The 'game' is a zero-player game, meaning that its evolution is determined by its initial state, requiring no further input. "Life: Nasty, Brutish, and Short" ( web). The Game of Life, also known simply as Life, is a cellular automaton devised by the British mathematician John Horton Conway in 1970. Reprinted SIGPLAN Notices Volume 7, Issue 4 in Algorithms.

John Scholes' notes, as part of the dfns workspace, includes a more in-depth treatment.It finds adjacent elements by rotating the original array, causing elements at the edge to wrap around (giving a torus geometry). The implementation takes advantage of nested arrays and the Outer Product to produce many copies of the argument array. More recently, it is sometimes seen as a use case for the Stencil operator, which provides a concise way to work on three-by-three neighborhoods as used by the Game of Life.Ī famous video by John Scholes explains the following Dyalog APL implementation step by step. APL implementations have appeared in the APL Quote-Quad since 1971, a year after the rules of the Game of Life were first published. Because it involves interactions between adjacent elements of the matrix, and can take advantage of APL's convenient and fast Boolean handling, implementing the Game of Life is a popular activity for APLers. The Game of Life is defined on an infinite Boolean grid, but usually only finite patterns, where all 1 values fit in a finite Boolean matrix, are studied. Conway's Game of Life is a well-known cellular automaton in which each generation of a population "evolves" from the previous one according to a set of predefined rules.
