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 . Thus, a graph G = (V, E) is graceful if and only if there exists a… WebAug 15, 2024 · A graceful graph is a graph that can be gracefully labeled.
