Can you compare a star and BFS?

What are the main differences between the A* algorithm and Breadth-First Search?

A* is a pathfinding algorithm that uses heuristics to find the shortest path efficiently, while BFS explores all nodes at the present depth before moving on to nodes at the next depth level.

Can you explain how the heuristic in A* works?

Sure! The heuristic in A* estimates the cost from the current node to the goal, helping prioritize which paths to explore first.

Which algorithm is generally faster in practice?

A* is usually faster than BFS in practice, especially in large search spaces, because it uses heuristics to guide its search.

Are there scenarios where BFS might be preferred?

Yes, BFS is preferred when the shortest path is required in an unweighted graph, as it guarantees finding the shortest path.
