An $O(\log n)$-approximation for the Set Cover Problem with Set Ownership [PDF]

open access: yes, 2008
In highly distributed Internet measurement systems distributed agents periodically measure the Internet using a tool called {\tt traceroute}, which discovers a path in the network graph.

Approximating the minimum directed tree cover

open access: yes, 2010
Given a directed graph $G$ with non negative cost on the arcs, a directed tree cover of $G$ is a rooted directed tree such that either head or tail (or both of them) of every arc in $G$ is touched by $T$. The minimum directed tree cover problem (DTCP) is

The covert set-cover problem with application to Network Discovery [PDF]

open access: yes, 2012
We address a version of the set-cover problem where we do not know the sets initially (and hence referred to as covert) but we can query an element to find out which sets contain this element as well as query a set to know the elements. We want to find a

Target coverage in random wireless sensor networks using cover sets

open access: yesJournal of King Saud University: Computer and Information Sciences, 2022
There are numerous coverage algorithms which efficiently monitor targets in sensor networks by dividing the sensor network into cover sets where each cover monitors all the targets.

Amplidiff: an optimized amplicon sequencing approach to estimating lineage abundances in viral metagenomes

open access: yesBMC Bioinformatics
Background Metagenomic profiling algorithms commonly rely on genomic differences between lineages, strains, or species to infer the relative abundances of sequences present in a sample.

SCMC: An Efficient Scheme for Minimizing Energy in WSNs Using a Set Cover Approach

open access: yesFuture Internet, 2017
Energy-efficient clustering and routing are well known optimization problems in the study of Wireless Sensor Network (WSN) lifetime extension. In this paper, we propose an intelligent hybrid optimization algorithm based on a Set Cover approach to create ...

Sensor placement for fault location identification in water networks: A minimum test cover approach

open access: yes, 2016
This paper focuses on the optimal sensor placement problem for the identification of pipe failure locations in large-scale urban water systems. The problem involves selecting the minimum number of sensors such that every pipe failure can be uniquely ...

Airline crew scheduling [PDF]

open access: yes, 1992
An airline must cover each flight leg with a full complement of cabin crew in a manner consistent with safety regulations and award requirements. Methods are investigated for solving the set partitioning and covering problem.
