A computational study of a nonlinear minsum facility location problem
(PERGAMON-ELSEVIER SCIENCE LTD, 2012-01-31)
A discrete location problem with nonlinear objective is addressed. A set of p plants is to be open to serve a given set of clients. Together with the locations, the number p of facilities is also a decision variable. The ...

Solving Multifacility Huff Location Models on Networks Using Variable Neighborhood Search and Multi-Start Local Search Metaheuristics
(Elsevier, 2012-12-01)
We consider multifacility Huff location problems on networks. The mixed integer nonlinear optimization problem is solved using Variable Neighborhood Search and Multi-Start Local Search metaheuristics. Computational experience ...

VNS heuristic for the (r|p)-centroid problem on the plane
(Elsevier, 2012-12-01)
In the (r | p)-centroid problem, two players, called leader and follower, open facilities to service clients. We assume that clients are identified with their location on the Euclidean plane, and facilities can be opened ...

Modelo estadístico para la predicción del índice estandarizado de sequía pluviométrica (IESP) en Andalucía
(Universidad de Salamanca, 2012)
La comunicación aborda el diseño de un modelo estadístico de predicción dinámica de la sequía en Andalucía y su persistencia en un horizonte temporal de 12 meses a partir de los datos históricos (1950-2012) del Índice ...

Gaussian variable neighborhood search for continuous optimization
(PERGAMON-ELSEVIER SCIENCE LTD, 2012-01-01)
Variable Neighborhood Search (VNS) has shown to be a powerful tool for solving both discrete and box-constrained continuous optimization problems. In this note we extend the methodology by allowing also to address unconstrained ...
