Graceful and Antimagic Labelings

2019
This chapter explores the relationship between antimagic labeling and alpha labelings and also the well-known graceful labelings. Much of this chapter looks at interesting labelings and structures on trees, including edge antimagic trees, alpha trees, and disjoint union of caterpillars.

Ordered Graceful Labellings of the 2-Star

open access: yesDiscrete Mathematics, 2001
The authors investigate ordered graceful labellings of 2-stars. They give a lower bound on the number of non-equivalent ordered graceful labellings by constructing an exponential number of such labellings. This shows that a conjecture of Cahit is false.

The Generation of k-Graceful Figure and Graceful Label

2014 Fourth International Conference on Instrumentation and Measurement, Computer, Communication and Control, 2014
This paper introduces the concept of graceful figure, discusses a special kind of graceful figure: K-graceful figure, draw all the graceful figure of the generated by the n side of all the beautiful label generation algorithm. The algebraic theory and computer tools introduced a graceful figure.

On Graceful Labelings of Trees

2011
A tree is a connected acyclic graph. A tree of n vertices is said to be graceful if the vertices can be assigned the labels {0, 1, 2, ..., n - 1} such that the absolute value of the differences in vertex labels between neighboring vertices generate the set consisting distinct values {1, 2, 3, ...,n-1}.

Graceful Labelings of Nearly Complete Graphs

Results in Mathematics, 2002
A graph with \(q\) edges is graceful, if we can assign to each vertex an integer in \(\{0, 1, \ldots, q\}\), such that all edges have a different value of the absolute difference of the labels of its endpoints. This paper investigates which graphs that are `nearly complete', or a complete multipartite graph, are graceful.

Graceful labeling based En (Grace) cryption and De (Grace) cryption

2013 IEEE International Conference ON Emerging Trends in Computing, Communication and Nanotechnology (ICECCN), 2013
In recent years, Encryption has fascinated extra responsiveness owing to the swift development in multimedia and network technologies where the data has to be shielded from unauthorized access. Image scrambling scheme provide protection for digital images.

On graceful and cordial labeling of shell graphs.

Ars Comb., 2011
A graceful labeling, an \(\alpha \)-labeling (called here \(\Delta \)-labeling), and a cordial labeling of yet another special class of graphs are provided. Unfortunately, the paper contains many typographical, grammatical and stylistic errors.

A Metaheuristic Approach to the Graceful Labeling Problem

International Journal of Applied Metaheuristic Computing, 2010
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, such that each edge is uniquely identified by the absolute difference between its endpoints.
