For example, the macroscopic structures of Life are Life are of great interest to the fields of Artificial Life and Theoretically possible to implement von Neumann's complicated self-Įven if the Game of Life is not a medium in whichĪctual life can be formed, the phenomena one can examine through Machine, tells us that ".it can be shown explicitly that it is This suggests that Life may also be able to perform theįunction of self-replication required of an actual living creature.Ĭlaus Emmeche, in his survey of Artificial Life, The Garden in the To begin with, Conway has shown that Lifeįorms such as glider guns can be used to create logic gates, theįoundations of a Universal Turing Machine. The Game of Life, Artificial Life, and PhilosophyĬonway's unique universe has many implications for the new If you experiment with different survival, death and birth, rules Using these criteria, he arrived at the rules ![]() Rules that allowed for patterns which grow and change for some timeīefore stabilizing. He did not desire a set of rules that led either to chaotic, Seem somewhat arbitrary, they were not arrived at by chance.Ĭonway had a specific set of criteria which governed his search for One other particularly interestingįorms are the spaceship, a structure similar to a glider that travelĪlthough the rules that Conway arrived at for Life may intially Other, more comlex forms, which cannot be dealt withĬomprehensively in this context. Life contains an amazing variety of still-lifes, blinkers and Below is a picture of the glider gun in action. Both were discovered by Bill Gosper of the Massachusetts Travels endlessly in a horizontal direction, leaving a trail of smokeīehind it. Glider gun simply continues to produce gliders, while the puffer train Produce populations of live cells that grow without limit. Glider guns and puffer trains are two unique Life forms that Requiring over 5000 generations to reach periodicity. The acorn is perhaps the longest lived methuselah known, Takes 1103 generations before it reaches a stable (periodic) state. Perhaps most famous methuselah is the R-pentomino which Methuselahs are initial patterns of live cells that require a large The eater is a still-life that is remarkable for it's capacity toĭevour gliders, provided that the glider approaches it at a certain If a glider is capable of escaping the milieu of a changing pattern, it One that travels a single diagonal cell ever four generations. However, it is not a stationary blinker, but The traffic light is a quite common form ofīlinker that has a period of two. Blinkers are periodic Life forms which have predictableīehavior. Theīlock and the beehive are two common forms of Over successive generations unless disturbed by other live cells. Still-lifes are stable forms that do not change Simple Life forms can generally be grouped into two categories: We will discuss the types of Life forms below. Various Life forms, composed of several or more living cells, often Live cells, the results can be startling. When one employs these rules to any given initial pattern of
