On Independence Domination
نویسندگان
چکیده
Let G be a graph. The independence-domination number γ(G) is the maximum over all independent sets I in G of the minimal number of vertices needed to dominate I. In this paper we investigate the computational complexity of γ(G) for graphs in several graph classes related to cographs. We present an exact exponential algorithm. We also present a PTAS for planar graphs.

Mixed Roman domination and 2-independence in trees
Let $G=(V, E)$ be a simple graph with vertex set $V$ and edge set $E$. A {em mixed Roman dominating function} (MRDF) of $G$ is a function $f:Vcup Erightarrow {0,1,2}$ satisfying the condition that every element $xin Vcup E$ for which $f(x)=0$ is adjacentor incident to at least one element $yin Vcup E$ for which $f(y)=2$. The weight of anMRDF $f$ is $sum _{xin Vcup E} f(x)$. The mi...
متن کاملIndependence Saturation and Extended Domination Chain in Graphs
The six basic parameters relating to domination, independence and irredundance satisfy a chain of inequalities given by ir ≤ γ ≤ i ≤ β0 ≤ Γ ≤ IR where ir, IR are the irredundance and upper irredundance numbers, γ,Γ are the domination and upper domination numbers and i, β0 are the independent domination number and independence number respectively. In this paper, we introduce the concept of indep...
متن کاملPrice of Independence for the Dominating Set Problem
Let γ(G) and ι(G) be the domination and independent domination numbers of a graph G, respectively. In this paper, we define the Price of Independence of a graph G as the ratio ι(G) γ(G) . Firstly, we bound the Price of Independence by values depending on the number of vertices. Secondly, we consider the question of computing the Price of Independence of a given graph. Unfortunately, the decisio...
متن کاملParameters of independence and domination by monochromatic paths in graphs
In this paper we generalize parameters of independence and domination for graphs. The behavior of parameters for independence and domination by monochromatic paths is studied when an edge or a vertex is deleted. Then we give main results concerning μ-feasible sequences and interpolation.
متن کاملGeneralised Domination and Independence in Graphs
In this paper, we introduce a new scheme of parameters which generalises many wellknown parameters, including the domination number, the total domination number, the independence number, and the vertex covering number.
متن کاملGraffiti.pc on the 2-domination number of a graph
The k-domination number γk(G) of a simple, undirected graph G is the order of a smallest subset D of the vertices of G such that each vertex of G is either in D or adjacent to at least k vertices in D. In 2010, the conjecture-generating computer program, Graffiti.pc, was queried for upperbounds on the 2-domination number. In this paper we prove new upper bounds on the 2-domination number of a g...
