A* implies that you have a heuristic function pointing towards a known destination. It&#x27;s about knowing <i>where</i> you want to go, but not <i>how to get there</i>.<p>In this case, we don&#x27;t know where in the solution space the best solution will be. It&#x27;s not even that easy to tell if we&#x27;ve found it. So that rules out simple pathfinding algorithms like A*.
