What are the differences between pathfinding algorithms?

Pathfinding algorithms are methods used to find the shortest path between points. Common ones include A*, Dijkstra's, and BFS.

Can you explain how A* works?

A* uses a heuristic to estimate the cost from the current node to the goal, combining it with the cost to reach the current node.

How does Dijkstra's algorithm differ from A*?

Dijkstra's algorithm explores all possible paths equally, while A* prioritizes paths that seem more promising based on heuristics.

Which algorithm is the most efficient for large maps?

A* is often more efficient for large maps due to its heuristic approach, but the best choice can depend on the specific scenario.

Are there any scenarios where BFS is preferred?

Yes, BFS is preferred in unweighted graphs where the shortest path in terms of the number of edges is needed.
