Computing The Irregularity Strength of Planar Graphs

open access: yesMathematics, 2018
The field of graph theory plays a vital role in various fields. One of the important areas in graph theory is graph labeling used in many applications such as coding theory, X-ray crystallography, radar, astronomy, circuit design, communication network ...

Prime labeling in the context of web graphs without center

open access: yesAKCE International Journal of Graphs and Combinatorics, 2021
A prime labeling on a graph G of order n is a bijection from the set of vertices of G into the set of first n positive integers such that any two adjacent vertices in G have relatively prime labels.

A Unified Graph Labeling Algorithm for Consecutive-Block Channel Allocation in SC-FDMA

open access: yesIEEE Transactions on Wireless Communications, 2013
Optimal channel allocation is a key performance engineering aspect in single-carrier frequency-division multiple access (SC-FDMA). In SC-FDMA with localized channel assignment, the channels of each user must form a consecutive block.

α_{2}-labeling of graphs [PDF]

open access: yesOpuscula Mathematica, 2009
We show that if a graph \(G\) on \(n\) edges allows certain special type of rosy labeling (a.k.a. \(\rho\)-labeling), called \(\alpha_2\)-labeling, then for any positive integer \(k\) the complete graph \(K_{2nk+1}\) can be decomposed into copies of \(G\)

- and -labeling problems on interval graphs

open access: yesAKCE International Journal of Graphs and Combinatorics, 2017
For a given graph , the - and -labeling problems assign the labels to the vertices of . Let be the set of non-negative integers. An - and -labeling of a graph is a function such that , for respectively, where represents the distance (minimum number of ...

Graceful Labeling For bipartite graceful Graphs and related Graphs [PDF]

open access: yesarXiv, 2020
The concept of graceful labels was proposed by Rosa, scholars began to study graceful labels of various graphs and obtained relevant results.Let the graph is a bipartite graceful graph, we have proved some graphs are graceful labeling in this paper.

Even vertex $ζ$-graceful labeling on Rough Graph [PDF]

open access: yesarXiv, 2022
Rough graph is the graphical structure of information system with imprecise knowledge. Tong He designed the properties of rough graph in 2006[6] and following that He and Shi introduced the notion of edge rough graph[7]. He et al developed the concept of weighted rough graph with weighted attributes[6].

Fast approximate energy minimization via graph cuts

open access: yesProceedings of the Seventh IEEE International Conference on Computer Vision, 2001
In this paper we address the problem of minimizing a large class of energy functions that occur in early vision. The major restriction is that the energy function's smoothness term must only involve pairs of pixels.

Total Face Irregularity Strength of Grid and Wheel Graph under K-Labeling of Type (1, 1, 0)

open access: yesJournal of Mathematics, 2021
In this study, we used grids and wheel graphs G=V,E,F, which are simple, finite, plane, and undirected graphs with V as the vertex set, E as the edge set, and F as the face set.

Novel Properties of Fuzzy Labeling Graphs

open access: yesJournal of Mathematics, 2014
The concepts of fuzzy labeling and fuzzy magic labeling graph are introduced. Fuzzy magic labeling for some graphs like path, cycle, and star graph is defined. It is proved that every fuzzy magic graph is a fuzzy labeling graph, but the converse is not
