|
|
- time

Game-Of-Life Rules:
|
|
|
|
1.
|
|
Any live cell with fewer than two live neighbours
|
|
dies, as if caused by under-population.
|
|
2.
|
|
Any live cell with two or three live neighbours lives
|
|
on to the next generation.
|
|
3.
|
|
Any live cell with more than three live neighbours
|
|
dies, as if by over-population.
|
|
4.
|
|
Any dead cell with exactly three live neighbours be-
|
|
comes a live cell, as if by reproduction.
