Application of ant colony optimization metaheuristic on set covering problems
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.

Covering Arrays via Set Covers
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.

The solvability of groups with nilpotent minimal coverings [PDF]
A covering of a group is a finite set of proper subgroups whose union is the whole group. A covering is minimal if there is no covering of smaller cardinality, and it is nilpotent if all its members are nilpotent subgroups. We complete a proof that every

Matrix Approaches for Covering-Based Multigranulation Fuzzy Rough Set Models
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 ...

On Asymmetric Coverings and Covering Numbers [PDF]
An asymmetric covering D(n,R) is a collection of special subsets S of an n-set such that every subset T of the n-set is contained in at least one special S with |S| - |T|

Minimal Covers and Arithmetical Sets [PDF]
If a a and b b are degrees of unsolvability, a a is called a minimal cover of b b if b > a b > a and no degree c c satisfies b > c > a b > c > a .

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

Covering t-sets with (t+2)-sets
Let \(X\) be a \(v\)-set of points and \({\mathcal B}\) be a family of \(k\)-subsets of \(X\), called blocks. Then the pair \((X,{\mathcal B})\) is called a \(t\)-\((v,k,\lambda)\) covering design if each \(t\)-subset of \(X\) is contained in (or is covered by) at least \(\lambda\) blocks. The minimum size of \({\mathcal B}\) is denoted by \(C_{\lambda}
