Hierarchical Hub Labelings for Shortest Paths

Ittai Abraham, Daniel Delling, Andrew V. Goldberg, and Renato F. Werneck


We study hierarchical hub labelings for computing shortest paths. Our new theoretical insights into the structure of hierarchical labels lead to faster preprocessing algorithms, making the labeling approach practical for a wider class of graphs. We also fifind smaller labels for road networks, improving the query speed.
