Create microbs population and look how it changes. Each cell has 8 near cells: 4 side and 4 corner. 1. If microb cell has less than 2 near microb cells - it dies. 2. If microb cell has more than 3 near microb cells - it dies. 3. If empty cell has exactly 3 near microb cells - it produces new microb cell. There are 3 basic formation types: 1. Stable - do not change.
