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 ...
