Abstract. The work is devoted to the clustering algorithm FRiS-Cluster, the weak point of which is the parameter r*. This parameter must be specified manually, thus the correctness of choice can be judged only at the end of the algorithm. The article explores the dependence of the quality of clustering task solution on the value of r*. The heuristics for determining the obviously poor quality of clustering before the end of the algorithm working is formulated. On the basis of the derived heuristics an algorithm for automatic selecting the parameter r* is proposed.
