The problem of finding a minimum weight k-vertex connected spanning sub-ลฝ . graph in a graph G s V, E is considered. For k G 2, this problem is known to be NP-hard. Combining properties of inclusion-minimal k-vertex connected graphs ลฝ and of k-out-connected graphs i.e., graphs which contain a vertex
The problem of finding a minimum weight k-vertex connected spanning sub-ลฝ . graph in a graph G s V, E is considered. For k G 2, this problem is known to be NP-hard. Based on the paper of Auletta, Dinitz, Nutov, and Parente in this issue, ร 4 we derive a 3-approximation algorithm for k g 4, 5 . This
A linear time 5 3 -approximation algorithm is presented for the NP-hard problem of finding a minimum strongly-connected spanning subgraph. It is based on cycle contraction that was first introduced by Khuller, Raghavachari and Young [SIAM J. Comput. 24 (1995) 859-872]. We improve their result by con
