http://liinwww.ira.uka.de/ca/mfcs-98/

Extractions: The Aim Cellular Automata have attracted a lot of attention recently. Progress has been made in several areas and new topics have been brought up for further research. The aim of the workshop is to allow for an exchange of ideas, to highlight new approaches and results (as well as problems), and to present them to a broader audience in the MFCS CSL environment. Topics Suggested topics of interest include (but are not limited to): cellular automata as models of parallelism, computational complexity of cellular automata, cellular automata as dynamical systems, cellular automata as complex systems, cellular automata models for real phenomena (in physics, biology, etc.), algebraic properties of cellular automata, cellular automata machines, generalizations of cellular automata, modelling interactive behaviour with cellular automata.

The aim is here much more limited. This site being devoted to laymen, I will content myself with answering both main questions any person discovering cellular automata often ask, generally after a period of intense perplexity : What might this be ? What could be the applications for such a thing ? The answer to these questions is unfortunately far from being simple. cellular automata are abstract constructions with quite complex properties not very accessible. As a sideline, John von Neumann, relying on A. Turing's works, interested himself on the theory of self-reproductive automata and worked on the conception of a self-reproductive machine, the "kinematon". Such a machine was supposed to be able to reproduce any machine described in its programs, including a copy of itself . The most famous of his machines is the monolith of the series "

He actually put this in the game, even though it was an Apple 2 game. He kind of emulated what would later become the Mac interface. But it was very easy to use, and you would create pinball sets with it which you could then play with. I thought that was very cool.

Extractions: Main Generate Cellular Automata The Cellular Automaton The source code to my Cellular Automaton image generator can be found here . It is C++ source code that outputs a raw pgm image file to stdout. It should compile under most C++ compilers, although it has only been tested with the g++ compiler on Linux. I am releasing it under the GNU Public License (GPL), so do with it as is appropriate under that license. The cellular automaton consists of a line of cells, each colored either black or white. At every step there is then a definite rule that determines the color of a given cell from the color of that cell and its immediate left and right neighbors on the step before. -Stephen Wolfram (A New Kind of Science, 2002) Cellular automata are extreamly simple computational systems that create interesting images which show some even more interesting behaviours. Essentially, these images show the product of thousands of simple computations based on rules that should be followed regarding a pixel's imediate neighbours. These cellular automata images are a bunch of black and white pixels that are built from the top down, where each scanline is based on the colour of the pixels on the scanline above it. More specifically, the pixels imediately above it, above it and to the left, and above it and to the right. So each pixel's colour is determined by three other pixels.

Extractions: In the early 1950's, the well-known mathematician John Von Neumann was trying to develop what he termed a self-replicating automaton; that is, a machine whose computer brain was capable of devising instructions to effect the construction of itself. Von Neumann never actually intended for the machine to be built. Rather, he was interested in arriving at rules by which a computer could be programmed such that it could fashion an exact replica of itself. He envisioned initially a robot wandering around a warehouse littered with spare parts, identifying the relevant pieces, and fashioning an exact replica of itself. As the legend goes, Von Neumann fooled around with various approaches for a while but was not satisfied with the results. The physical movement of pieces by the robot did not seem to fit the mathematical theory he desired, nor did the complexity of various attempts at solution suit his liking. Von Neumann sought a solution that was simple, elegant, and general. Stanislaw Ulam, a fellow mathematician, suggested to Von Neumann a different approach. Consider a rectangular array of cells, much like a chessboard, in which each cell can exist in one of a finite number of states: 0, 1, 2, ... Time would progress discretely (i.e. in jumps, rather than continuously. Each increment of time would be a chance for cells to change their state. The rule governing the change of state for each cell would depend only upon the states of the cell's immediate neighbors and possibly upon the state of the cell itself. The rule would be the same for each cell and all cells would change (or not change) according to the rule with each time step. All cells would initially be in the 0, or quiescent, state; to start the automaton, place some cells in nonzero states and start the clock. Watch the cells and see how they changed according to their localbut commonrule. Ulam's grid was an example of a cellular automaton.

Extractions: CA gallery ... New CA Forum T his site is devoted to Cellular Automata, one of the most intriguing and admirable aspects of mathematics. Perhaps you have already heard about the Game of Life, one of oldest and best-explored Cellular Automata. Game of Life is only a tip of a large cellular iceberg. Actually, the count of even simple Cellular Automata is estimated to be *much* larger then the count of particles in our Universe! I decided to explore a bit of this huge world. To do it I developed my own Cellular Automata simulator, MCell, and with help from many people I collected a big library of Cellular Automata families, rules, and patterns. You can see much of my collection on these pages. Anyhow, the pages show only a static side of Cellular Automata. Cellular Automata are in fact very dynamic, so I strongly encourage you to download the free MCell software and/or run the MJCell Java applet to see the patterns running! And then, who knows, maybe you will also add something new to the Cellular Automata world?

Extractions: To go with this section I have created a mini version of conway's life. Click here to launch. The father of Cellular Automata , and aLife come to that, is John von Neumann. He was the first to propose a system for producing life like results from simple rules. His aim was self reproduction; a John von Neumann machine is one that can do this. A cellular automata is an array of 'cells' that interact with their neighbors. These arrays can take on any number of dimensions, starting from a one dimensional string of cells. Each cell has its own State that can be a variable, property or other information. By receiving input from connected cells or general messages a cell uses its own set of rules to determine what its reaction should be. This reaction is a change of state and can also be a trigger to send out its own messages. These messages are passed onto other selected cells which cause them to act like wise. Natural cells work much in the same way. For example in an embryo messages are spread by timed releases of chemicals by cells which tell a cell which type of cell it should be. Each cell has a look up library, the code of DNA, to control its actions. A cell also has a chemical plant and chemical responses that act as its input and output devices. These plants are controlled by RNA, the slaves of DNA. Different doses of chemicals and in different combinations cause a cell to act in different ways. Sometime small changes in chemical density can lead to radical changes in cell formation. This is how cell barriers are formed. By a mixture of co-operation and competition complex forms, like a human baby, can be built up.

We need to consider the seldom discussed moral, ethical, and religious questions raised by intelligent machines that will be able to think and feel, so we can make informed decisions about the kind of future we want to live in. The book is written for a general but scientifically curious audience, particularly those interested in mankinds future, machine intelligence, morality, ethics, cognitive science, science and society, science policy, religion, and the philosophy of science.
