What are the differences between A* and Dijkstra's algorithm?
A* is more efficient than Dijkstra's because it uses heuristics to guide its search, while Dijkstra's explores all paths equally.
Can you explain how the heuristic function works in A*?
The heuristic function estimates the cost from the current node to the goal, helping A* prioritize paths that seem more promising.
How does A* compare to Greedy Best-First Search?
A* combines the cost to reach a node and the estimated cost to the goal, while Greedy Best-First Search only considers the estimated cost.
What are some common heuristics used in A*?
Common heuristics include Manhattan distance for grid-based maps and Euclidean distance for continuous spaces.
