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

An edge-coloring of a graph \(G=(V,E)\) is a function \(c\) that assigns an integer \(c(e)\) (called color) in \(\{0,1,2,\dotsc\}\) to every edge `(...

In the literature, graphs are often studied in terms of invariants, for instance the number of vertices or edges, the stability number, the chromatic number ...

When dealing with node or link failures in Software Defined Networking (SDN), the network capability to establish an alternative path depends on controller r...

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

In recent years, a growing interest has been observed in research on RNA (ribonucleic acid), primarily due to the discovery of the role of RNA molecules in ...

La disparition récente d'un écart de cinq ans dans les échéances du panier d'obligations du Trésor faisant l'objet du contrat à terme du Chicago Board of Tra...

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

To solve integer linear programs, primal algorithms follow an augmenting sequence of integer solutions leading to an optimal solution. In this work, we focu...

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

Écrire un texte de qualité est un processus complexe. Plusieurs domaines d'études se penchent sur les possibilités d'analyse des pratiques d'écriture des bon...

We introduce an iterative algorithm for the solution of the diameter minimization clustering problem (DMCP). Our algorithm is based upon two observations: 1)...

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

Traditionally, claim counts and amounts are assumed to be independent in non-life insurance. This paper explores how this oft unwarranted assumption can be r...

In order to determine the risk capital for their aggregate portfolio, property and casualty insurance companies must fit a multivariate model to the loss tri...

Two bivariate extensions of the Skellam distribution were proposed by Genest and Mesfioui (2014), who also derived moment estimators for their dependence par...
