The paper presents a cursory examination of clustering, fo-cusing on a rarely explored field of hierarchy of clusters. Based on this, a short discussion of clustering quality measures is presented and the F-score measure is examined more deeply. As there are no attempts to assess the quality for hierarchies of clusters, three variants of the F-Score based index are presented: classic, hierarchi...

AI planning techniques are beginning to find use in a number of practical planning domains. However, the backward-chaining and partial-order-planning control strategies traditionally used in AI planning systems are not necessarily the best ones to use for practical planning problems. In this paper, we discuss some of the difficulties that can result from the use of backward chaining and partial...

We analyze the secular evolution of hierarchical triple systems to second-order in quadrupolar perturbation induced on inner binary by distant third body. The Newtonian three-body equations motion, expanded powers ratio semimajor axes $a/A$, become a pair effective one-body Keplerian perturbed sequence multipolar perturbations, denoted quadrupole, $O[(a/A)^3]$, octupole, $O[(a/A)^4]$, and so on...
