The Relationship between the Unicost Set Covering Problem and the Attribute Reduction Problem in Rough Set Theory

The unicost set covering problem and the attribute reduction problem are NP-complete problems. In this paper, the relationship between these two problems are discussed. Based on the transformability between attribute reductions and minimal solutions in unicost set covering models, two methods are pr...
