We present the fastest known deterministic algorithm for finding the vertex connectivity and a corresponding separator. The time for a digraph having n vertices and m edges is O(min{κ3 + n, κn}m); for an undirected graph the term m can be replaced by κn. A randomized algorithm finds κ with error probability 1/2 in time O(nm). If the vertices have nonnegative weights the weighted vertex connectivity is found in time O(κ1nmlog(n2/m)) where κ1 ≤ m/n is the unweighted vertex connectivity or in expected time O(nmlog(n2/m)) with error probability 1/2. The main algorithm combines two previous vertex connectivity algorithms and a generalization of the preflow-push algorithm of Hao and Orlin (1994, J. Algorithms17, 424–446) that computes edge connectivity.","lang":"eng"}],"extern":"1","issue":"2","oa_version":"None","title":"Computing vertex connectivity: New bounds from old techniques","publication":"Journal of Algorithms","intvolume":"        34","publication_identifier":{"issn":["0196-6774"]},"quality_controlled":"1","citation":{"apa":"Henzinger, M., Rao, S., &#38; Gabow, H.
