Research output: Contribution to journalArticlepeer-review


We consider the problem of partitioning a finite set of Euclidean points into two clusters minimizing the sum over both clusters the weighted sums of the squared intracluster distances from the elements of the clusters to their centers. The center of one of the clusters is unknown and determined as the average value over all points in the cluster, while the center of the other cluster is the origin. The weight factors for both intracluster sums are the cardinalities of the corresponding clusters. In this work, we present a short survey on the results for this problem and a new result: a 2-approximation algorithm.
