This natural family of discrete functions includes submodular and bisubmodular functions as the special cases k = 1 and k = 2 respectively.\r\n\r\nIn particular we generalize the known Min-Max-Theorem for submodular and bisubmodular functions. This theorem asserts that the minimum of the (bi)submodular function can be found by solving a maximization problem over a (bi)submodular polyhedron. We define a k-submodular polyhedron, prove a Min-Max-Theorem for k-submodular functions, and give a greedy algorithm to construct the vertices of the polyhedron.\r\n"}],"main_file_link":[{"open_access":"1","url":"http://arxiv.org/abs/1309.5469"}],"department":[{"_id":"VlKo"}],"publication_status":"published","date_published":"2012-04-01T00:00:00Z","date_updated":"2021-01-12T07:00:46Z","month":"04","day":"01","type":"conference","acknowledgement":"We would like to thank Andrei Krokhin for encourag- ing our cooperation, for helpful discussions, and for his critical reading of the manuscript.\r\n","year":"2012","volume":7422,"publist_id":"3806","intvolume":"      7422","_id":"2930","language":[{"iso":"eng"}],"conference":{"location":"Athens, Greece","end_date":"2012-04-21","name":"ISCO: International Symposium on Combinatorial Optimization","start_date":"2012-04-19"},"citation":{"ieee":"A.
