A Mixed Breadth-Depth First Search Strategy for Sequenced Group …
WebAlthough previous studies have investigated trip planning queries, they lack flexibility for finding routes because all of them output routes that strictly match user requirements. We study trip planning queries that output multiple routes in a flexible manner. We propose a new type of query called skyline sequenced route (SkySR) query, which… Websequenced route queries, enabling it to deal with the time-dependency. Our experiments using real and synthetic data sets have shown our proposed solution to be up to two orders of magnitude faster than the temporally extended previous solution. 1. INTRODUCTION The optimal sequenced route (OSR) query was originally introduced in [1]. dark nature wallpaper for pc

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 WebThe optimal sequenced route (OSR) query, as a popular problem in route planning for smart cities, searches for a minimum-distance route passing through several POIs in a specific order from a starting position. In reality, POIs are usually rated … Web1 de abr. de 2024 · Abstract.
