Part of the Lecture Notes in Computer Science book series (LNCS, volume 6067)


The MPI and OpenMP implementations of the parallel simulated annealing algorithm solving the vehicle routing problem (VRPTW) are presented. The algorithm consists of a number of components which co-operate periodically by exchanging their best solutions found to date. The objective of the work is to explore speedups and scalability of the two implementations. For comparisons the selected VRPTW benchmarking tests are used.
