Application of ant colony optimization metaheuristic on set covering problems

open access: yesMathematics in Applied Sciences and Engineering, 2022
Ant Colony Optimization (ACO) metaheuristic is a multi-agent system in which the behaviour of each ant is inspired by the foraging behaviour of real ants to solve optimization problem.

An Indirect Genetic Algorithm for Set Covering Problems [PDF]

open access: yes, 2002
This paper presents a new type of genetic algorithm for the set covering problem. It differs from previous evolutionary approaches first because it is an indirect algorithm, i.e. the actual solutions are found by an external decoder function. The genetic

Matrix Approaches for Covering-Based Multigranulation Fuzzy Rough Set Models

open access: yesJournal of Mathematics, 2023
Multigranulation rough set theory is one of the most effective tools for data analysis and mining in multicriteria information systems. Six types of covering-based multigranulation fuzzy rough set (CMFRS) models have been constructed through fuzzy β ...

Covering Arrays via Set Covers

open access: yesElectronic Notes in Discrete Mathematics, 2018
Abstract In this paper, we provide yet another construction on how to map problems pertaining covering arrays to specialized set cover problems. With this mapping it is possible to compute optimal covering arrays via minimal solutions of the generated set cover problem.

Dynamic Floating Stations Model for Emergency Medical Services with a Consideration of Traffic Data

open access: yesISPRS International Journal of Geo-Information, 2020
To equally distribute the workload and minimize the travel distance for fire departments, we developed a new dynamic floating stations model (DFSM) to target traffic-related emergency medical services (EMS) during peak hours.

A Meta-Optimization Approach to Solve the Set Covering Problem

open access: yesIngeniería, 2018
Context: In the industry the resources are increasingly scarce. For this reason, we must make a good use of it. Being the optimization tools, a good alternative that it is necessary to bear in mind.

Set Covering with Our Eyes Closed [PDF]

open access: yesSIAM Journal on Computing, 2008
Given a universe U of n elements and a weighted collection l of m subsets of U, the universal set cover problem is to a-priori map each element u epsi U to a set S(u) epsi l containing u, so that X sube U is covered by S(X)=UuepsiXS(u). The aim is finding a mapping such that the cost of S(X) is as close as possible to the optimal set-cover cost for X. (

Knapsack with Vertex Cover, Set Cover, and Hitting Set

open access: yesCoRR
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 ...

Cluster-Based Control Information Exchange in Multi-Channel Ad Hoc Networks With Spectrum Heterogeneity

open access: yesIEEE Access, 2017
To overcome the constraint of spectrum heterogeneity, i.e., different spatial locations may have different available spectrum resources, nodes in a multi-channel ad hoc network (MCAHN) should exchange necessary control information.
