Sep 18, 2020 · We propose an efficient cache construction method to select the cached shortest paths from the query log.
Fingerprint. Dive into the research topics of 'Improving the Cache-Efficiency of Shortest Path Search'. Together they form a unique fingerprint.
Jul 8, 2015 · You can use Dijustra to search for the shortest path between one node and all other nodes, and cache all the length of the shortest paths using ...

In this paper, we study how to refresh a cache when one edge of the underlying road network (graph) changes.
We utilize statistics from query logs to estimate the benefit of caching a specific shortest path, and we employ a greedy algorithm for placing beneficial paths ...
Furthermore, we design a hybrid index for the shortest paths in the cache, so that the efficiency of shortest path querying is significantly improved.
The caching has been developed for shortest path queries. At present, existing methods for the shortest path caching include the dynamic cache method ...
A∗ search with our landmark-based lower bounds yields a major performance improvement. BLA is the algorithm with the highest efficiency. Its efficiency is ...
