摘要
This paper presents a procedure to solve the convex ordered median problem where the distances are measured with l(p)-norms. In order to do that, we consider an approximated problem and develop an algorithm based on a gradient descent method that generates a sequence with decreasing objective value. We prove its convergence to the optimal solution of the approximated problem. The paper ends with some computational results of the proposed methodology. (C) 2008 Elsevier Ltd. All rights reserved.
