摘要: 用σG(v)表示图G中顶点v与G中所有顶点间的距离之和.利用σG(v)指标得到了含有割点的2-边连通图G的强定向的最小平均距离的若干下界.

关键词: 2-边连通图, 强定向, 平均距离, 割点

Abstract: Let σG(v)denotes the sum of the distance between the vertex of and all of the vertices of G.By making use of the σG(v)index,some lower bounds on the minimum average distance of all strong orientations of a 2-edge connected graph G with at least a cut vertex were established.

Key words: 2-edge connected graph, strong orientation, average distance, cut vertex
