Plummeting Broadcast Storm Problem in Highways by Clustering Vehicles Using Dominating Set and Set Cover [PDF]
“Vehicular Ad-hoc Networks„ (VANETs): As an active research area in the field of wireless sensor networks, they ensure road safety by exchanging alert messages about unexpected events in a decentralized manner.

Knapsack with Vertex Cover, Set Cover, and Hitting Set [PDF]
Given an undirected graph $\mathcal{G}=(\mathcal{V},\mathcal{E})$, with vertex weights $(w(u))_{u\in\mathcal{V}}$, vertex values $(α(u))_{u\in\mathcal{V}}$, a knapsack size $s$, and a target value $d$, the \vcknapsack problem is to determine if there exists a subset $\mathcal{U}\subseteq\mathcal{V}$ of vertices such that $\mathcal{U}$ forms a vertex ...

Interactive Submodular Set Cover [PDF]
We introduce a natural generalization of submodular set cover and exact active learning with a finite hypothesis class (query learning). We call this new problem interactive submodular set cover. Applications include advertising in social networks with hidden information.

Abstract Methods for improving upper and lower bounds for various coverings of planar sets are proposed. New bounds for various numbers of partition constituents are presented, and suggestions for the generalization of the presented methods are offered.

Covering the recursive sets [PDF]
We give solutions to two of the questions in a paper by Brendle, Brooke-Taylor, Ng and Nies. Our examples derive from a 2014 construction by Khan and Miller as well as new direct constructions using martingales. At the same time, we introduce the concept of i.o. subuniformity and relate this concept to recursive measure theory.

Streaming Set Cover in Practice [PDF]
State-of-the-art practical algorithms for solving large Set Cover instances can all be regarded as variants of the Greedy Set Cover algorithm. These algorithms maintain the input sets in memory, which yields a substantial memory footprint. In particular,

Approximation Algorithm for the Minimum Hub Cover Set Problem
A subset ${\mathcal{ S}}\subseteq V$ of vertices of an undirected graph $G=(V,E)$ is a hub cover when for each edge $(u,v) \in E$ , at least one of its endpoints belongs to ${\mathcal{ S}}$ , or there exists a vertex $r \in {\mathcal{ S}}$ that ...

On covering by translates of a set [PDF]
AbstractIn this paper we study the minimal number τ(S,G) of translates of an arbitrary subset S of a group G needed to cover the group, and related notions of the efficiency of such coverings. We focus mainly on finite subsets in discrete groups, reviewing the classical results in this area, and generalizing them to a much broader context. For example,
