In this paper we address a parallel version of subgradient algorithm to maximize Lagrangean dual function for the p-median problem. The parallelization is performed according to the sceme master-slave and using the Message Passing Interface. Computational results for very large-scale instances are given, showing the efficacy of the designed algorithm.

Abstract
In this paper we address a parallel version of subgradient algorithm to maximize Lagrangean dual function for the p-median problem. The parallelization is performed according to the sceme master-slave and using the Message Passing Interface. Computational results for very large-scale instances are given, showing the efficacy of the designed algorithm.File in questo prodotto:
