( Game Of Life:
|
|
Any live cell with fewer than two live neighbours dies, as if by underpopulation.
|
|
Any live cell with two or three live neighbours lives on to the next generation.
|
|
Any live cell with more than three live neighbours dies, as if by overpopulation.
|
|
Any dead cell with exactly three live neighbours becomes a live cell, as if by reproduction. )
