Graceful labeling of graphs
Webgraphs are graceful. Another significant labeling is a α-labeling or α-valuation which was additionally presented by Rosa [90]. A α-valuation of a graph G is a graceful valuation of G which likewise fulfills the accompanying condition: there exists a number γ (0 ≤ γ 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.

WebExploring Graph Theory. This research project is in the mathematical area of graph theory, where a graph is a mathematical representation of relationships among entities. Formally, we describe it as a structure consisting of a collection of points, called vertices, and lines, called edges, joining pairs of points. In particular, we will focus on a type of graph … WebJan 6, 2024 · In this paper, an efficient encryption process using Trifid Cipher accompanied with Graceful Labeling is elaborated. The Trifid Cipher is a trigraphic cipher which uses a 3x3x3 key cube for plaintext encryption and combines the concepts of Substitution cipher along with Transposition and Fractionation techniques making it highly resistant to …
WebA graceful labeling of a graph G = (V, E) is an assignment of labels to the vertices V of G subject to constraints arising from the structure of the graph. A graph is called graceful … WebApr 8, 2015 · Solairaju and Chithra introduced a new type of labeling of a graph G with p vertices and q edges called an edge odd graceful labeling if there is a bijection f from the edges of the graph to the ...
WebJun 16, 2024 · The complementary graceful labeling \(\overline{f}\) of the graph G of Figure 2.1 is also shown in the figure. Another example of a graceful graph is the famous Petersen graph. A graceful labeling of this graph is shown in Figure 2.3. 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 .
