An Ant Colony based Hyper-Heuristic Approach for the Set Covering Problem

open access: yesAdvances in Distributed Computing and Artificial Intelligence Journal, 2015
The Set Covering Problem (SCP) is a NP-hard combinatorial optimization problem that is challenging for meta-heuristic algorithms. In the optimization literature, several approaches using meta-heuristics have been developed to tackle the SCP and the ...

A tree search approach for the solution of set problems using alternative relaxations [PDF]

open access: yes, 1988
A number of alternative relaxations for the family of set problems (FSP) in general and set covering problems (SCP) in particular are introduced and discussed.

The set covering machine

open access: yes, 2002
Summary: We extend the classical algorithms of Valiant and Haussler for learning compact conjunctions and disjunctions of Boolean attributes to allow features that are constructed from the data and to allow a trade-off between accuracy and complexity. The result is a general-purpose learning machine, suitable for practical learning tasks, that we call ...

Attribute Reduction Based on Consistent Covering Rough Set and Its Application

open access: yesComplexity, 2017
As an important processing step for rough set theory, attribute reduction aims at eliminating data redundancy and drawing useful information. Covering rough set, as a generalization of classical rough set theory, has attracted wide attention on both ...

A set-covering formulation for a drayage problem with single and double container loads

open access: yesJournal of Industrial Engineering International, 2018
This paper addresses a drayage problem, which is motivated by the case study of a real carrier. Its trucks carry one or two containers from a port to importers and from exporters to the port.

A Variable Precision Covering-Based Rough Set Model Based on Functions

open access: yesThe Scientific World Journal, 2014
Classical rough set theory is a technique of granular computing for handling the uncertainty, vagueness, and granularity in information systems. Covering-based rough sets are proposed to generalize this theory for dealing with covering data.
