Web如图1所示，点分割是将图的结点分配到各个子图中，维持结点之间子图的完整性，这个时候可能造成某些结点之间的边被切掉(edge-cut)；同理边分割是将图的边分配到各个子图中，每组分配的边构成子图，这个时候造成某 … hout profielenhout productenIn 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 … See more 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 … See more 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 See more 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 finite field of arithmetic modulo two, with the symmetric difference of two cut sets as the vector addition operation, and is the See more A cut is minimum if the size or weight of the cut is not larger than the size of any other cut.
