perpetual_elementary_ca — GENERATIVE perpetual op

• Data kinds: none → rgb (an op determined by its arguments alone — it takes no image or data input)

• Call: import fullseye as fs; fs.ledger.perpetual_elementary_ca(rule: 'int' = 90, width: 'int' = 401, rows: 'int' = 200, seed: 'int' = -1, cell: 'int' = 2) -> 'np.ndarray' (to call the implementation directly, import perpetual; perpetual.perpetual_elementary_ca(rule: 'int' = 90, width: 'int' = 401, rows: 'int' = 200, seed: 'int' = -1, cell: 'int' = 2) -> 'np.ndarray'; from the registry, opsgenerative.get("perpetual_elementary_ca"))

Usage

> This operator's description has not been translated yet. The original text follows as it is.

基本セルオートマトン(Wolfram の 256 規則)を上から下へ無限に伸ばす。

`seed < 0` で中央 1 点から始める(規則 90 ならシェルピンスキー、

規則 30 なら擬似乱数、規則 110 なら万能計算)。

不変量(規則 90・1 点始動): 第 n 行の第 k セルは C(n,k) mod 2。
