A 32x32 50% soup in B36/S23 (HighLife) typically stabilizes in about 1000 generations.
A similar soup in B38/S23 also typically stabilizes in 1000 generations or so, though not uncommonly it persists a few thousand generations.
A similar soup in B37/S23 (DryLife) almost always explodes.
Question: Why? Why, when B36/S23 and B38/S23 are stable, is B37/S23 explosive?

Presumably it's not solely the frequency that matters, but the consequences when they do occur.BlinkerSpawn wrote:Presumably because preloaves occur more often than pies.Rich Holmes wrote:In fact B37c/S23 is explosive, while B37e/S23 isn't. I have no idea why.
If you consider an isolated preloaf and pi in each of the two rules...
Code: Select all
x = 31, y = 12, rule = B37c/S23 5$6b2o16b3o$5bobo18bo$5b3o16b3o!

But patterns containing non-isolated preloaves and pis need to be considered too.

An isolated B-heptomino in B37e/S23 is much more chaotic than that in B37c/S23, but after adding a still life, it turned out to be the opposite.
B+SL reactions are far less chaotic in B37e/S23, while the same reactions are often catastrophic in B37c/S23.
Such self-sustaining behavior may be the key to explain why B37c/S23 allows chaotic dynamics to appear in the center of a soup, while B37e/S23 only allow chaotic dynamics to appear on the edge of a soup.Rich Holmes wrote: the pi takes more time and more space to stabilize in B37c/S23 than in B37e/S23 while the preloaf in B37e/S23 does not get that large nor take that long to settle.
