PATH ORACLES FOR SPATIAL NETWORKS |
摘要 |
One embodiment of the invention is directed to a method including constructing a path-distance oracle that provides both an intermediate vertex of a shortest path between two vertices in a spatial network and an approximate distance between the two vertices. The constructing comprises decomposing the spatial network into a set of path-coherent pairs (PCPs) that satisfy at least one predefined property.
