Dominating set games [PDF]

open access: yesOperations Research Letters, 2004
This paper presents several representation theorems for the solubility of three cost allocation problems, which are presented as cooperative games. In each problem, a graph \(G = (V, E)\) is given along with a cost function: given \(S \subseteq V\), \(c(S)\) is the cost of \(k\)-dominating the vertices in \(S\), i.e., building a set \(K \subseteq V ...

A Linear Kernel for Planar Total Dominating Set [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2018
A total dominating set of a graph $G=(V,E)$ is a subset $D \subseteq V$ such that every vertex in $V$ is adjacent to some vertex in $D$. Finding a total dominating set of minimum size is NP-hard on planar graphs and W[2]-complete on general graphs when ...

The complexity of dominating set reconfiguration [PDF]

open access: green, 2015
Suppose that we are given two dominating sets $D_s$ and $D_t$ of a graph $G$ whose cardinalities are at most a given threshold $k$. Then, we are asked whether there exists a sequence of dominating sets of $G$ between $D_s$ and $D_t$ such that each ...

DOMINATION AND EDGE DOMINATION IN TREES

open access: yesUral Mathematical Journal, 2020
Let \(G=(V,E)\) be a simple graph. A set \(S\subseteq V\) is a dominating set if every vertex in \(V \setminus S\) is adjacent to a vertex in \(S\).

On Hop Roman Domination in Trees [PDF]

open access: yesCommunications in Combinatorics and Optimization, 2019
Let $G=(V,E)$ be a graph. A subset $S\subset V$ is a hop dominating set if every vertex outside $S$ is at distance two from a vertex of $S$. A hop dominating set $S$ which induces a connected subgraph is called a connected hop dominating set of $G$.

Connected End Anti-Fuzzy Equitable Dominating Set In Anti-Fuzzy Graphs

open access: yesRatio Mathematica, 2023
In this paper, the notion of connected end anti-fuzzy equitable dominating set of an anti-fuzzy graph is discussed. The connected end anti-fuzzy equitable domination number for some standard graphs are obtained.

Dominating Sets and Connected Dominating Sets in Dynamic Graphs [PDF]

open access: yes, 2019
In this paper we study the dynamic versions of two basic graph problems: Minimum Dominating Set and its variant Minimum Connected Dominating Set. For those two problems, we present algorithms that maintain a solution under edge insertions and edge deletions in time $O( \cdot \text{polylog}~n)$ per update, where $ $ is the maximum vertex degree in the

Dominating Sets and Domination Polynomials of Paths [PDF]

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2009
Let G = (V, E) be a simple graph. A set S⊆V is a dominating set of G, if every vertex in V\S is adjacent to at least one vertex in S. Let be the family of all dominating sets of a path Pn with cardinality i, and let . In this paper, we construct , and obtain a recursive formula for d(Pn, i).

New Results on Directed Edge Dominating Set [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2023
We study a family of generalizations of Edge Dominating Set on directed graphs called Directed $(p,q)$-Edge Dominating Set. In this problem an arc $(u,v)$ is said to dominate itself, as well as all arcs which are at distance at most $q$ from $v$, or at ...
