WebI usually deal with traversal algorithms such as DFS and BFS, and I have to implement them iteratively. However, in case of DFS, one challenge is that the size of stack can be O ( n + m) in worst case. I was wondering if there is an iterative implementation of DFS that requires an O ( n) size stack instead of heavy O ( n + m) stack. WebThis is the answer to that question. For the answer to the question as asked, see Paul Pacheco’s answer. The worst case is [math]O (E^d) [/math] where d is the diameter.

WebThe worst case occurs when the algorithm has to traverse through all the nodes in the graph. Therefore the sum of the vertices(V) and the edges(E) is the worst-case scenario. …

WebExhaustive search like BFS and DFS are infeasible for huge mazes as the algorithm has to consider potentially trillions of paths until it may eventually find the maze solution. That's where heuristic search like A* can help by directing search efforts in (hopefully) the right direction. DFS is succeptible to getting caught in loops. 3. tru red standard notepadsWebIn the worst case, your algorithm might have to explore every possible node in this tree (if it is not able to stop early before reaching the K th level and backtrack from a higher-up node).
