We describe LNLQ for solving the least-norm problem \(\min\ \|x\|\) subject to \(Ax=b\). Craig's method is known to be equivalent to applying the conjug...

The parallel space decomposition of the Mesh Adaptive Direct Search algorithm (PSD-MADS proposed in 2008) is an asynchronous parallel method for constrained ...

Nanotherapy represents a promising approach to target tumors with anticancer drugs while minimizing systemic toxicity. Evaluation of nanoparticle (NP) design...

On considère le problème de détermination de politiques optimales de publicité et de prix pour un spectacle. On suppose que les organisateurs désirent que t...

Derivative-free optimization (DFO) is the mathematical study of the optimization algorithms that do not use derivatives. One branch of DFO focuses on model-...

Metros and other rapid transit systems increase the mobility of urban populations while decreasing congestion and pollution. There are now 187 cities with a ...

Clustering is the subject of active research in several fields such as operations research, statistics, pattern recognition, and machine learning. The range ...

This paper focuses on the traveling salesman problem with time windows (TSPTW) that arises in postal services and parcel deliveries and has features differin...

This paper introduces two classes of location problems with interconnected facilities. These problems differ from classical location problems in the sense ...

Les programmes de subvention pour accélérer le remplacement d’une voiture ayant un certain âge ont été très populaires un peu partout dans le monde. Ils ava...

Employee scheduling is an important activity in the service industry as it has a significant impact on costs, sales, and profitability. While a large amount ...

The mesh adaptive direct search (MADS) algorithm is designed for blackbox optimization problems for which the functions defining the objective and the constr...

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...

Dans le cadre du calcul du risque de contrepartie, le risque de corrélation réfère à une situation où la valeur d'une transaction financière est corrélée av...

À la suite de la crise financière de 2007, la réforme de Bâle III recommande, entre autres, la mise en place de frais de capital couvrant la variabilité de ...

We analyze a transboundary pollution differential game where, in addition to the standard temporal dimension, a spatial dimension is introduced to capture th...

We propose an infeasible interior-point algorithm for constrained linear least-squares problems based on the primal-dual regularization of convex program...

We investigate surrogate-assisted strategies for global derivative-free optimization using the mesh adaptive direct search MADS blackbox optimization algorit...

Energy and the environment are closely interconnected. In particular, energy-related carbon dioxide emissions are major contributors to climate change. To an...

The classical p-median problem assumes that service to customers is always provided by the closest facility, while in practice, customers often interact for...
