Abstract

As for the tme-efficient A* algorithm significantly reduces the algorithm time, lead to the problem of increase path planning length and path sawtooth. This paper proposed an improved bidirectional time-efficient A* algorithm, which ran the A* algorithm from the start and the end point to find the path and applied the multiple neighbor grid distance computation scheme. At the same time, according to different environment map, this paper compared and analyzed the A* algorithm, time-efficient A* algorithm and bidirectional time-efficient A* algorithm. Finally, it chose the index of algorithm time and path length as two indicators to evaluate the merits and demerits of the algorithm. Experimental results show that compared with traditional A* algorithm, the bidirectional time-efficient A* decreases the time of the algorithm by 76.8% at the maximum, and reduces the maximum time by 55.4% compared with time-efficient A* algorithm. It also solves the problem that the path distance of the time-efficient A* algorithm is augmented and the path is not smooth enough.
