dc:description "analysis.py evolves every elementary rule on a ring of 64 cells and every Moore totalistic code on a 16 by 16 torus for 32 steps, from three shuffles at each of two exact black counts. A rule switches when at least two replicates end below 0.15 from the low count and at or above 0.85 from the high count, averaging t = 25..32. A second run matched derived/measured.json byte for byte.";
<http://www.w3.org/2000/01/rdf-schema#comment> "Measured: 0.0029296875 fraction of the 1024 Moore totalistic rules that switch (n = 1024, exact on these grids, seeds and the 32-step horizon). Interpretation: A density-driven switch means the initially more common color takes over the lattice: a start with black fraction near 0.35 ends at or below 0.15, and a start near 0.65 ends at or above 0.85. 'Fairly rare' in one dimension is a switching fraction at most 0.05. 'Increasingly common' in two dimensions is a fraction at least twice the one-dimensional fraction and at least 0.02. The two-dimensional family is the 1024 totalistic Moore rules, not the full outer-totalistic space, and the grid is 16 by 16 so that the run stays small. Three dimensions are not tested. The computation says nothing about organisms.";
