Better Landmarks Within Reach
We study the real algorithm for the point-to-point shortest path problem. It combines A∗ search search, landmark-based lower bounds, and reach-based pruning. We suggest several ...

Clustering Objects on a Spatial Network
Clustering is one of the most important analysis tasks in spatial databases. We study the problem of clustering objects, which lie on edges of a large weighted spatial network. Th...
