Personnel scheduling consists of determining least-cost work schedules to cover the demand of multiple jobs expressed in number of employees per job and peri...
BibTeX referenceDynamic marketing policies with online-review-sensitive consumers: A mean-field games approach
We consider a large group of consumers who can choose between two products at each purchasing occasion. Their choice is influenced by the marketing strateg...
BibTeX reference
We present a progressive approximation algorithm for the exact solution of several classes of interdiction games in which two non-cooperative players (namely...
BibTeX referenceHyperNOMAD: Hyperparameter optimization of deep neural networks using mesh adaptive direct search
The performance of deep neural networks is highly sensitive to the choice of the hyperparameters that define the structure of the network and the learning pr...
BibTeX referenceVariable fixing for two-arc sequences in branch-price-and-cut algorithms on path-based models
Variable fixing by reduced costs is a popular technique for accelerating the solution process of mixed-integer linear programs. For vehicle routing problems ...

User-centered logistics aiming at customer satisfaction are gaining importance due to growing e-commerce and home deliveries. Customer satisfaction can be ...
BibTeX reference
In this paper, we introduce a class of deterministic finite-horizon two-player non-zero-sum differential games where one player uses continuous control wh...

Significant progress has been made in the field of computer vision, due to the development of supervised machine learning algorithms, which efficiently extra...
BibTeX referenceOptimal dynamic management of a charity
Since nonprofit organizations play an important role in providing goods and services in all countries, this paper aims at determining optimal policies for ...
BibTeX reference
We analyze an endogenous growth model with non-constant discounting and a negative externality of growth on utility. With a decreasing rate of impatience, ...

This paper studies the Dynamic Facility Location Problem with Modular Capacities (DFLPM). We propose a linear relaxation based heuristic (LRH) and an evoluti...
BibTeX reference
We build upon Estrin et al. (2019) to develop a general constrained nonlinear optimization algorithm based on a smooth penalty function proposed by Fletch...
BibTeX reference
In large commercial airlines, the monthly schedule (roster) of the crew members is usually determined by solving two problems sequentially, namely, the crew ...
BibTeX reference
We present a case study of using machine learning classification algorithms to initialize a large scale commercial operations research solver (GENCOL) in the...
BibTeX reference
The minimum residual method (MINRES) of Paige and Saunders (1975), which is often the method of choice for symmetric linear systems, is a generalization of t...

Given \(n\)
points, a symmetric dissimilarity matrix \(D\)
of dimensions \(n\times n\)
and an integer \(p\geq 2\)
, the \(p\)
-dispersion problem (pD...
We study the time evolution of a vertically and horizontally differentiated oligopolistic industry, where firms compete in quantity and are divided into gr...
