Independent partial domination

open access: yesCubo, 2021
For $p\in(0,1]$, a set $S\subseteq V$ is said to $p$-dominate or partially dominate a graph $G = (V, E)$ if $\frac{|N[S]|}{|V|}\geq p$. The minimum cardinality among all $p$-dominating sets is called the $p$-domination number and it is denoted by ...

Extremal Independent Set Reconfiguration

open access: yesThe Electronic Journal of Combinatorics, 2023
The independent set reconfiguration problem asks whether one can transform one given independent set of a graph into another, by changing vertices one by one in such a way the intermediate sets remain independent. Extremal problems on independent sets are widely studied: for example, it is well known that an $n$-vertex graph has at most $3^{n/3 ...

1-Extendability of Independent Sets

open access: yesAlgorithmica, 2022
Abstract In the 70s, Berge introduced 1-extendable graphs (also called B-graphs), which are graphs where every vertex belongs to a maximum independent set. Motivated by an application in the design of wireless networks, we study the computational complexity of 1-extendability, the problem of deciding whether a graph is 1-extendable.

On the Outer-Independent Double Roman Domination of Graphs

open access: yesFrontiers in Applied Mathematics and Statistics, 2021
An outer-independent double Roman dominating function (OIDRDF) of a graph G is a function h:V(G)→{0,1,2,3} such that i) every vertex v with f(v)=0 is adjacent to at least one vertex with label 3 or to at least two vertices with label 2, ii) every vertex ...

Minimization of Boolean functions in the class of orthogonal disjunctive normal forms

open access: yesInformatika, 2021
The orthogonal disjunctive normal forms (DNFs) of Boolean functions have wide applications in the logical design of discrete devices. The problem of DNF orthogonalization is to get for a given function such a DNF that any two its terms would be ...

The hardness of the independence and matching clutter of a graph [PDF]

open access: yesOpuscula Mathematica, 2016
A clutter (or antichain or Sperner family) \(L\) is a pair \((V,E)\), where \(V\) is a finite set and \(E\) is a family of subsets of \(V\) none of which is a subset of another.

Stability for Maximal Independent Sets [PDF]

open access: yesThe Electronic Journal of Combinatorics, 2020
Answering questions of Y. Rabinovich, we prove "stability" versions of upper bounds on maximal independent set counts in graphs under various restrictions. Roughly these say that being close to the maximum implies existence of a large induced matching or triangle matching (depending on assumptions).

Independent Dominating Set on Chain of Fuzzy Graphs

open access: yesTikrit Journal of Pure Science, 2023
             In this paper, we applied some properties on chain fuzzy graphs, which comprise vertex identification. These properties are independent sets and independent dominant sets.

Edge Metric Dimension and Edge Basis of One-Heptagonal Carbon Nanocone Networks

open access: yesIEEE Access, 2022
A molecular (chemical) graph is a simple connected graph, where the vertices represent the compound’s atoms and the edges represent bonds between the atoms, and the degree (valence) of every vertex (atom) is not more than four.
