What is the A* algorithm and how does it work?
The A* algorithm is a popular pathfinding and graph traversal algorithm. It finds the shortest path from a start node to a target node using a heuristic to estimate the cost.
Can you explain how the heuristic works in A*?
Sure! The heuristic in A* helps to estimate the cost from the current node to the target node. It guides the algorithm to explore the most promising paths first.
What are some common applications of the A* algorithm?
A* is widely used in various applications, including video games for character movement, robotics for navigation, and geographic information systems for route planning.
Are there any limitations to the A* algorithm?
Yes, A* can be memory-intensive, especially with large graphs, and its performance heavily depends on the heuristic used.
