Clique versus Independent Set [PDF]
European Journal of Combinatorics, 2014 Yannakakis' Clique versus Independent Set problem (CL-IS) in communication complexity asks for the minimum number of cuts separating cliques from stable sets in a graph, called CS-separator. Yannakakis provides a quasi-polynomial CS-separator, i.e.

Beeping a Maximal Independent Set [PDF]
Distributed Computing, 2011 We consider the problem of computing a maximal independent set (MIS) in an extremely harsh broadcast model that relies only on carrier sensing. The model consists of an anonymous broadcast network in which nodes have no knowledge about the topology of ...

Independent partial domination
Cubo, 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
The 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
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.

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 ...

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 ...

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.
