Abstract

We present a branch-and-bound algorithm for solving the p -median problem. The bounds are obtained by solving the Lagrangian relaxation of the p -median problem using the subgradient optimization method. The proposed algorithm is simple, requires small core storage and computational time, and can be used for solving large problems. Comparative results are also reported.
