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

Extreme Learning Machine (ELM) has recently increased popularity and has been successfully applied to a wide range of applications. Variants using regulariza...

The technological developments observed in the last two decades contributed to the digitalization of products and the introduction of devices to consume th...

Planifier les activités d'une mine souterraine est une tâche très complexe. Cet article présente un modèle d'optimisation pour la planification de la ...

In this paper, we introduce a general framework for vector space decompositions that decompose the set partitioning problem into a reduced problem, defined...

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

On considère un jeu dynamique, linéaire dans l'état qui se déroule sur un arbre d'événements. On détermine analytiquement le prix de l'anarchie, ainsi que d...

Dans cet article, nous montrons que les gains coopératifs dans un jeu dynamique défini sur un arbre d'événements peuvent avoir un support stratégique, c'est-...

We use a newly developed model of the entire Canadian energy system (TIMES-Canada) to assess the climate change mitigation potential of different agri-food c...

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...

The subdifferential of a function is a generalization for nonsmooth functions of the concept of gradient. It is frequently used in variational analysis, part...

Inventory routing problems aim at minimizing the cost of the total distance traveled over a time horizon discretized in periods, while guaranteeing that th...

This paper introduces the pickup and delivery problem with time windows and handling operations. In this problem, the loading compartment of a vehicle is mod...

Nous étudions l'impact de la séquence des décisions sur les politiques d'adaptation et de réduction des émissions dans le contexte des problèmes environnemen...

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

For a Neoclassical growth model, exponential discounting is observationally equivalent to quasi-hyperbolic discounting, if the instantaneous discount rate ...

Thermoforming process is a technique widely used in the plastic industry. This process involves three stages: i) sheet heating, ii) forming, and iii) cooling...

Given a flight schedule and a set of aircraft of different types, the airline fleet assignment problem (FAP) consists of assigning an aircraft type to each f...

We model and solve the problem of sequencing a set of jobs with specified processing times and tool requirements on a set of identical parallel machines. D...
