WebWhat is a “cut”? A graph G = (V,E) can be partitioned into two disjoint sets, by simply removing edges connecting the two parts. The degree of dissimilarity between these two pieces can be computed as total weight of the edges that have been removed. In graph theoretic language it is called the cut: [2].
