Time-Dependent Route Planning with Generalized Objective Functions, be an approximation of energy consumption, distance, tolls, or other penalties. The resulting problem is NP-hard, but if the additional cost is proportional to driving distance we can solve it optimally on the German road network within 2.3 s using a multi-label A* search. A generalization of time-

New Lower and Upper Bounds for Representing Sequences,unds, and the few lower bounds, known for such representations, and how they interact with the space used. In this article we prove a strong lower bound for ., which holds for rather permissive assumptions on the space used, and give matching upper bounds that require only a compressed representatio

The Stretch Factor of ,,- and ,,-Delaunay Triangulations, .,. of such triangulations, we construct a path whose length is no more than . times the Euclidean distance between . and ., and this bound is the best possible. This definitively improves the 25-year old bound of . by Chew (SoCG ’86). This is the first time the stretch factor of the ..-Delaunay tr

Weighted Geometric Set Multi-cover via Quasi-uniform Sampling,have linear union complexity; for example when the objects are disks, unit cubes or halfspaces in ℝ.. Another consequence is to show that the real difficulty of many natural capacitated set covering problems lies with solving the associated priority cover problem only, and not with the associated multi-cover problem.
