The algorithms output the approximate or exact size k in time O(1) or O(log n) and a cut of size k in time linear in its size. The amortized time per insertion is O(1/ε 2) for a (2+ε)-approximation, O((log λ)((log n)/ε)2) for a (1+ε)-approximation, and O(λ log n) for the exact size of the minimum edge cut, where n is the number of nodes in the graph, λ is the size of the minimum cut and ε>0. The (2+ε)-approximation algorithm and the exact algorithm are deterministic, the (1+ε)-approximation algorithm is randomized. The algorithms are optimal in the sense that the time needed for m insertions matches the time needed by the best static algorithm on a m-edge graph. We also present a static 2-approximation algorithm for the size κ of the minimum vertex cut in a graph, which takes time O(n 2 min(√n,κ)). This is a factor of κ faster than the best algorithm for computing the exact size, which takes time O(κ 2 n 2 +κ 3 n 1.5). We give an insertionsonly algorithm for maintaining a (2+ε)-approximation of the minimum vertex cut with amortized insertion time O(n(logκk)/ε).","lang":"eng"}],"publication_status":"published","year":"1995","day":"01","oa_version":"None","article_processing_charge":"No","publication_identifier":{"eissn":["1611-3349"],"isbn":["9783540494256"],"eisbn":["9783540600848"],"issn":["0302-9743"]},"doi":"10.1007/3-540-60084-1_81","quality_controlled":"1","alternative_title":["LNCS"],"language":[{"iso":"eng"}],"volume":944,"page":"280–291","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","conference":{"start_date":"1995-07-10","end_date":"1995-07-14","location":"Szeged, Hungary","name":"ICALP: International Colloquium on Automata, Languages, and Programming"},"author":[{"orcid":"0000-0002-5008-6530","last_name":"Henzinger","id":"540c9bbd-f2de-11ec-812d-d04a5be85630","first_name":"Monika H","full_name":"Henzinger, Monika H"}]}
