WebApr 6, 2024 · To solve the above problems, Zhao Hong et al. proposed a modified Dijkstra algorithm by using a bi-directional search technique, which improved the divergent search by searching clockwise or counterclockwise direction, significantly reducing the computing time of the node cost function, but the pathfinding method is still a region-wide … WebMar 27, 2016 · 2. You do not need to put all edges that are adjacent in the priority queue. "Lie" to Dijkstra's algorithm and give it only the shortest vertex, v, incident to the vertex, say w, pulled off the stack. Then, when v is pulled of the queue you say "oops" I made a mistake and should have given you this vertex too, which is the next closest to vertex w.
