A Combinatorial Strongly Polynomial Algorithm for. Submodular Function Minimization under Covering Constraints Satoru IwataвЃ„ Kiyohito Nagano y April 2009 Abstract This paper addresses the problems of minimizing nonnegative submodular functions, The significance of submodular features has been widely known lately in combinatorial optimization. this can be the 1st publication dedicated to the exposition of the idea of submodular features from an undemanding technical point to a sophisticated one. A unifying view of the idea is proven through base polyhedra and duality for submodular and supermodular structures. one of the matters.
