WebA minimum cut algorithm determines one of them as well as the min-cut weight. Directed Graphs Given a directed graph G = ( V , E ), a cut of G is a partition of the vertices into two, non-empty sets S and T where S is known as the set of source vertices and T is known as the set of sink vertices . In graph theory, a minimum cut or min-cut of a graph is a cut (a partition of the vertices of a graph into two disjoint subsets) that is minimal in some metric. Variations of the minimum cut problem consider weighted graphs, directed graphs, terminals, and partitioning the vertices into more than two sets. The weighted min-cut problem allowing both positive and negative weights ca…
