WebFeb 20, 2024 · A* is the most popular choice for pathfinding, because it’s fairly flexible and can be used in a wide range of contexts. A* is like Dijkstra’s Algorithm in that it can be used to find a shortest path. A* is like Greedy Best-First-Search in that it can use a heuristic to guide itself. In the simple case, it is as fast as Greedy Best-First ...
