Generally, the semiclosed-form option pricing formula for complex financial models depends on unobservable factors such as stochastic volatility and jump int...

In this paper, we address a personalized multi-department multi-day shift scheduling problem with a multi-skill heterogeneous workforce where employees can b...

Vehicle routing problems (VRPs) are among the most studied problems in operations research. Nowadays, the leading exact algorithms for solving many classes o...

In this paper, we present an online reinforcement learning algorithm, called Renewal Monte Carlo (RMC), for infinite horizon Markov decision processes with ...

Clustering is an automated and powerful technique for data analysis. It aims to divide a given set of data points into clusters which are homogeneous and/o...

The vertex \(p\)-center problem consists in selecting \(p\) centers among a finite set of candidates and assigning a set of clients to them, with the aim...

Le paradoxe de Parrondo est étendu à des marches aléatoires en environnements aléatoires avec changement de régimes. Le comportement paradoxal de la march...

The survivorship bias in credit risk modeling is the bias that results in parameter estimates when the survival of a company is ignored. We study the statist...

Within state-of-the-art optimization solvers such as IBM--CPLEX the ability to solve both convex and nonconvex Mixed-Integer Quadratic Programming (MIQP) pro...

For over a decade, stochastic optimization has emerged as a framework that is capable of generating a life-of-mine production schedule that increases ne...

Relatively recent techniques for categorical simulations are based on multi-point statistical approaches where a training image is used to derive complex spa...

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...

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...

Dans cet article, nous résolvons le problème de réplication optimale en temps discret lorsque les rendements d'actifs suivent un modèle auto-régressif multiv...

Dans cet article, nous présentons d'abord une analyse des outils statistiques qui peuvent être utilisés dans la gestion des actifs soit pour reproduire des i...

The bid construction problem (BCP) for combinatorial total truckload transportation service procurement auctions consists of determining one or several bids ...

We consider the problems of determining the metric dimension and the minimum cardinality of doubly resolving sets in \(n\)-cubes. Most heuristics develope...

We consider the multivariate linear model for multilevel data where units are nested within a hierarchy of clusters. We propose permutation procedures to te...

In this study, the problem environment consists of two fast fashion retailing firms where one can obtain the other's selling data from an outside agent. The ...

Récemment, deux approches différentes basées sur la fonction copule ont été proposées pour estimer la fonction des quantiles conditionnels d'une variable `...
