Radio Heronian Mean k-Graceful Labeling on Degree Splitting of Graphs

open access: yesRatio Mathematica, 2023
A mapping g:V\left(G\right)\rightarrow{k,k+1,\ldots,k+N-1} is a radio heronian mean k-labeling such that if for any two distinct vertices s and t of G, d\left(s,t\right)+\left\lceil\frac{g\left(s\right)+g\left(t\right)+\sqrt{g\left(s\right)g\left(t\right)

On the Graceful Game [PDF]

open access: yes, 2020
A graceful labeling of a graph $G$ with $m$ edges consists of labeling the vertices of $G$ with distinct integers from $0$ to $m$ such that, when each edge is assigned as induced label the absolute difference of the labels of its endpoints, all induced ...

Improper Graceful and Odd-graceful Labellings of Graph Theory

open access: yesCoRR, 2015
In this paper we define some new labellings for trees, called the in-improper and out-improper odd-graceful labellings such that some trees labelled with the new labellings can induce graceful graphs having at least a cycle. We, next, apply the new labellings to construct large scale of graphs having improper graceful/odd-graceful labellings or having ...

Applications of mathematical programming in graceful labeling of graphs

open access: yesJournal of Applied Mathematics, 2004
Graceful labeling is one of the best known labeling methods of graphs. Despite the large number of papers published on the subject of graph labeling, there are few particular techniques to be used by researchers to gracefully label graphs. In this paper,

Expanding graceful trees

open access: yesElectronic Journal of Graph Theory and Applications, 2020
Two methods for expanding graceful trees are introduced. In constructing a larger graceful trees, these methods are based on a collection of certain graceful trees and one graceful tree as the core of the produced graceful tree.

Special Graceful Labelings of Irregular Fences and Lobsters

open access: yesUniversal Journal of Mathematics and Applications, 2019
Irregular fences are subgraphs of $P_m \times P_n$ formed with $m$ copies of $P_n$ in such a way that two consecutive copies of $P_n$ are connected with one or two edges; if two edges are used, then they are located in levels separated an odd number of ...
