WebAn algorithm due to Schmidt [64] is based on chain decomposition of graphs to determine biconnectivity (and/or 2-edge connected). All these algorithms take O(m + n) time and O(n) words of space. Roughly these approaches compute DFS and process the DFS tree in specific order maintaining some auxiliary information of the nodes. We start with a ... In graph theory, a biconnected graph is a connected and "nonseparable" graph, meaning that if any one vertex were to be removed, the graph will remain connected. Therefore a biconnected graph has no articulation vertices. The property of being 2-connected is equivalent to biconnectivity, except that the complete graph of two vertices is usually not regarded as 2-connected.
