George Maydwell's Cellular Automata Page Home of SARCASim (The Super Animation-Reduction Cellular Automata Simulator) The Glass CA on SARCASim I'm interested in fast programmable cellular automata. This is a hobby page devoted to SARCASim, first generation ARCA software for Windows. Collidoscope represents the next generation of ARCA, a quantum leap forward. It installs as a screen saver and runs large hexagonal CA simulations at roughly sixty generations per second. Collidoscope allows anyone to surf cellular automata rule space, even if they are not aware that they are surfing. One thousand six hundred and seventy three copies of Collidoscope were downloaded from ZDNet alone in a single day when they made Collidoscope their screen saver of the day. Check out ZDNet's Collidoscope review . Released in May 2001, Collidoscope 1.1 adds many new variations of Modern Hextenders. I've put up two more CA web sites! The Color Game Of Life Visual Exhibition is devoted to web based visual exploration of Conway's Game Of Life, in color. The Modern Cellular Automata site is devoted to web based visual exploration of color cellular automata rules which are not Conway's Game Of Life. Currently it demonstrates rule evolution starting from Brian's Brain.

Books Cellular Automata and Complexity: Collected Papers Cellular Automata and Complexity: Collected Papers by Stephen Wolfram Are mathematical equations the best way to model nature? For many years it had been assumed that they were. But in the early 1980s, Stephen Wolfram made the radical proposal that one should instead build models that are based directly on simple computer programs. Wolfram made a detailed study of a class of such models known as cellular automata, and discovered a remarkable fact: that even when the underlying rules are very simple, the behavior they produce can be highly complex, and can mimic many features of what we see in nature. And based on this result, Wolfram began a program to develop what has become A New Kind of Science The results of Wolfram's work found many applications, from the so-called Wolfram Classification central to fields such as artificial life, to new ideas about cryptography and fluid dynamics. This book is a collection of Wolfram's original papers on cellular automata and complexity. Some of these papers are widely known in the scientific community; others have never been published before. Together, the papers provide a highly readable account of what has become a major new field of science, with important implications for physics, biology, economics, computer science and many other areas.

In CA models of cardiac dynamics, the cells are either active, refractory or excitable. The length of time each cell spends in each state, as well as the size of the neighbourhood and the threshold for activation, are all adjustable parameters.

32. Gliders In "Life"-Like Cellular Automata An online interactive database of rules with gliders, by D. Eppstein.Category Computers Artificial Life Conway s Game of Life...... other definite class4 two-dimensional cellular automata were found in a random sampleof several thousand outer totalistic rules. Are gliders really so rare? http://www.ics.uci.edu/~eppstein/ca/

Which "Life"-Like Systems Have Gliders? John Conway's "Game of Life" has fascinated and inspired many enthusiasts, due to the emergence of complex behavior from a very simple system. One of the many interesting phenomena in life is the existence of "gliders": small patterns that move across the grid. Some authors have asserted that the gliders and other complex behaviors occurring in Life are unusual, for instance Wolfram: "Except for a few simple variants on the Game of Life, no other definite class-4 two-dimensional cellular automata were found in a random sample of several thousand outer totalistic rules." Are gliders really so rare? I have investigated whether gliders exist in many semitotalistic rules similar to Life, where the behavior of a cell depends only on its own state and the number of live neighbors. The results show that the existence of gliders is commonplace, contradicting Wolfram and calling into question his classification of cellular automata Jason Summers' c/5 diagonal spaceship in Life Online interactive database of rules with gliders Paper describing my glider search program and MSRI talk on streaming video Rules with self-replicating patterns New!

Notebooks Cellular Automata (Tue May 14 17:58:59 2002) The chess-board is the world; the pieces are the phenomena of the universe; the rules of the game are what we call the laws of Nature. -T. H. Huxley Take a board, and divide it up into squares, like a chess-board or checker-board. These are the cells. Each cell has one of a finite number of distinct colors - red and black, say, or (to be patriotic) red, white and blue. (We don't allow continuous shading, and every cell has just one color.) Now we come to the ``automaton'' part. Sitting somewhere to one side of the board is a clock, and every time the clock ticks the colors of the cells change. Each cell looks at the colors of the nearby cells, and its own color, and then applies a definite rule, the transition rule, specified in advance, to decide its color in the next clock-tick; and all the cells change at the same time. (The rule can say ``Stay the same.'') Each cell is a sort of very stupid computer - in the jargon, a finite-state automaton - and so the whole board is called a cellular automaton

Is a good description of many topics from cellular automata to artificial lifeCategory Computers Artificial Life cellular automata......15 January 1997 There are few topics in computer science that are as diverselyapplicable and as actively explored as cellular automata. http://www.go2net.com/internet/deep/1997/01/15/body.html

15 January 1997 There are few topics in computer science that are as diversely applicable and as actively explored as cellular automata. Much of the research going on in computer science today finds some basis in cellular automata or utilizes cellular automata in some fashion. It has turned up in artificial life, image processing, distributed computing, and encryption, to name a few. In fact, it doesn't stop at computer science; cellular automata have been used to model population growth, urban development, energy diffusion in a gas, decentralized goal-oriented behavior, and an enormous list of other things that I don't care to enumerate. Now that you're sufficiently intrigued by the topic, I'll proceed to give you just enough background on cellular automata to get yourself in trouble at parties . First, a definition suitably detailed to allow the article to make sense and suitably vague so as to annoy the mathematicians: A CA is characterized by a set of cells and a set of rules. The cells are commonly, but not necessarily (as we'll see later) organized into a two-dimensional grid extending infinitely in both directions. The cells have characteristics or states , generally something along the lines of on/off or a numerical value.
