C*: A Bivariate Best First Search Framework, and C*-P and C*-Dijkstra, to Process Category Sequence Traversal Query in a Graph for Trip Planning
VTIP:09-125
A Category Sequence Traversal Query (CSTQ) is a new type of category based query that determines the minimum-cost path with a predefined origin-destination pair, traversing at least a single selection from each of a set of categories in a specified order. To process CSTQ in a graph corresponds to ...
O*: A Bivariate Best First Search Framework, and O*-SCDMST to Process Optimal Sequence Traversal Query in a Graph for Trip Planning
VTIP:09-126
Optimal Sequence Traversal Query (OSTQ) asks for a minimum-cost path between a given origin and a given destination, traversing a set of points of interest without a predefined order. The traveling salesman problem is a special case of OSTQ. Due to the extensive computing time required to process ...
