What are common pathfinding algorithms?

What are some common pathfinding algorithms used in AI?

Common pathfinding algorithms include A*, Dijkstra's algorithm, and Breadth-First Search (BFS). Would you like details on any specific one?

Can you explain how the A* algorithm works?

Sure! The A* algorithm finds the shortest path by combining the cost to reach a node and an estimated cost to the goal. It uses a priority queue to explore nodes.

What are the advantages of using A* over Dijkstra's algorithm?

A* is generally faster than Dijkstra's because it uses heuristics to prioritize paths that are more likely to lead to the goal, reducing the number of nodes it explores.

Are there any scenarios where Dijkstra's algorithm is preferred?

Yes, Dijkstra's algorithm is preferred in scenarios where all edge weights are non-negative and you need the shortest path from a single source to all other nodes.
