Due to physical limits, hardware development no longer results in higher speed for sequential algorithms, but rather in increased parallelism. Modern commodity PCs include a multi-core CPU and at least one GPU, providing a low cost, easily accessible heterogeneous environment for high performance co...

In many cases there is still a large gap between the performance of current optimization technology and the requirements of real-world applications. As in the past, performance will improve through a combination of more powerful solution methods and a general performance increase of computers. These...

We study how to implement local search efficiently on data parallel accelerators such as Graphics Processing Units. The Distance-constrained Capacitated Vehicle Routing Problem, a computationally very hard discrete optimization problem with high industrial relevance, is the selected vehicle for our ...

For many applications of vehicle routing, there is still a large gap between the requirements and the performance of today’s decision support systems. Although there has been a tremendous increase in the ability to solve ever more complex VRPs (partly due to methodological improvements, partly due t...

We investigate the performance increase potential of GPU implementations of local search. In particular, we report on how we managed to incrementally improve the implementation of a local search algorithm to a given GPU platform for maximum performance. As our target problem we use the well known Ve...

For many applications of optimized transportation management, there is still a large gap between the requirements and the performance of today’s decision support systems. Vehicle routing is no exception. Although there has been a tremendous increase in the ability to solve ever more complex VRPs (pa...
