A combinatorial strongly polynomial algorithm for minimizing submodular functions.

A combinatorial strongly polynomial algorithm for minimizing submodular functions.

This paper presents a combinatorial polynomial-time algorithm for minimizing submodular functions, answering an open question posed in 1981 by Grötschel, Lovász, and Schrijver. The algorithm employs a scaling scheme that uses a flow in the complete directed graph on the underlying set with each arc...
