We may define a forest of stunted trees as follows: Consider an infinite background of nodes at the vertices of an infinite plane tessellation of equilateral triangles., and start from a straight line of nodes at unit distance apart, which we shall consider as the ground; other parallel lines of nodes are then spaced at successive levels of linearly increasing heights above the ground. Any node may be live (if a tree passes through it) or vacant otherwise. Any live node may give rise to a… Expand

This paper is a self-contained sequal to Miller (1970), entitled ‘Periodic forests of stunted trees’. It is concerned with ‘Copses’ and ‘Tessellations’ based on an infinite background of nodes at theExpand

Miller has observed that there are a finite number of periodic forests whose largest clearings are of size 1 or 2, and an infinite number whose largest clearings are of size 4. In this note the basicExpand

The number of distinct periodic forests whose largest clearings are of size n is known to be 1 (n = 1), 1 (n = 2), 12 (n = 3), and ∞ (n = 4). In this note it is shown that there exist an infinity ofExpand
Algebraic Dynamics of a One-Parameter Class of Maps over Z 2
Motivated by the Ducci Map and Wolfram’s Rule 90, this paper studies the relationship of the period lengths of the maps W (n, k) = In + T k n as a function of n and k, where In is the identity mapExpand
Characteristic and Minimal Polynomials of Linear Cellular Automata
The 1984 article by Martin, Odlyzko and Wolfram on Wolfram’s Rule 90 heightened interest in the area of linear cellular automata defined on a vector space over a finite field [8]. In this article weExpand
Shift-symmetric configurations in two-dimensional cellular automata: Irreversibility, insolvability, and enumeration.
TLDR
This work employs group-theoretic methods, which allow us to identify and enumerate these inputs, and argue about irreversible system behaviors with undesired effects on many computational problems, to better grasp and understand symmetry of configurations in decentralized toroidal architectures.

Algorithmic complexity, also called Kolmogorov complexity and Kolmogorov-Chaitin complexity, motivates the use of techniques to approximate the complexity of objects and measure similarity betweenExpand
