WebApr 21, 2024 · Two points I'd like to make: 1) Dijkstra vs A* Dijkstra's algorithm is a dynamic programming algorithm, not an heuristic. A* is an heuristic because it also uses an heuristic function (lets say h(x) ) to "estimate" how close a point x is getting to the end point. This information is exploited in subsequent decisions of which nodes to explore next.
