If all you care about is the forward traversal order, i.e. the order in which the algorithm discovers the new vertices of the graph, then yes: you can take the classic BFS algorithm, replace the FIFO queue with LIFO stack, and you will get pseudo-DFS algorithm. However, I call it ps...
Here is a BFS recursive traversal Python implementation, working for a graph with no cycle. def bfs_recursive(level): ''' @params level: List<Node> containing the node for a specific level. ''' next_level = [] for node in level: print(node.value) for child_node in node.adjency_lis...
Time Complexity The time complexity of the BFS algorithm is represented in the form of O(V + E), where V is the number of nodes and E is the number of edges. Space Complexity The space complexity of the BFS algorithm is O(V). ...

The frontier structure is similar to that applied for implementing the parallel BFS presented in Section 2.1. The main difference from BFS is the number of times a vertex can be inserted in the queue. In BFS, a vertex can be inserted in such a queue only once, while, in the Bellman-For...

Edit: Solution, slightly better as my naive approach could be for every node visited propagate its value recursively back to the root while keeping minimum rank of visited nodes (during back to root traversal). Then adding value only to nodes that have lower than minimal rank. alg...
