WebCut (graph theory) In graph theory, a cut is a partition of the vertices of a graph into two disjoint subsets. [1] 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 ...
