An improvement on the maximum number of ‐dominating independent sets [PDF]

open access: yesJournal of Graph Theory, 2018
AbstractErdős and Moser raised the question of determining the maximum number of maximal cliques or, equivalently, the maximum number of maximal independent sets in a graph on vertices. Since then there has been a lot of research along these lines.A ‐dominating independent set is an independent set such that every vertex not contained in has at ...

Domination Analysis of Greedy Heuristics For The Frequency Assignment Problem [PDF]

open access: yes, 2003
We introduce the greedy expectation algorithm for the fixed spectrum version of the frequency assignment problem. This algorithm was previously studied for the travelling salesman problem.

Independent strong domination number of indu-bala product of graphs

open access: yes, 2023
A set D⊂ V be the strong dominating set of G if every vertex in V − D is strongly dominated by at least one vertex in D. The strong domination number γst(G) of G is the minimum cardinality of a strong dominating set.

Independent domination critical and stable graphs upon edge subdivision [PDF]

open access: yes, 2007
A subset D of vertices in a graph G is an independent dominating set if D is a dominating set and an independent set. A graph is independent domination edge subdivision critical if the subdivision of an arbitrary edge increases the independent domination

Fuzzy Graphs With Equal Fuzzy Domination And Independent Domination Numbers [PDF]

open access: yes, 2013
The basic definitions of fuzzy independent set, fuzzy dominating set,and fuzzy independent dominating sets are discussed. The aim of this paper is to find on what conditions the fuzzy graph has equal domination number and independent domination number ...

Relating the Outer-Independent Total Roman Domination Number with Some Classical Parameters of Graphs [PDF]

open access: yes, 2022
For a given graph G without isolated vertex we consider a function f : V (G) -> {0,1, 2}. For every i is an element of {0,1, 2}, let V-i = {v is an element of V (G) : f (v) = i}.

Independent domination versus packing in subcubic graphs [PDF]

open access: yes, 2023
In 2011, Henning, L\"{o}wenstein, and Rautenbach observed that the domination number of a graph is bounded from above by the product of the packing number and the maximum degree of the graph.

A note on cops and robbers, independence number, domination number and diameter

open access: yesDiscrete Mathematics, 2023
We study relations between diameter $D(G)$, domination number $γ(G)$, independence number $α(G)$ and cop number $c(G)$ of a connected graph $G$, showing (i.) $c(G) \leq α(G)-\lfloor \frac{D(G)-3}{2} \rfloor$, and (ii.) $c(G) \leq γ(G) - \frac{D(G)}{3} + O (\sqrt{D(G)})$.

Independent Domination in Some Wheel Related Graphs [PDF]

open access: yes, 2016
A set S of vertices in a graph G is called an independent dominating set if S is both independent and dominating. The independent domination number of G is the minimum cardinality of an independent dominating set in G .
