Graceful labeling of graphs
WebIf the given graph G is graceful this algorithm generates a graceful labeling. If the algorithm fails to generate such a labeling it is proved that G is not graceful. Theorem 1. … WebMay 25, 1999 · Graceful Graph A Labeled Graph which can be ``gracefully numbered'' is called a graceful graph. Label the nodes with distinct Nonnegative Integers. Then label the Edges with the absolute differences between node values. If the Edge numbers then run from 1 to , the graph is gracefully numbered.

The name "graceful labeling" is due to Solomon W. Golomb; this type of labeling was originally given the name β-labeling by Alexander Rosa in a 1967 paper on graph labelings.

WebA graph is known as graceful when its vertices are labeled from 0 to E , the size of the graph, and this labelling induces an edge labelling from 1 to E . For any edge e, the label of e is the positive difference between the two vertices incident with e. In other words, if e is incident with vertices labeled i and j, e will be labeled i − j . WebMar 12, 2024 · A graceful labeling of a graph G with n edges is an injective function f : V (G) \rightarrow \ {0, 1, \ldots , n\} such that when each edge x — y \in E (G) is assigned the edge label, f (x)-f (y) , all the edge labels are distinct. A graph is said to be graceful if it admits a graceful labeling.
