alife_wolfram1d — 2D `artificial-life` op

• Data kinds: image → image

• Call: fullseye.apply(img, "alife_wolfram1d", a=0.5, b=0.5) (the 2-D model is one image plus two scalar knobs a,b∈[0,1])

*The figure is the real output on a synthetic 128×128 input. Left: input, right: output (a non-image return value is shown as the value itself).*

Usage

Wolfram elementary 1-D cellular automaton, drawn as a spacetime diagram.

Reimplements the elementary (radius-1, two-state) cellular automata of

S. Wolfram, Rev. Mod. Phys. 55, 601 (1983) / *A New Kind of Science* (2002).

The initial row is the top row of the image thresholded at 0.5; if that row

is empty a single central seed is used instead, which is the classical

initial condition (rule 90 from a single seed is Pascal's triangle mod 2,

i.e. the Sierpinski gasket). The lattice is circular, one generation is

written per output row, and row 0 is generation 0, so the output is the H x W

{0,1} spacetime diagram.

`a picks the rule from the curated table _ELEMENTARY_RULES`;

`b sets the initial density by adding int(b * W/2)` evenly spaced extra

seed cells to row 0 (b = 0 leaves the thresholded row untouched).
