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."}],"article_type":"original","_id":"11683","oa_version":"None","intvolume":"        34","extern":"1","status":"public","language":[{"iso":"eng"}],"doi":"10.1006/jagm.1999.1055","date_created":"2022-07-28T08:56:10Z","page":"222-250","day":"01","date_updated":"2022-09-12T09:06:48Z","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","date_published":"2000-02-01T00:00:00Z","title":"Computing vertex connectivity: New bounds from old techniques"}
