WebIn graph theory, an edge-graceful labeling is a type of graph labeling for simple, connected graphs in which no two distinct edges connect the same two distinct vertices and no edge connects a vertex to itself. Edge-graceful labelings were first introduced by Sheng-Ping Lo in his seminal paper. [1] Definition [ edit]
Graceful labeling of graphs
Did you know?
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… WebApr 10, 2003 · In graph theory, a graceful labeling of a graph G = (V, E) with n vertices and m edges is a labeling of its vertices with distinct integers between 0 and m inclusive, …
WebOct 15, 2024 · A graph G admits a graceful labeling if there is a one-to-one map f from the set of vertices of G to { 0 , 1 , 2 , … , E ( G ) } such that when an edge xy is assigned the label f ( x ) − f ( y ) , the resulting set of edge labels is { 1 , 2 , … , E ( G ) } . When such a labeling exists, G is called graceful. Web3.1. Graceful labeling of a directed tree.
