Weighted Domination of Independent Sets [PDF]

open access: yesGraphs and Combinatorics, 2019
The {\em independent domination number} $ ^i(G)$ of a graph $G$ is the maximum, over all independent sets $I$, of the minimal number of vertices needed to dominate $I$. It is known \cite{abz} that in chordal graphs $ ^i$ is equal to $ $, the ordinary domination number.

On the parameterized complexity of approximating dominating set [PDF]

open access: yesElectron. Colloquium Comput. Complex., 2017
We study the parameterized complexity of approximating the k-Dominating Set (domset) problem where an integer k and a graph G on n vertices are given as input, and the goal is to find a dominating set of size at most F(k) · k whenever the graph G has a ...

Perfect Outer-connected Domination in the Join and Corona of Graphs

open access: yesRecoletos Multidisciplinary Research Journal, 2016
Let 𝐺 be a connected simple graph. A dominating set 𝑆 ⊆ 𝑉(𝐺) is called a perfect dominating set of 𝐺 if each 𝑢 ∈ 𝑉 𝐺 ∖ 𝑆 is dominated by exactly one element of 𝑆.

Hereditary Equality of Domination and Exponential Domination in Subcubic Graphs

open access: yesDiscussiones Mathematicae Graph Theory, 2021
Let γ(G) and γe(G) denote the domination number and exponential domination number of graph G, respectively. Henning et al., in [Hereditary equality of domination and exponential domination, Discuss. Math. Graph Theory 38 (2018) 275–285] gave a conjecture:

A Survey on Domination in Vague Graphs with Application in Transferring Cancer Patients between Countries

open access: yesMathematics, 2021
Many problems of practical interest can be modeled and solved by using fuzzy graph (FG) algorithms. In general, fuzzy graph theory has a wide range of application in various fields. Since indeterminate information is an essential real-life problem and is

Kernelization and Sparseness: the case of Dominating Set [PDF]

open access: yes, 2015
We prove that for every positive integer $r$ and for every graph class $\mathcal G$ of bounded expansion, the $r$-Dominating Set problem admits a linear kernel on graphs from $\mathcal G$.

A Note on the Locating-Total Domination in Graphs

open access: yesDiscussiones Mathematicae Graph Theory, 2017
In this paper we obtain a sharp (improved) lower bound on the locating-total domination number of a graph, and show that the decision problem for the locating-total domination is NP-complete.

A Dual Attack Detection Technique to Identify Black and Gray Hole Attacks Using an Intrusion Detection System and a Connected Dominating Set in MANETs

open access: yesFuture Internet, 2019
A mobile ad-hoc network (MANET) is a temporary network of wireless mobile nodes. In a MANET, it is assumed that all of the nodes cooperate with each other to transfer data packets in a multi-hop fashion. However, some malicious nodes don’t cooperate with

Making a Dominating Set of a Graph Connected

open access: yesDiscussiones Mathematicae Graph Theory, 2018
Let G = (V,E) be a graph and S ⊆ V. We say that S is a dominating set of G, if each vertex in V \ S has a neighbor in S. Moreover, we say that S is a connected (respectively, 2-edge connected or 2-connected) dominating set of G if G[S] is connected ...
