Extended Generations rules are a generalization of Generations rules. This extension explores the result of changing the amounts of time cells can be active/inactive for, and also of allowing cells to "come back" from inactivity and alternate between being active/inactive an indefinite amount of times before dying.
They were conceived by users DigitalCross and later Milo Jacquet.[1]
Description
Extended Generations rules are described by rulestrings in the form Bb/Ss/Dd; where b and s are numbers between 0 - 8. The last segment, d, specifies ranges of activity/inactivity, starting with the former and then alternating.
We write n ∈ B, n ∈ S if n is one of the numbers in b, s; patterns then evolve according to the following rules:
- An active cell
- Remain in its current state if n ∈ S
- If not, it advances to state ((x + 1) mod y) in the next generation of the pattern where x is the current state and y is the total number of states.
- An inactive cell
- Advances to state ((x + 1) mod y) in the next generation of the pattern where x is the current state and y is the total number of states. I behaves like a normal Generations dying cell.
- A dead cell
- Advances to state 1 if n ∈ B.
- If not, it remains dead.
Generations and snoitareneG[2][3][4] can be considered subsets of the Extended Generations rulespace.[1]
Software support
Extended Generations rules are not natively supported by either Golly or LifeViewer, but can be run using the Golly's RuleLoader algorithm and a suitable rule table. Catagolue and apgsearch also support Extended Generations rules.
