摘要: 用构造方法给出图的优美标号, 并证明这五类图都是优美图. 当n≤5时, 都是极小优美图, 并给出对应长度尺子刻度数最少的15组刻度值.

关键词: 优美图, 优美标号, 完全二部图, 极小优美图, 省刻度尺

Abstract: The graceful labels of graphs were given by the construction method, and it was proved that these five kinds of graphs were all graceful graphs. When n≤5, were all extremely minimal graceful graph, from which the 15 groups of scale values with the least number of scales for the corresponding length ruler were given.

Key words: graceful graph, graceful labeling, complete bipartite graph, minimal graceful graph, saving scale
