Article Google Scholar Chen … ctrlkeyshortcutsdisabledTo perform our smart guessing, we first design an Ranged-R-Tree (denoted by RR-Tree) to help efficiently retrieving the POIs, then with the help of the RR-Tree, we propose three ways to effectively guess the feasible routes. An RR-tree not only records the summarized spatial information (i.e., rectangles) but … Ver mais Hence □ The guessing is highly effective to discover the optimal points (p is an optimal point when (p∈r opt )). We have a point collision between two routes r 1 and r 2, if r 1∩r 2≠∅. When … Ver mais Let K guess be the number of routes guessed.
