WebAug 23, 2024 · Cut Set of a Graph Let 'G'= (V, E) be a connected graph. A subset E' of E is called a cut set of G if deletion of all the edges of E' from G makes G disconnect. If deleting a certain number of edges from a graph makes it disconnected, then those deleted edges are called the cut set of the graph. Example Take a look at the following graph.

In this tutorial, we’ll discuss the cut property in a minimum spanning tree. Furthermore, we’ll present several examples of cut and also discuss the correctness of cut property in a minimum spanning tree. See more In graph theory, a cut can be defined as a partition that divides a graph into two disjoint subsets. Let’s define a cut formally.

We’ll also demonstrate how to find a cut set, cut vertex, and cut edge. First, let’s take a look at a … See more 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.
