On location-allocation problems for dimensional facilities
(Springer, 2019)
This paper deals with a bilevel approach of the location-allocation problem with dimensional facilities. We present a general model that allows us to consider very general shapes of domains for the dimensional facilities ...

Mathematical programming formulations for the efficient solution of the k-sum approval voting problem
(Elsevier, 2018-10)
In this paper we address the problem of electing a committee among a set of m candidates and on the basis of the preferences of a set of n voters. We consider the approval voting method in which each voter can approve as ...

Finding the nucleolus of any n-person cooperative game by a single linear program
(Elsevier, 2013-10)
In this paper we show a new method for calculating the nucleolus by solving a unique minimization linear program with O(4n) constraints whose coeffi- cients belong to {−1, 0, 1}. We discuss the need of having all these ...

An application of integer programming to the decomposition of numerical semigroups
(Society for Industrial and Applied Mathematics, 2012)
This paper addresses the problem of decomposing a numerical semigroup into mirreducible numerical semigroups. The problem originally stated in algebraic terms is translated, introducing the so-called Kunz-coordinates, to ...

A modeling framework for ordered weighted average combinatorial optimization
(Elsevier, 2014-05)
Multiobjective combinatorial optimization deals with problems considering more than one viewpoint or scenario. The problem of aggregating multiple criteria to obtain a globalizing objective function is of special interest ...

A discretization result for some optimization problems in framework spaces with polyhedral obstacles and the Manhattan metric
(Elsevier, 2018-07)
In this work we consider the shortest path problem and the single facility Weber location problem in any real space of finite dimension where there exist different types of polyhedral obstacles or forbidden regions. These ...

On minimax and Pareto optimal security payoffs in multicriteria games
(Elsevier, 2018)
In this paper, we characterize minimax and Pareto-optimal security payoff vectors for general multicriteria zero-sum matrix games, using properties similar to the ones that have been used in the single criterion case. ...

Partial Gröbner bases for multiobjective integer linear optimization
(Society for Industrial and Applied Mathematics, 2012)
This paper presents a new methodology for solving multiobjective integer linear programs (MOILP) using tools from algebraic geometry. We introduce the concept of partial Gr¨obner basis for a family of multiobjective programs ...

Optimal arrangements of hyperplanes for SVM-based multiclass classification
(Springer, 2019-07)
In this paper, we present a novel approach to construct multiclass classifiers by means of arrangements of hyperplanes. We propose different mixed integer (linear and non linear) programming formulations for the problem ...
