Webbecause BFS’s traversal order doesn’t take into account weights. We can use the edge weights (total distance) to figure out the exact order to visit things in so our algorithm is correct vDijkstra’s algorithm = this differently ordered traversal / algorithm to find the shortest path on weighted graph WebThe queue used to determine the order in which vertices will be discovered. If a FIFO queue is used, then the traversal will be according to the usual BFS ordering. Other types of queues can be used, but the traversal order will be different. For example Dijkstra's algorithm can be implemented using a priority queue.
