Are cellular automata useful?
Cellular automata (henceforth: CA) are discrete, abstract computational systems that have proved useful both as general models of complexity and as more specific representations of non-linear dynamics in a variety of scientific fields.
Is the game of life reversible?
Conway’s Game of Life, one of the most famous cellular automaton rules, is not reversible: for instance, it has many patterns that die out completely, so the configuration in which all cells are dead has many predecessors, and it also has Garden of Eden patterns with no predecessors.
Is the universe a cellular automaton?
Our universe is a Cellular Automaton consisting of a huge array of cells capable of storing numeric information. These cells form a vast, 3D ‘geometric’ CA, where each cell has 26 surrounding neighboring cells that influence the state of a given cell.
What you understand by cellular automata?
A cellular automaton is a collection of “colored” cells on a grid of specified shape that evolves through a number of discrete time steps according to a set of rules based on the states of neighboring cells. The rules are then applied iteratively for as many time steps as desired.
Who invented cellular automata?
John von Neumann
They were invented in the 1940s by American mathematicians John von Neumann and Stanislaw Ulam at Los Alamos National Laboratory.
What is a Totalistic cellular automata?
A totalistic cellular automaton is a cellular automata in which the rules depend only on the total (or equivalently, the average) of the values of the cells in a neighborhood. These automata were introduced by Wolfram in 1983. The best known two-dimensional totalistic cellular automaton is the game of life.
Is Conway’s Game of Life Turing complete?
It is a zero-player game, meaning that its evolution is determined by its initial state, requiring no further input. One interacts with the Game of Life by creating an initial configuration and observing how it evolves. It is Turing complete and can simulate a universal constructor or any other Turing machine.
Is Rule 30 reversible?
In fact, as mentioned in the previous article, the inverse of Rule 30 is “completely indeterminate” in the sense that no 3-bit pattern yields a unique antecedent for the central bit. If we consider global reversibility, especially in the context of a closed loop of cells, we find that Rule 30 actually is reversible.
Who discovered cellular automata?
They were invented in the 1940s by American mathematicians John von Neumann and Stanislaw Ulam at Los Alamos National Laboratory. Though apparently simple, some CAs are universal computers; that is, they can do any computer-capable computation.
