Succinct Representation of Labeled Graphs [PDF]

open access: yesAlgorithmica, 2007
In many applications, the properties of an object being modeled are stored as labels on vertices or edges of a graph. In this paper, we consider succinct representation of labeled graphs. Our main results are the succinct representations of labeled and multi-labeled graphs (we consider vertex labeled planar triangulations, as well as edge labeled ...

On Prime Index of a Graph

open access: yesRatio Mathematica, 2023
In prime labeling, vertices are labeled from 1 to n, with the condition that any two adjacent vertices have relatively prime labels. Coprime labeling maintains the same criterion as prime labeling with adjacent vertices using any set of distinct positive

Near-optimal adjacency labeling scheme for power-law graphs [PDF]

open access: yes, 2015
An adjacency labeling scheme is a method that assigns labels to the vertices of a graph such that adjacency between vertices can be inferred directly from the assigned label, without using a centralized data structure.

GPT-GNN: Generative Pre-Training of Graph Neural Networks [PDF]

open access: yesKnowledge Discovery and Data Mining, 2020
Graph neural networks (GNNs) have been demonstrated to be powerful in modeling graph-structured data. However, training GNNs requires abundant task-specific labeled data, which is often arduously expensive to obtain.

Minimal Sum Labeling of Graphs [PDF]

open access: yesJournal of Discrete Algorithms, 2018
A graph $G$ is called a sum graph if there is a so-called sum labeling of $G$, i.e. an injective function $\ell: V(G) \rightarrow \mathbb{N}$ such that for every $u,v\in V(G)$ it holds that $uv\in E(G)$ if and only if there exists a vertex $w\in V(G)$ such that $\ell(u)+\ell(v) = \ell(w)$. We say that sum labeling $\ell$ is minimal if there is a vertex

Gaussian Tribonacci R-Graceful Labeling of Some Tree Related Graphs

open access: yesRatio Mathematica, 2022
Let r be any natural number. An injective function , where  is the Gaussian Tribonacci number in the Gaussian Tribonacci sequence is said to be Gaussian Tribonacci r-graceful labeling if the induced edge labeling such that  is bijective.

Regular graphs of odd degree are antimagic [PDF]

open access: yes, 2013
An antimagic labeling of a graph $G$ with $m$ edges is a bijection from $E(G)$ to $\{1,2,\ldots,m\}$ such that for all vertices $u$ and $v$, the sum of labels on edges incident to $u$ differs from that for edges incident to $v$.

On the reflexive edge strength of the circulant graphs

open access: yesAIMS Mathematics, 2021
A labeling of a graph is an assignment that carries some sets of graph elements into numbers (usually the non negative integers). The total k-labeling is an assignment fe from the edge set to the set {1,2,...,ke} and assignment fv from the vertex set to ...

On a labeling problem in graphs

open access: yesDiscrete Applied Mathematics, 2011
AbstractMotivated by applications in software programming, we consider the problem of covering a graph by a feasible labeling. Given an undirected graph G=(V,E), two positive integers k and t, and an alphabet Σ, a feasible labeling is defined as an assignment of a set Lv⊆Σ to each vertex v∈V, such that (i) |Lv|≤k for all v∈V and (ii) each label α∈Σ is ...
