What is the A* algorithm in machine learning?
The A* algorithm is a popular pathfinding and graph traversal algorithm used in AI. It finds the shortest path from a start node to a goal node.
How does A* differ from other pathfinding algorithms?
A* uses heuristics to improve efficiency, combining the cost to reach a node and an estimated cost to the goal, unlike Dijkstra's algorithm which only considers the cost to reach a node.
Can you give me an example of how A* is used in real-world applications?
Sure! A* is commonly used in navigation systems, like GPS, to find the quickest route from one location to another.
What are some common heuristics used with A*?
Common heuristics include the Manhattan distance and Euclidean distance, which estimate the cost to reach the goal based on the current node's position.
