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 … Visa mer A cut C = (S,T) is a partition of V of a graph G = (V,E) into two subsets S and T. The cut-set of a cut C = (S,T) is the set {(u,v) ∈ E u ∈ S, v ∈ T} of edges that have one endpoint in S and the other endpoint in T. If s and t are … Visa mer A cut is maximum if the size of the cut is not smaller than the size of any other cut. The illustration on the right shows a maximum cut: the size of the cut is equal to 5, and there is no cut of size 6, or E (the number of edges), because the graph is not Visa mer The family of all cut sets of an undirected graph is known as the cut space of the graph. It forms a vector space over the two-element Visa mer A cut is minimum if the size or weight of the cut is not larger than the size of any other cut. The illustration on the right shows a minimum cut: the size of this cut is 2, and there is no … Visa mer The sparsest cut problem is to bipartition the vertices so as to minimize the ratio of the number of edges across the cut divided by the number of vertices in the smaller half of the … Visa mer • Connectivity (graph theory) • Graph cuts in computer vision • Split (graph theory) • Vertex separator • Bridge (graph theory) Visa mer Webb12 juni 2024 · Finding min-cut is a fundamental operation in graph theory.
