Solving the k-dominating set problem on very large-scale networks

open access: yesComputational Social Networks, 2020
The well-known minimum dominating set problem (MDSP) aims to construct the minimum-size subset of vertices in a graph such that every other vertex has at least one neighbor in the subset.

Disjoint Secure Domination in the Join of Graphs

open access: yesRecoletos Multidisciplinary Research Journal, 2016
Let G = (V(G),E(G)) be a simple connected graph. A dominating set S in G is called a secure dominating set in G if for every u ∈ V (G) \ S, there exists v ∈ S ∩ NG(u) such that (S \ {v}) ∪ {u} is a dominating set.

Inverse Clique Domination in Graphs

open access: yesRecoletos Multidisciplinary Research Journal, 2016
Let G be a connected simple graph. A nonempty subset S of the vertex set V (G) is a clique in G if the graph induced by S is complete. A clique S in G is a clique dominating set if it is a dominating set.

On Two Open Problems on Double Vertex-Edge Domination in Graphs

open access: yesMathematics, 2019
A vertex v of a graph G = ( V , E ) , ve-dominates every edge incident to v, as well as every edge adjacent to these incident edges. A set S ⊆ V is a double vertex-edge dominating set if every edge of E is ve-dominated by at least two

On Resolvability- and Domination-Related Parameters of Complete Multipartite Graphs

open access: yesMathematics, 2022
Graphs of order n with fault-tolerant metric dimension n have recently been characterized.This paper points out an error in the proof of this characterization. We show that the complete multipartite graphs also have the fault-tolerant metric dimension n,

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 ...

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:

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.
