Two Kinds of Graceful Graphs Including K4 and Their Labeling
摘要/Abstract
摘要:
利用计算机为辅助工具,分别给出了2类包含图K4的图K4+Gn+1和K4+Gn,n的优美标号,从而证明了图K4+Gn+1,n是优美图,并由K4+Gn,n的优美性给出了边数为m的极小优美图的顶点数f(m)的范图是{(1+8m+1)/2}≤f(m)≤{2(m+3-10}.
Abstract:
The graceful labelings of two kinds of graphs including K4 was gaven.One is K4+G n+1graphs,the other is K4+G n+1 graph's.So,it's proved that K4+G n+1 graph and K4+Kn,n graph are graceful graphs ,and according to K4+Kn,ngraph's graceful given to the range of the vertes f(m)of the lest graceful graph of edge m is{(1+8m+1)/2}≤f(m)≤{2(m+3-10}.
