Polyomino Packing Models and Their Solutions for Engineering Layout Problems

open access: yes, 2010
application/pdfIn this paper, the authors discuss optimization algorithms for engineering layout problems in industry, such as sheet metal design, VLSI floor plan design and so forth. We propose game-theoretic algorithms by constructing polyomino packing

Counting Polyominoes, Revisited

open access: yes
Abstract A polyomino is an edge-connected set of squares on the square lattice. In this paper, we improve Jensen's algorithm for counting polyominoes by considering bounding boxes on the square lattice rotated by 45o instead of on the regular unrotated lattice. This allows us to extend significantly the count of polyominoes from 56 to 70 terms.

Word-representability of triangulations of rectangular polyomino with a single domino tile [PDF]

open access: yes, 2015
A graph G = (V,E) is word-representable if there exists a word w over the alphabet V such that letters x and y alternate in w if and only if (x,y) is an edge in E . A recent elegant result of Akrobotu et al.

Universal computation with arbitrary polyomino tiles in non-cooperative self-assembly

open access: yes, 2015
In this paper we explore the power of geometry to overcome the limitations of non-cooperative self-assembly. We define a generalization of the abstract Tile Assembly Model (aTAM), such that a tile system consists of a collection of polyomino tiles, the ...

Rectangular polyomino set weak (1, 2)-achievement games

open access: yes, 2008
In a polyomino set (1, 2)-achievement game the maker and the breaker alternately mark one and two previously unmarked cells respectively. The maker’s goal is to mark a set of cells congruent to one of a given set of polyominoes.
