Optimal Low-Degree Hardness of Maximum Independent Set [PDF]
Mathematical Statistics and Learning, 2020 We study the algorithmic task of finding a large independent set in a sparse Erd\H{o}s-R\'{e}nyi random graph with $n$ vertices and average degree $d$. The maximum independent set is known to have size $(2 \log d / d)n$ in the double limit $n \to \infty$

Improved (In-)Approximability Bounds for d-Scattered Set
Journal of Graph Algorithms and Applications, 2023 In the $d$-${\rm S{\small CATTERED}\;S{\small ET}}$ problem we are asked to select at least $k$ vertices of a given graph, so that the distance between any pair is at least $d$.

On the Outer-Independent Double Roman Domination of Graphs
Frontiers 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 ...

1-Extendability of Independent Sets
Algorithmica, 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.

Minimization of Boolean functions in the class of orthogonal disjunctive normal forms
Informatika, 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 ...

Coloring and Maximum Weight Independent Set of Rectangles [PDF]
ACM-SIAM Symposium on Discrete Algorithms, 2020 In 1960, Asplund and Grunbaum proved that every intersection graph of axis-parallel rectangles in the plane admits an $O(\omega^2)$-coloring, where $\omega$ is the maximum size of a clique. We present the first asymptotic improvement over this six-decade-

On independent sets in hypergraphs [PDF]
Random Structures & Algorithms, 2012 AbstractThe independence number of a hypergraph H is the size of a largest set of vertices containing no edge of H. In this paper, we prove that if Hn is an n‐vertex ‐uniform hypergraph in which every r‐element set is contained in at most d edges, where , then urn:x-wiley::media:rsa20453:rsa20453-math-0004 where satisfies as .

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