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.

Our algorithm first generates a skeleton graph based on any spanning tree of the input graph. Then we use the connectivity information of the skeleton to compute the biconnectivity of the original input.

WebWe also consider the case where the graph has edge weights. We show that an approximation factor of 2 is possible in polynomial time for finding a κ-edge connected spanning subgraph. This improves an approximation factor of 3 for κ = 2 due to [FJ81], and extends it for any κ (with an increased running time though). Original language.
