Abstract

Let A be a finite set, and let a symmetric binary relation be given on A. The goal of correlation clustering is to find a partition of A, with minimal conflicts with respect to the relation given. In this paper we investigate correlation clustering of subsets of the positive integers, based upon a relation defined by the help of the greatest common divisor.
