Dominating Vertex Covers: The Vertex-Edge Domination Problem [PDF]

open access: yesDiscussiones Mathematicae Graph Theory, 2021
The vertex-edge domination number of a graph, γve(G), is defined to be the cardinality of a smallest set D such that there exists a vertex cover C of G such that each vertex in C is dominated by a vertex in D.

Self-Stabilizing Capacitated Vertex Cover Algorithms for Internet-of-Things-Enabled Wireless Sensor Networks [PDF]

open access: yesSensors, 2022
Wireless sensor networks (WSNs) achieving environmental sensing are fundamental communication layer technologies in the Internet of Things. Battery-powered sensor nodes may face many problems, such as battery drain and software problems.

Edge Dominating Sets and Vertex Covers

open access: yesDiscussiones Mathematicae Graph Theory, 2013
Bipartite graphs with equal edge domination number and maximum matching cardinality are characterized. These two parameters are used to develop bounds on the vertex cover and total vertex cover numbers of graphs and a resulting chain of vertex covering ...

Vertex decomposability of complexes associated to forests [PDF]

open access: yesTransactions on Combinatorics, 2022
In this article‎, ‎we discuss the vertex decomposability of three well-studied simplicial complexes associated to forests‎. ‎In particular‎, ‎we show that the bounded degree complex of a forest and the complex of directed trees of a multidiforest is ...

A Survey on the k-Path Vertex Cover Problem

open access: yesAxioms, 2022
Given an integer k ≥ 2, a k-path is a path on k vertices. A set of vertices in a graph G is called a k-path vertex cover if it includes at least one vertex of every k-path of G.

On The Study of Edge Monophonic Vertex Covering Number

open access: yesRatio Mathematica, 2022
For a connected graph G of order n ≥ 2, a set S of vertices of G is an edge monophonic vertex cover of G if S is both an edge monophonic set and a vertex covering set of G.

Multistage Vertex Cover

open access: yesTheory of Computing Systems, 2022
AbstractThe NP-complete Vertex Cover problem asks to cover all edges of a graph by a small (given) number of vertices. It is among the most prominent graph-algorithmic problems. Following a recent trend in studying temporal graphs (a sequence of graphs, so-called layers, over the same vertex set but, over time, changing edge sets), we initiate the ...

Matroid-constrained vertex cover

open access: yesTheoretical Computer Science, 2023
In this paper, we introduce the problem of Matroid-Constrained Vertex Cover: given a graph with weights on the edges and a matroid imposed on the vertices, our problem is to choose a subset of vertices that is independent in the matroid, with the objective of maximizing the total weight of covered edges.

Capacitated vertex covering [PDF]

open access: yesJournal of Algorithms, 2003
Summary: In this paper we study the capacitated vertex cover problem, a generalization of the well-known vertex cover problem. Given a graph \(G=(V,E)\) with weights on the vertices, the goal is to cover all the edges by picking a cover of minimum weight from the vertices. When we pick a copy of a vertex, we pay the weight of the vertex and cover up to
