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.

A 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 .
