Structural and Solution Analysis for the Ordered Weber Problem under Spatial Uncertainty
Víctor Blanco, Miguel Martínez-Antón
We propose a general analytical framework for single-facility continuous location problems under spatial demand uncertainty. In contrast to classical formulations based on discrete…
On the Strength of Linear Relaxations in Ordered Optimization
Víctor Blanco, Diego Laborda, Miguel Martínez-Antón
We study the conditions under which the convex relaxation of a mixed-integer linear programming formulation for ordered optimization problems, where sorting is part of the decision…
A Unified Optimization Framework for Multiclass Classification with Structured Hyperplane Arrangements
Víctor Blanco, Harshit Kothari, James Luedtke
In this paper, we propose a new mathematical optimization model for multiclass classification based on arrangements of hyperplanes. Our approach preserves the core support vector m…
A Mathematical Optimization Approach to Multisphere Support Vector Data Description
Víctor Blanco, Inmaculada Espejo, Raúl Páez +1
We present a novel mathematical optimization framework for outlier detection in multimodal datasets, extending Support Vector Data Description approaches. We provide a primal formu…
Coordinating Drop-Off Locations and Pickup Routes: A Budget-Constrained Routing Perspective
Maria Albareda-Sambola, Víctor Blanco, Yolanda Hinojosa
We introduce in this paper a new variant of a location routing problem, to decide, the number and location of drop-off points to install based on the demands of a set of pick-up po…
A Novel Co-Evolutionary Algorithm for Solving a Bilevel Pricing and Hubs Location Problem under a Tree Topology
Víctor Blanco, José-Fernando Camacho-Vallejo, Carlos Corpus
This paper introduces the Bilevel Tree-of-Hubs Location Problem with Prices (BTHLPwP). The BTHLPwP is a multiple-allocation hub location problem in which, in addition to determinin…
