| Abstract: | This paper presents a new heuristic algorithm for the vehicle routing problem (VRP) which makes use of Lagrangean relaxation to transform the VRP into a modified m-traveling salesman problem. Application of the proposed algorithm to test problems from the literature has produced new best-known solutions. |
