Eternal Domination: Criticality and Reachability [PDF]

open access: yesDiscussiones Mathematicae Graph Theory, 2017
We show that for every minimum eternal dominating set, D, of a graph G and every vertex v ∈ D, there is a sequence of attacks at the vertices of G which can be defended in such a way that an eternal dominating set not containing v is reached.

A linear Algorithm For The Eternal Feedback Vertex Set on Interval Graphs*

open access: yes, 2023
International audienceThe Eternal Feedback Vertex Set problem is a new model of protecting graphs using mobile guards, which is usually modeled using a two-players game; a defender and an attacker.

Approximation hardness of dominating set problems in bounded degree graphs [PDF]

open access: yes, 2008
We study approximation hardness of the Minimum Dominating Set problem and its variants in undirected and directed graphs. Using a similar result obtained by Trevisan for Minimum Set Cover we prove the first explicit approximation lower bounds for various

Positive Influence Dominating Set in E-Learning Social Networks [PDF]

open access: yes, 2011
In recent years, the development of E-learning is rapid. Learning efficiency can be greatly improved if E-learning users' social networks properties can be effectively utilized. However, the nodes in most research models are the same type.

Positive Influence Dominating Set Games

open access: yes, 2014
Motivated by applications in social networks, a new type of dominating set named Positive Influence Dominating Set (PIDS) has been studied in the literature. In this paper, we investigate cooperative cost games arising from PIDS problem on social network
