Let T be the DFS tree resulting from DFS traversal on a connected directed graph the root of the tree is an articulation point, iff it has at least two children. 2. When BFS is carried out on a directed graph G, the edges of G will be classified as tree edge, back edge, or cross edge and not forward edge as in the case of DFS.
