Minmax strongly connected subgraphs with node penalties

Received10 Oct 2002
Revised25 Jul 2003


We propose an O(min{m+n log n,m logn}) to find a minmax strongly connected spanning subgraph of a digraph with n nodes and m arcs. A generalization of this problem called the minmax strongly connected subgraph problem with node penalties is also considered. An O(m log n) algorithm is proposed to solve this general problem. We also discuss ways to improve the average complexity of this algorithm.
