What is the A* algorithm and how does it work?
The A* algorithm is a pathfinding and graph traversal algorithm used to find the shortest path from a start node to a target node.
Can you explain how it calculates the shortest path?
Sure! A* uses a cost function that combines the actual cost from the start node and a heuristic estimate of the cost to the target.
What are some common heuristics used in A*?
Common heuristics include the Manhattan distance, Euclidean distance, and Chebyshev distance, depending on the grid layout.
Is A* always the best choice for pathfinding?
A* is efficient and often optimal, but it may not be the best choice in all scenarios, especially with complex graphs.
