How does the Astar algorithm work?
Sure, here's a description that simulates the tone of a questioner, asking about the A* (Astar) algorithm: "Could you explain how the A* algorithm functions in simple terms? I've heard it's a popular pathfinding algorithm in computer science and I'm curious about its inner workings. Does it rely on a specific data structure? How does it determine the most efficient path between two points? I'm especially interested in how it balances the cost of reaching a node with the heuristic estimate of the cost to the goal. Can you provide an example or analogy to help me understand it better?
