Edge-connectivity augmentation problems

By Toshimasa Watanabe and Akira Nakamura


AbstractWe give a characterization on the minimum number of edges to be added so as to k-edge-connect a graph. We also show that such a minimum edge set can be determined in O(kL|V|4 (k|V| + |E|)) time for any graph G = (V E) and any fixed k≧2, where L = min {k, | V |
