In a cellular automatona Garden of Eden is a configuration that has no predecessor. It can be the initial configuration of the automaton but cannot arise in any other way.

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. This is a preview of subscription content, log in via an institution.

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. Within this intricate tapestry, life and entropy engage in a mesmerizing choreography of creation and annihilation, giving rise to a dynamic universe of patterns, cycles, and emergent order that has captivated mathematicians, scientists, and enthusiasts alike for decades. This voyage commences with the stochastic selection of an initial configuration on a two-dimensional lattice adorned with cells. These embryonic cells, though devoid of consciousness, are subject to a tapestry of laws as previously elucidated.

In a very few cases, the society eventually dies out, with all living cells vanishing, though this may not happen for a great many generations. Tools Tools. The religious parallels are intentional. Conway's Game of Life and related cellular automata. Online ISBN : Bibcode : SciAm. Google implemented an easter egg of the Game of Life in In their earlier work, Moore and Myhill did not distinguish orphans from Gardens of Eden, and proved their results only in terms of orphans. A simple universal cellular automaton and its one-way and totalistic version. The initial pattern constitutes the seed of the system.

By definition, every orphan belongs to a Garden of Eden: extending an orphan to a configuration of the whole automaton, by choosing a state for each remaining cell arbitrarily, will always produce a Garden of Eden. The religious parallels are intentional. To appear Theoretical Computer Science, This is the first new spaceship movement pattern for an elementary spaceship found in forty-eight years. ISSN Minsky M. A configuration may have zero, one, or more predecessors, but it always has exactly one successor. However, the number of patterns that would need to be generated to find a Garden of Eden in this way is exponential in the area of the pattern. Smaller patterns were later found that also exhibit infinite growth. On May 18, , Andrew J. Google Scholar Serizawa T.
