Webnecessary partially explored sequenced routes when exploring the graph. To conquer this challenge, we propose a dominance relationship between two partially explored sequenced routes r and r′. If r dominates r′, the optimal (i.e., least-cost) feasible sequenced route extended from r is always better than that of r′. WebOnline trip planning is a popular service that has facilitated a lot of people greatly. However, little attention has been paid to personalized trip planning which is even more useful. In …

Optimal Sequenced Route Query with POI Preferences

Web5 de nov. de 2008 · Trip planning search (TPS) represents an important class of queries in Geographic Information Systems (GIS). In many real-world applications, TPS requests are issued with a number of constraints. Unfortunately, most of these constrained TPS cannot be directly answered by any of the existing algorithms. By formulating each restriction … To 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. Given the search space \mathbb {S} and m RR-Trees of C 1 ,C 2 ,⋅⋅⋅,C m , where the Random … Ver mais Algorithm 1 describes the details of guessing, where the main loop iteratively generates routes and finally returns them. Specifically, each iteration generates a feasible route r according to the specified policy (lines 4-10) and … Ver mais To utilize the guessed optimal points, our observation is that when they are put together with proper points, their performance is high; on the contrary, when unbefitting points constitute a route, they may behave ordinarily … Ver mais literary captain
