In e-commerce warehouses, online retailers increase their efficiency by using a mixed-shelves (or scattered storage) concept, where unit loads are purposeful...
BibTeX referenceThe conditional \(p\)-dispersion problem
We introduce the conditional \(p\)
-dispersion problem (c-pDP), an incremental variant of the \(p\)
-dispersion problem (pDP). In the c-pDP, one is given a...
Statistical image reconstruction in X-Ray computed tomography yields large-scale regularized linear least-squares problems with nonnegativity bounds, where t...
BibTeX reference
In the present paper, we prove lower and upper bounds for each of the ratios \(GA/\delta\)
, as well as a lower bound on \(GA/\sqrt{\delta}\)
, in terms of...
A small polygon is a polygon of unit diameter.
The question of finding the largest area of small \(n-\)
gons
has been answered for some values of \(n\)
....
Mathematical models of energy-economy-environmental systems (E3) provide a rational framework for exploring the effects of energy and climate policies and su...
BibTeX reference
The introduction of renewable energy sources (RES) changes the shape of an electricity system's supply curve. In a perfectly competitive market, this causes ...
BibTeX reference
We address a stochastic three-level lot sizing and replenishment problem with a distribution structure in a two-stage decision process. We consider one produ...
BibTeX reference
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...
BibTeX reference
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, ...
