alife_life_step — 2D `artificial-life` op

• Data kinds: image → image

• Call: fullseye.apply(img, "alife_life_step", 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

Life-like totalistic cellular automaton (Conway-family B/S rules).

The image is thresholded at 0.5 to obtain the initial live/dead lattice, then

a totalistic outer-neighbourhood rule is applied on the torus: a dead cell is

born when its live Moore-neighbour count lies in the birth set B, a live cell

survives when its count lies in the survival set S. `a` picks the rule

preset -- Conway B3/S23, HighLife B36/S23, Day&Night B3678/S34678, Seeds B2/S

-- and `b` sets the generation count 1 + int(9b). Returns the live-cell

field as 0.0/1.0.
