Fully Dynamic Biconnectivity in Graphs to Appear in Algorithmica

  title={Fully Dynamic Biconnectivity in Graphs to Appear in Algorithmica},
  author={Monika U. Rauch},
We present an algorithm for maintaining the biconnected components of a graph during a sequence of edge insertions and deletions. It requires linear storage and preprocessing time. The amortized running time for insertions and for deletions is O(m 2=3), where m is the number of edges in the graph. Any query of the form \Are the vertices u and v biconnected?" can be answered in time O(1). This is the rst sublinear algorithm for this problem. We can also output all articulation points separating… CONTINUE READING
