Grammar-Based Evolution of Polyominoes

open access: yes
Languages that describe two-dimensional (2-D) structures have emerged as powerful tools in various fields, encompassing pattern recognition and image processing, as well as modeling physical and chemical phenomena. One kind of two-dimensional structures is given by labeled polyominoes, i.e., geometric shapes composed of connected unit squares ...

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.
