In this case, the capacity of the cut is the sum the capacity of each edge and vertex in it.

WebFeb 26, 2024 · Each of the spanning trees has the same weight equal to 2.. Cut property:. For any cut C of the graph, if the weight of an edge E in the cut-set of C is strictly smaller than the weights of all other edges of the … 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… bucks appliance loyalton ca
