  Also with capital initials. A particular form of cellular automaton based on a two-dimensional rectilinear array of cells, with two possible states for each cell and a very simple set of rules determining the behaviour of the cells.

  With the two cell states treated as ‘live’ and ‘dead’ the game can be regarded as modelling changes in a population, hence the name. It can generate a wide variety of interacting, self-reproducing patterns, and has been the subject of numerous computer graphic simulations.
