Mirek's Java Cellebration v.1.51 what's new? Go back to MCell Home Mirek's Java Cellebration (MJCell) is a Java applet that allows playing 300+ Cellular Automata rules and 1400+ patterns. It can play rules from 13 CA rules families: Generations Life Vote Weighted Life ... Larger than Life , and some of the User DLLs . It allows also to experiment with own rules. The applet is a simplified version of MCell. It does not offer extended features of MCell, but has one advantage over it: its usage is not restricted to MS Windows. Full source code of the applet is available here . You can also download the full off-line version equipped with a rich library of patterns. You should also download this version if you plan to put the MJCell applet on your own Web page. To start the applet, click on the "Start" button below. The applet will show up in its own window.

106. Cellular Automaton cellular automata are the simplest models of spatially distributed processes . Some of the patterns produced, by several simple cellular automata, http://www.exploratorium.edu/complexity/CompLexicon/automaton.html

Cellular Automata (1947-present) Cellular automata are the simplest models of spatially distributed processes. They consist of an array of cells, each of which is allowed to be in one of a few states. At the same time, each cell looks to its neighbors to see what states they are in. Using this information each cell applies a simple rule to determine what state it should change to. This basic step is repeated over the whole array, again and again. Some of the patterns produced, by several simple cellular automata, are shown on this page. Cellular automata were invented in the 1940's by the mathematicians John von Neuman and Stanislaw Ulam, while they were working at the Los Alamos National Laboratory in northern central New Mexico. The most famous cellular automaton is the "Game Of Life" invented by mathematician John Conway, in the 1960's. Despite the simplicity of the rules governing the changes of state as the automaton moves from one generation to the next, the evolution of such a system is complex indeed. For interactive cellular automata simuations, go to Prof. David Griffeath's Java-based page

Home Digital Philosophy (DP) is a new way of thinking about the fundamental workings of processes in nature. DP is an atomic theory carried to a logical extreme where all quantities in nature are finite and discrete. This means that, theoretically, any quantity can be represented exactly by an integer. Further, DP implies that nature harbors no infinities, infinitesimals, continuities, or locally determined random variables. This paper explores Digital Philosophy by examining the consequences of these premises. At the most fundamental levels of physics, DP implies a totally discrete process called Digital Mechanics. Digital Mechanics[1] (DM) must be a substrate for Quantum Mechanics. Digital Philosophy makes sense with regard to any system if the following assumptions are true:

Acknowledgments and Further Information Introduction to CAMUS Since cellular automata produce large amounts of patterned data and if we assume that music composition can be thought of as being based on pattern propagation and formal manipulation of its parameters, it comes as no surprise that researchers started to suspect that cellular automata could be mapped into a music representation in order to generate compositional material. CAMUS is a cellular automata-based music generator. From many different cellular automata algorithms available today, two have been selected for CAMUS, namely Game of Life (invented by John Horton Conway) and Demon Cyclic Space (designed by David Griffeath). top Game of Life From one tick of the clock to the next, the cells of the Game of Life cellular automaton can be either alive (i.e., black) or dead (i.e., white), according to the following rules devised by Conway: if a cell is dead at time t , it comes alive at time

Wonders of Math Search What is the Game of Life? by Paul Callahan The Game of Life (or simply Life) is not a game in the conventional sense. There are no players, and no winning or losing. Once the "pieces" are placed in the starting position, the rules determine everything that happens later. Nevertheless, Life is full of surprises! In most cases, it is impossible to look at a starting position (or pattern ) and see what will happen in the future. The only way to find out is to follow the rules of the game. Play Life Now! [no button] Draw a pattern on the grid and click "Go". Applet help Applet by Alan Hensel Rules of the Game of Life Life is played on a grid of square cellslike a chess board but extending infinitely in every direction. A cell can be live or dead . A live cell is shown by putting a marker on its square. A dead cell is shown by leaving the square empty. Each cell in the grid has a neighborhood consisting of the eight cells in every direction including diagonals. To apply one step of the rules, we count the number of live neighbors for each cell. What happens next depends on this number.

What is Life and Cellular Automata? Go back to MCell Home What is Game Of Life How does it work? Game of Life history ... What are Cellular Automata good for? What is Game Of Life Conway's Life (Game Of Life, GOL) is the most well known cellular automaton. It has been extensively explored, and a large number of extraordinary patterns have been found. Perhaps to call it a game is somewhat misleading. It's not a game like Doom or other games you would play with a joystick. Life is more of a simulation where you can alter the parameters but you cannot actually alter the outcome directly; that is done by the conditions of the simulation. The game is played on a 2-dimensional grid. Each cell can be either "on" or "off". Each cell has eight neighbors, adjacent across the sides and corners of the square. The Life rule can be simply expressed (in terms of the way it affects a cell's behavior from one generation to the next) as follows: If a cell is off and has 3 living neighbors (out of 8), it will become alive in the next generation. If a cell is on and has 2 or 3 living neighbors, it survives; otherwise, it dies in the next generation.
