Abstract
A system is disclosed for determining a path in a network that decreases the number of disk accesses needed during the pathfinding computation. The network is divided in to a set of tiles. Certain sub-paths are pre-computed. The pre-computed sub-paths are grouped into webs. When finding a path, the system will perform a pathfinding exploration within the tile for the origin and a pathfinding exploration within the tile for the destination. A number of the webs will be used with the two explorations to determine a path from the origin to the destination.
