Witryna5 mar 2024 · A* Algorithm in Python or in general is basically an artificial intelligence problem used for the pathfinding (from point A to point B) and the Graph traversals. This algorithm is flexible and can be used in a wide range of contexts. The A* search algorithm uses the heuristic path cost, the starting point’s cost, and the ending point.
