A Parallel Algorithm for the Vehicle Routing Problem

Journal Article · · INFORMS Journal on Computing
The vehicle routing problem (VRP) is a dicult and well-studied combinatorial optimization problem. We develop a parallel algorithm for the VRP that combines a heuristic local search improvement procedure with integer programming. We run our parallel algorithm with as many as 129 processors and are able to quickly nd high-quality solutions to standard benchmark problems. We assess the impact of parallelism by analyzing our procedure's performance under a number of dierent scenarios.
