Effect of asynchronous updating on the stability of cellular automata

The surprising patterns in the aforementioned classroom example were generated by boxes in a line with just two states and a simple rule.One may wonder how many variations are possible on such a basic framework.The evolution of the system is determined by a transition rule, to be thought of as implemented in each cell.At each time step, each cell updates its status in response to what happens to its neighboring cells, following the rule.Secondly, CA are systems: they can compute functions and solve algorithmic problems.Despite functioning in a different way from traditional, Turing machine-like devices, CA with suitable rules can emulate a universal Turing machine (see entry), and therefore compute, given Turing’s thesis (see entry on Church-Turing thesis), anything computable.The mark of CA is in their displaying complex emergent behavior, starting from simple atoms following simple local rules.Because of this, CA attract a growing number of researchers from the cognitive and natural sciences willing to study pattern formation and complexity in a pure, abstract setting.

Section 2.1 provides a fourfold schematic definition of CA.But my discoveries in this book [ These are very bold claims.In order to assess them, let us take a closer look at the field.Let us make the two following assumptions: : a student will wear the hat in the following class if one or the other—but not both—of the two classmates sitting immediately on her left and on her right has the hat in the current class (if nobody wears a hat, a hat is out of fashion; but if both neighbors wear it, a hat is now too popular to be trendy). The global, emergent behavior of the system supervenes upon its local, simple features, at least in the following sense: the scale at which the decision to wear the hat is made (immediate neighbors) is not the scale at which the interesting patterns become manifest.This example is a paradigmatic illustration of what makes CA appealing to a vast range of researchers: and the micro-macro interplay have such an important role in science and philosophy (see the entries on supervenience and emergent properties; for a sample of scientific applications, see Mitchell 2009: 2–13; Gell-Mann 1994: Ch.
