Converse game of life

In a cellular automatona Garden of Eden is a configuration that has no predecessor.

The Game of Life was created by J. One of the main features of this game is its universality. We prove in this paper this universality with respect to several computational models: boolean circuits, Turing machines, and two-dimensional cellular automata. We also present precise definitions of these 3 universality properties and explain the relations between them. These keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.

The Game of Life , also known simply as Life , is a cellular automaton devised by the British mathematician John Horton Conway in 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. The universe of the Game of Life is an infinite, two-dimensional orthogonal grid of square cells , each of which is in one of two possible states, live or dead or populated and unpopulated , respectively. Every cell interacts with its eight neighbors , which are the cells that are horizontally, vertically, or diagonally adjacent. At each step in time, the following transitions occur:. The initial pattern constitutes the seed of the system. The first generation is created by applying the above rules simultaneously to every cell in the seed, live or dead; births and deaths occur simultaneously, and the discrete moment at which this happens is sometimes called a tick. The rules continue to be applied repeatedly to create further generations. Stanislaw Ulam , while working at the Los Alamos National Laboratory in the s, studied the growth of crystals, using a simple lattice network as his model. This design is known as the kinematic model. Neumann wrote a paper entitled "The general and logical theory of automata" for the Hixon Symposium in The driving concept of the method was to consider a liquid as a group of discrete units and calculate the motion of each based on its neighbors' behaviors.

Through this journey, we aim to unveil the profound beauty and insights that this seemingly simple cellular automaton bestows upon the fields of mathematics and science. Conceived in the midst of the 20th century, this intricate game unveils a cosmos governed by rules that can be succinctly articulated as follows:. Solitude and Isolation: When a living cell finds itself surrounded by fewer than two living neighbors, it languishes into the void, succumbing to the stark isolation that prevails. Resilience and Community: When a living cell discovers itself in the midst of two or three living neighbors, it perseveres, serving as an exemplar of resiliency in the face of adversity. Overpopulation and Crowded Demise: When a living cell bears witness to the tumultuous crowd of more than three living neighbors, it succumbs to the scourge of overpopulation, becoming a victim of its own popularity, ultimately perishing in the ensuing chaos. Rebirth and Revival: When the embrace of death shrouds a cell, awaiting the moment of rejuvenation, the spark of life is rekindled, ignited by the precise presence of three living neighbors. These seemingly simplistic tenets, deceptively elementary on the surface, coalesce to create a system of staggering complexity.

Cellular automata on a two-dimensional grid that can be described in this way are known as Life-like cellular automata. Read Edit View history. Retrieved February 18, One-dimensional square variations, known as elementary cellular automata , [60] and three-dimensional square variations have been developed, as have two-dimensional hexagonal and triangular variations. With the advent of microcomputers and Cromemco's graphics board, Life became a favorite display program for video monitors and led to a revival of interest in the game. Still lifes Block. Moore neighborhood Speed of light Von Neumann neighborhood. One interacts with the Game of Life by creating an initial configuration and observing how it evolves. This was tedious and prone to errors. Guy and S. Wade announced the first oblique spaceship, dubbed "Gemini", that creates a copy of itself on 5,1 further while destroying its parent.

Archived from the original on Mathematical System Theory , Vol. New York: Penguin Books. Neumann wrote a paper entitled "The general and logical theory of automata" for the Hixon Symposium in The result was a universal copier and constructor working within a cellular automaton with a small neighborhood only those cells that touch are neighbors; for von Neumann's cellular automata, only orthogonal cells , and with 29 states per cell. It can be the initial configuration of the automaton but cannot arise in any other way. These are rules that use the same square grid as the Life-like rules and the same eight-cell neighborhood, and are likewise invariant under rotation and reflection. For instance, a five-by-five block of dead cells and a five-by-five block with its center cell live and the remaining cells dead are twins: the state of the center cell cannot affect later configurations of the pattern. This design is known as the tessellation model, and is called a von Neumann universal constructor. Article Talk. When a new cell is born from three different on neighbors, it takes the fourth value, and otherwise, like Immigration, it takes the majority value.
