Dividing a Graph into Triconnected Components
Hopcroft, John E.; Tarjan, Robert Endre
An algorithm for dividing a graph into triconnected components is presented. When implemented on a random access computer, the algorithm requires $O(V+E)$ time and space to analyze a graph with $V$ vertices and $E$ edges. The algorithms is both theoretically optimal to within a constant factor and efficient in practice. Keywords: articulation point, connectivity, depth-first search, graph, separability, separation, triconnectivity.
