Two-Player Tower of Hanoi [PDF]

open access: yes, 2017
The Tower of Hanoi game is a classical puzzle in recreational mathematics (Lucas 1883) which also has a strong record in pure mathematics. In a borderland between these two areas we find the characterization of the minimal number of moves, which is $2^n ...

The Estimating of the Number of Lattice Tilings of a Plane by a Given Area Centrosymmetrical Polyomino

open access: yesМоделирование и анализ информационных систем, 2015
We study a problem about the number of lattice plane tilings by the given area centrosymmetrical polyominoes. A polyomino is a connected plane geomatric figure formed by joiining a finite number of unit squares edge to edge.

A new multi-offspring crossover operator for genetic algorithm to facilitate the traveling salesman problem [PDF]

open access: yesComputer Science Journal of Moldova, 2019
This research work provides a detailed working principle and official analysis of a multi-offspring crossover operator. The proposed operator explains the true theory of survival-of-fittest using the foundation of evolutionary theories of biology and ...

Larger Corner-Free Sets from Better NOF Exactly-$N$ Protocols

open access: yesDiscrete Analysis, 2021
Larger corner-free sets from better NOF exactly-$N$ protocols, Discrete Analysis 2021:19, 9 pp. If $G$ is an Abelian group, then a _corner_ in $G^2$ is a subset of the form $\{(x,y),(x+d,y),(x,y+d)\}$ with $d\ne 0$.

Place-difference-value patterns: A generalization of generalized permutation and word patterns

open access: yes, 2009
Motivated by study of Mahonian statistics, in 2000, Babson and Steingrimsson introduced the notion of a "generalized permutation pattern" (GP) which generalizes the concept of "classical" permutation pattern introduced by Knuth in 1969.
