Local search with annealing-like restarts to solve the vehicle routing problem with time windows
In this paper, we propose a metaheuristic based on snneedinglikerestarts to diversifyand intensifylocalsearches for solving the vehicle muting problem with time windows (VR_PTW). ...

A constraint hierarchies approach to geometric constraints on sketches
We propose an approach that uses preferences on the constraints in order to deal with over-constrained geometric constraint problems. This approach employs constraint hierarchies,...
