Depth-first Search, Breadth-first Search, and the Greedy Algorithm

WebAug 30, 2024 · In summary, greedy BFS is not complete, not optimal, has a time complexity of $\mathcal{O}(b^m)$ and a space complexity which can be polynomial. A* is complete, optimal, and it has a time and space complexity of $\mathcal{O}(b^m)$. So, in general, A* uses more memory than greedy BFS.
