WebOtherwise, it is called a weakly connected graph if every ordered pair of vertices in the graph is weakly connected. Otherwise it is called a disconnected graph. A k-vertex-connected graph or k-edge-connected graph is a graph in which no set of k − 1 vertices (respectively, edges) exists that, when removed, disconnects the graph. A k-vertex ... WebDec 21, 2024 · By standard terminology, there are definitely 6 strongly connected components (not 4, not 1). The graph is weakly connected. There seems to be some gap where you write "Thus, this graph only contains 1 connected component"; I don't understand how that follows.
