Outer independent total double Italian domination number [PDF]

open access: yesComputer Science Journal of Moldova
If $G$ is a graph with vertex set $V(G)$, then let $N[u]$ be the closed neighborhood of the vertex $u\in V(G)$. A total double Italian dominating function (TDIDF) on a graph $G$ is a function $f:V(G)\rightarrow\{0,1,2,3\}$ satisfying (i) $f(N[u])\ge 3 ...

Graphs with equal Grundy domination and independence number

open access: yesDiscrete Optimization, 2023
The Grundy domination number, ${γ_{\rm gr}}(G)$, of a graph $G$ is the maximum length of a sequence $(v_1,v_2,\ldots, v_k)$ of vertices in $G$ such that for every $i\in \{2,\ldots, k\}$, the closed neighborhood $N[v_i]$ contains a vertex that does not belong to any closed neighborhood $N[v_j]$, where ...

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.

On the Number of k‐Dominating Independent Sets [PDF]

open access: yesJournal of Graph Theory, 2016
AbstractWe study the existence and the number of k‐dominating independent sets in certain graph families. While the case namely the case of maximal independent sets—which is originated from Erdős and Moser—is widely investigated, much less is known in general.

A note on the independent domination number of subset graph [PDF]

open access: yes, 1988
summary:The independent domination number $i(G)$ (independent number $\beta (G)$) is the minimum (maximum) cardinality among all maximal independent sets of $G$.

Independent Rainbow Domination Numbers of Generalized Petersen Graphs P(n,2) and P(n,3)

open access: yesMathematics, 2020
We obtain new results on independent 2- and 3-rainbow domination numbers of generalized Petersen graphs P ( n , k ) for certain values of n , k ∈ N . By suitably adjusting and applying a well established technique of tropical algebra (path

An improved upper bound on the independent double Roman domination number of trees

open access: yesAKCE International Journal of Graphs and Combinatorics, 2022
For a graph [Formula: see text] an independent double Roman dominating function (IDRDF) is a function [Formula: see text] having the property that: (i) every vertex [Formula: see text] with f(v) = 0 has a neighbor u with f(u) = 3 or at least two ...

On graphs whose domination numbers equal their independent domination numbers

open access: yesElectronic Notes in Discrete Mathematics, 2003
Abstract In this paper, we extend a result due to R. B. Allan and R. C. Laskar on graphs whose independent domination numbers equal their domination numbers. We will consider finite simple graphs as treated in most of the standard text-books on Graph Theory (e.g., see D. B. West [1]). Let G = (V,E) be any graph and D ⊆ V. We let N(D) denote the set
