GROUP SO(4,2) AND SYMMETRY PROPERTIES OF D.I. MENDELEEV'S PERIODIC SYSTEM ELEMENTS
Доклады Белорусского государственного университета информатики и радиоэлектроники, 2019 The group-based method of classification of chemical elements for definition of their place in the Mendeleev’s periodic system of elements is considered.

Generating bicliques of a graph in lexicographic order
Theoretical Computer Science, 2005 A complete bipartite set \(B\) of a graph is a subset of vertices admitting a bipartition \(B=X\cup Y\) such that both \(X\) and \(Y\) are independent sets and all vertices of \(X\) are adjacent to those of \(Y\). If both \(X,Y\neq \emptyset\), then \(B\) is called proper. A biclique is a maximal proper complete bipartite set of a graph.

On Kotzig's Perfect Set Problem of Hamiltonian Cycle Decompositions of the Complete Graph
Journal of Combinatorial Designs, Volume 34, Issue 8, Page 388-409, August 2026.ABSTRACT A Hamiltonian cycle decomposition (HCD) of K n is a set of Hamiltonian cycles in which each 1‐path of K n appears exactly once. A Dudeney set of K n is a set of Hamiltonian cycles in which each 2‐path of K n appears exactly once. Kotzig's perfect set of HCDs of K n is a set of HCDs whose union forms a Dudeney set.

Simpler is better: a novel genetic algorithm to induce compact multi-label chain classifiers [PDF]
, 2015 Multi-label classification (MLC) is the task of assigning multiple class labels to an object based on the features that describe the object. One of the most effective MLC methods is known as Classifier Chains (CC).

The passion of butterflies: Notes on “translating” a Navajo poem by Rex Lee Jim
Journal of Linguistic Anthropology, Volume 36, Issue 2, August 2026.Abstract This essay honors three kinds of tradition. The first tradition is the poetry of Rex Lee Jim. The second tradition is the translation work of Blackhorse Mitchell. The third tradition is the discourse‐centered and ethnopoetic tradition of linguistic anthropology. I do this by focusing on a brief poem in Navajo by Rex Lee Jim.

ADAPTIVE REORDERING OF OBSERVATION SPACE TO IMPROVE PATTERN RECOGNITION
TASK Quarterly, 2007 The problem of observation space reordering is presented as a novel approach to pattern recognition based on non-parametric, combinatorial statistical tests. It consists in linearly ordering the elements of a discrete multi-dimensional observation space

Towards Characterization of Five‐List‐Colorability of Toroidal Graphs
Journal of Graph Theory, Volume 112, Issue 3, Page 267-275, July 2026.ABSTRACT Through computer‐assisted enumeration, we list minimal obstructions for 5‐choosability of graphs on the torus with the following additional property: There exists a cyclic system of non‐contractible triangles around the torus where the consecutive triangles are at distance at most four.
