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 … In graph theory, a cut is a partition of the vertices of a graph into two disjoint subsets. Any cut determines a cut-set, the set of edges that have one endpoint in each subset of the partition. These edges are said to cross the cut. In a connected graph, each cut-set determines a unique cut, and in some cases cuts are identified with their cut-sets rather than with their vertex partitions. In a flow network, an s–t cut is a cut that requires the source and the sink to be in different subsets…
