WebMay 23, 2024 · The algorithm itself does not have a good sense of direction as to which way will get you to place B faster. The optimal decisions are not made greedily, but are made by exhausting all possible routes that can make a distance shorter. Therefore, it's a dynamic programming algorithm, the only variation being that the stages are not known … WebMany algorithms solve the shortest path problem. Dijkstra’s algorithm is one form of the greedy algorithm. This algorithm includes a graph search algorithm used to solve the shortest path problem with a single source on a graph that does not have a negative side cost and produces the shortest path tree. This algorithm is often used in routing ...
