Lagrangian relaxations for the nonlinear p-median problem

Author(s)
I. L. Vasilyev, A. V. Ushakov
Abstract

In this paper we study a modification of well-known p-median problem, in which the number of facilities is a non-fixed value. We consider the problem statement and propose a heuristic method to get lower bounds of the optimal values.

Keywords
the p-median problem, Lagrangian relaxation, lower bounds, subgradient algorithm
