Abstract
The NP-completeness and an O(V 3) approximation algorithm are shown for the three-edge-connectivity augmentation problem: given a complete graph G =(V , E ), a spanning subgraph G 0=(V , E \´), and a cost function c of E into nonnegative integers, find E "⊆E -E \´ of minimum total cost such that the graph (V , E \´ ∪ E ") is simple and three-edge connected. It is proved that the problem is NP-complete, even if G 0 is two-vertex connected, and that the approximate solution obtained in this case has a total cost less than that of a certain spanning tree determined by G 0
