What are the different pathfinding techniques and how do they compare?

There are several pathfinding techniques, including A*, Dijkstra's algorithm, and Breadth-First Search. A* is often preferred for its efficiency and ability to find the shortest path using heuristics.

Can you explain how A* works?

Sure! A* uses a cost function that combines the actual distance from the start node and an estimated distance to the goal. It explores paths that minimize this cost.

What are the advantages of using Dijkstra's algorithm?

Dijkstra's algorithm guarantees the shortest path in graphs with non-negative weights, making it reliable for many applications, though it can be slower than A*.

Are there any scenarios where Breadth-First Search is more effective?

Yes, BFS is effective in unweighted graphs where all edges have the same cost, as it explores all neighbors at the present depth before moving on.
