The eccentricity of a vertex $v$ in a graph $G$ is the maximum distance between $v$ and any other vertex of $G$. The diameter of a graph `(...

A graceful difference labeling (gdl for short) of a directed graph $G$ with vertex set $V$ is a bijection `(f:V\rightarrow{1,\ldots,\vert V\vert}...

Given a directed graph $G=(V,A)$, capacity and cost functions on $A$, a root $r$, a subset $T \subset V$ of terminals, and an integer $k$...

Dans cet article, nous considérons un modèle de pêcherie à deux espèces qui interagissent biologiquement de façon compétitive, symbiotique ou selon une rela...

L'étude des réseaux de télécommunications sans-fil pour cellulaire est importante, car ceux-ci consomment beaucoup d'énergie et ont un impact non négligeable...

This paper addresses combinatorial optimization problems under uncertain and correlated data where the mean-covariance information of the random data is assu...

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

We consider a two-stage stochastic discrete program in which some of the second stage constraints involve expectations that cannot be computed easily and a...

We present a new strategic multi-period optimization problem for the siting of electric vehicle (EV) charging stations. One main novelty in this problem is t...

Smart homes have the potential to achieve optimal energy consumption with appropriate scheduling. It is expected that 35% of households in North America an...

Nous étudions un problème intégré de planification de production et de transport sur trois niveaux avec une structure de distribution (3LSPD), problème qui e...

In the field of Automatic Programming (AP), the solution of a problem is a program, which is usually presented by a tree with a specific structure. This tree...

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

This paper proves the concept that it is feasible to accurately recognize specific human mobility shared patterns, based solely on the connection logs betw...

In this paper we propose C-VNS (Continuous variable neighborhood search) method for finding all solutions to a nonlinear system of equations (NSE). We tran...

We consider an integrated planning problem that combines production, inventory and inbound transportation decisions in a context where several suppliers each...

L'article suivant décrit un modèle mathématique visant à optimiser la planification court- et moyen-terme des mines souterraines. La complexité du problème a...

The Time Window Assignment Vehicle Routing Problem (TWAVRP) is the problem of assigning time windows for delivery before demand volume becomes known. This i...

Les problèmes de gestion de personnel visent à déterminer les horaires de travail les moins coûteux pour couvrir la demande d'une ou plusieurs tâches à chaqu...

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