper, we describe an algorithm for the personalized nurse scheduling problem. We focus on the deterministic counterpart of the specific problem t...

Nous considérons les problèmes d'optimisation sans dérivées avec variables continues, entières, discrètes et de catégorie dans le contexte d'applications i...

Distance measures play an important role in data analysis, mainly for clustering purpose, but also for data representation (for instance using multidimension...

We study the lattice structure of random number generators of the MIXMAX family, a class of matrix linear congruential generators that produce a vector of...

The search neutrality debate is about whether search engines should or should not be allowed to uprank certain results among the organic content matching a...

This study presents a production scheduling optimization method for a mining complex, which provides a flexible long-term plan for future investments and ope...

Partially observed major minor LQG mean field game theory is applied to an optimal execution problem in finance; following standard financial models, control...

En tomographie par émission de positron (PET), des cristaux longs (>20 mm) doivent être utilisés pour augmenter l'efficacité de détection et la sensibilité d...

On considère un problème dynamique d’optimisation du prix et des dépenses publicitaires où la dynamique de réputation de la marque évolue à la Nerlove-Arrow....

Given an integer solution, the integral simplex using decomposition (ISUD) seeks a descent direction that leads to an improved adjacent integer solution. It ...

Cet article analyse l'effet stratégique d'investir en adaptation dans un jeu dynamique de pollution transfrontalière à horizon fini. Nous intégrons l'adaptat...

We propose a lemma that clarifies the proof of Theorem 4.1 on densities of sums in Rudelson and Vershynin. More precisely, by denoting by \(f_{S+Y}\) the d...

Global optimization problems are very hard to solve, especially when the nonlinear constraints are highly nonconvex, which can result in a large number of di...

We consider a dynamic game model of ride-sourcing, where a large number of private car owners provide rides to randomly appearing customers. Free drivers c...

We study X-ray tomograqphic reconstruction using statistical methods. The problem is expressed in cylindrical coordinates, which yield significant computatio...

Maintenance activities help prevent costly generator breakdowns but because generators under maintenance are typically unavailable, the impact of maintenance...

La Programmation Dynamique Stochastique (PDS) est une puissante méthode applicable aux problèmes mutli-étapes non-convexes et stochastiques. Nous étudions ...

La contrefaçon, qui peut être définie comme le fait de copier illégalement des biens de marque, est un phénomène répandu à travers le monde. Si la production...

We examine the stability of international environmental agreements when they include both adaptation and mitigation policies. We assume that adaptation req...
