A parallel simulated annealing solution for VRPTW based on GPU acceleration

In order to improve the performance of simulated annealing (SA) algorithm while solving the large scale vehicle routing problem with time window(VRPTW), we propose a parallel SA(PSA) algorithm based on GPU-acceleration, which maps parallel SA algorithm to thread block executing on consumer-level graphics cards. The analytical results demonstrate that the method we proposed increases the population size, speeds up its execution and provides ordinary users with a feasible PSA solution. © Springer-Verlag Berlin Heidelberg 2010.
