WebBFS has a time complexity of O(V + E) where V is the number of vertices and E is the number of edges. It must also take into account each nodes neighbours, making it an expensive search algorithm. DFS, on the other hand, has a time complexity of O(V + E) as it does not explore all nodes equally, which makes it a faster solution than BFS. WebJul 7, 2024 · Here are the illustration for DFS vs BFS: We can easily see that in most case, it is faster to use BFS than DFS to find one solution, but DFS takes less memory than BFS.

WebApr 7, 2016 · When using BFS, if your tree has a very large amount of spread compared to it's depth, and you're expecting results to be found at the leaves, then clearly DFS would make much more sense here as it reaches leaves faster than BFS, even though they both reach the last node in the same amount of time (work). WebOct 4, 2024 · BFS will always run faster than DFS. False: If a BFS and DFS prioritize the same nodes (e.g., both always choose to explore the lower numbered node first), BFS will always run at least as fast as DFS when run on two nodes in KN. ...

"WebAnswer is not correct about memory usage. Both can consume worse case O (V) memory. Worse case for BFS is one parent with n child while the worse case for DFS is chain of n nodes with one child per parent. So depending on graph topology, BFS or DFS both have equal chance of winning. – Shital Shah. " - Dfs faster than bfs
