A general heuristic for vehicle routing problems
We present a unified heuristic, which is able to solve five different variants of the vehicle routing problem: the vehicle routing problem with time windows (VRPTW), the capacit...

Graph transformation approaches for diverse routing in shared risk resource group (SRRG) failures
Failure resilience is a desired feature of the Internet. Most traditional restoration architectures assume single-failure assumption, which is not adequate in present day WDM opti...

Algebraic foundations for effect-dependent optimisations
We present a general theory of Gifford-style type and effect annotations, where effect annotations are sets of effects. Generality is achieved by recourse to the theory of algebra...

Matrix Structures and Parallel Algorithms for Image Superresolution Reconstruction
Computational resolution enhancement (superresolution) is generally regarded as a memory intensive process due to the large matrix-vector calculations involved. In this paper, a de...

An IDF-based trace transformation method for communication refinement
In the Artemis project [13], design space exploration of embedded systems is provided by modeling application behavior and architectural performance constraints separately. Mappin...
