What is the complexity of the A* algorithm?
The A* algorithm has a time complexity of O(b^d) in the worst case, where b is the branching factor and d is the depth of the solution.
Can you explain what branching factor means?
Sure! The branching factor is the average number of child nodes for each node in a search tree. It affects the algorithm's efficiency.
How does A* compare to Dijkstra's algorithm in terms of complexity?
A* is generally more efficient than Dijkstra's algorithm because it uses heuristics to guide the search, potentially reducing the number of nodes explored.
What are some common heuristics used in A*?
Common heuristics include the Manhattan distance, Euclidean distance, and the Chebyshev distance, depending on the problem space.
