Abstract:
We consider a strongly NP-hard problem of partitioning a finite sequence of points in Euclidean space into two clusters minimizing the sum over both clusters of intra-cluster sum of squared distances from the clusters elements to their centers. The sizes of the clusters are fixed. The centroid of the first cluster is defined as the mean value of all vectors in the cluster, and the center of the second one is given in advance and
is equal to 0. Additionally, the partition must satisfy the restriction that for all vectors in the first cluster the difference between the indices of two consequent points from this cluster is bounded from below and above by
some given constants. We present a fully polynomial-time approximation scheme for the case of fixed space dimension. Bibliogr. 27.
