查询词典 transitive graph

If the vertex set of a graph can be partitioned into two disjoint nonempty sets V_(1) and V_(2), every vertex in V_(1) connects every vertex in V_(2) and there is no edge in V_(1) and V_(2), then we call this graph is a complete bipartite graph. If V_(1) contains m elements and V_(2) contains n elements, then we denote this complete bipartite graph K_.

当一个图中的点集合可以分成两个非空的集合V_(1)及V_(2)，若 V_(1)中的每一点都与V_(2)中的点有边相连，且在V_(1)及V_(2)中的点都没有边相连，则称此图为完全二分图；若 V_(1)中有m个点，V_(2)中有n个点，则此完全二分图记为K_。
