How does A* compare to Dijkstra's algorithm?

Can you explain how A* algorithm differs from Dijkstra's algorithm?

Sure! A* is an informed search algorithm that uses heuristics to find the shortest path, while Dijkstra's algorithm is uninformed and explores all possible paths.

What kind of heuristics does A* use?

A* uses heuristics like the Manhattan distance or Euclidean distance, which estimate the cost from the current node to the goal.

When would you choose A* over Dijkstra's?

You'd choose A* when you have a good heuristic that can guide the search efficiently, especially in large graphs.

Are there any scenarios where Dijkstra's is better?

Yes, Dijkstra's is better when you need the shortest path in graphs without a clear heuristic or when all edge weights are equal.

Can both algorithms be used for real-time navigation?

Absolutely! Both algorithms can be applied in real-time navigation systems, but A* is often preferred for its efficiency.
