WebMay 9, 2024 · A recursive implementation: def dfs (G, u, visited= []): """Recursion version for depth-first search (DFS). Args: G: a graph u: start visited: a list containing all visited nodes in G Return: visited """ visited.append (u) for v in G [u]: if v not in visited: dfs (G, v, visited) return visited. An iterative implementation using a stack: WebStep 1, DFS, takes O(n + m) time. Step 2, inserting each vertex onto the front of a linked list, takes constant time per vertex, or O(n) time altogether. Step 3 is really just saying that the result of step 2 is the answer. So the entire algorithm takes O(n + m) time. I'll go through an example for the goalie-gear dag in class.

This may not generate all edges in G (see edge_dfs ). Specify starting node for depth-first search and yield edges in the component reachable from source.
