有向图C(向量)n×P(向量)2的优美性
On the Gracefulness of the Digraph C(向量)n×P(向量)2
【摘要】 研究了有向C(向量)n×P(向量)2的优美性,利用搜索图的标号的算法与数学证明相结合的方法,证实了有向图C(向量)n×P(向量)2为优美图,其中n为任意正整数.
【Abstract】 In the paper,discusses the gracefulness of the digraph,using the algorithm for searching graph labeling combining with mathematical prove,we verify that the digraph Cn X P2 is graceful and n is any positive integer.
