Some results on Steiner decomposition number of graphs

open access: yesKuwait Journal of Science, 2023
Let $G$ be a connected graph with Steiner number $s(G)$. A decomposition $\pi=\{G_1, G_2,..., G_n\}$ is said to be a Steiner decomposition if $s(G_i)=s(G)$ for all $i\:(1\leq i\leq n)$. The maximum cardinality obtained for the Steiner decomposition $\pi$

The Spectrum Problem for the Connected Cubic Graphs of Order 10

open access: yesDiscussiones Mathematicae Graph Theory, 2021
We show that if G is a connected cubic graph of order 10, then there exists a G-decomposition of Kv if and only if v ≣ 1 or 10 (mod 15) except when v = 10 and G is one of 5 specific graphs.

Local Balance in Graph Decompositions [PDF]

open access: yesGraphs and Combinatorics, 2022
In a balanced graph decomposition, every vertex of the host graph appears in the same number of blocks. We propose the use of colored loops as a framework for unifying various other types of local balance conditions in graph decompositions. In the basic case where a single graph with colored loops is used as a block, an existence theory for such ...

Edge-partitioning graphs into regular and locally irregular components [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2016
A graph is locally irregular if every two adjacent vertices have distinct degrees. Recently, Baudon et al. introduced the notion of decomposition into locally irregular subgraphs.

On tree-decompositions of one-ended graphs [PDF]

open access: yes, 2018
A graph is one-ended if it contains a ray (a one way infinite path) and whenever we remove a finite number of vertices from the graph then what remains has only one component which contains rays. A vertex $v$ {\em dominates} a ray in the end if there are

Structural Decomposition Model for the Evolution of AS-Level Internet Topologies

open access: yesIEEE Access, 2020
Modeling Internet graphs at the autonomous-system (AS) level is helpful for recognizing and predicting the development trend of evolving Internet topology from a macro perspective.

Optimizing tree decompositions in MSO [PDF]

open access: yesLogical Methods in Computer Science, 2022
The classic algorithm of Bodlaender and Kloks [J. Algorithms, 1996] solves the following problem in linear fixed-parameter time: given a tree decomposition of a graph of (possibly suboptimal) width k, compute an optimum-width tree decomposition of the ...

Low Diameter Graph Decompositions by Approximate Distance Computation [PDF]

open access: yes, 2019
In many models for large-scale computation, decomposition of the problem is key to efficient algorithms. For distance-related graph problems, it is often crucial that such a decomposition results in clusters of small diameter, while the probability that ...

A C3 Magic Decomposition on Friendship Graph with Odd Order

open access: yesJurnal Ilmu Dasar, 2022
Let G = (V,E) is graph with a non-empty set V containing vertices and a set of edges E. Also note that if H = {H_i⊆G_i = 1,2,3,...,n} is a collection of subgraphs from G with H_i≅Hj,i ≠ j.
