Sorry, can anyone explain the difference between C1 and G1?

G1 only saves soups with interesting stuff.

G1 only saves soups with interesting stuff.

So that would increase the search speed?

Please, post in the right thread. There's no need to ping everyone who's subscribed to this one, on the assumption that the only new posts will be for interesting new objects. Basic questions don't belong here.

Ditto what Apple Bottom said, but to give a more specific answer, the G1 search uses a GPU to increase the speed of the search. The GPU runs soups but does not census them on its own; instead, it looks for soups meeting one of the following criteria:
  • The population does not become periodic with period 6 within 12,000 generations.
  • The pattern, excluding escaping spaceships, escapes the boundaries of the finite universe it's simulated in.
These soups are then simulated by the CPU afterwards to get a full census since they're considered "interesting." This means that the GPU considers high-period oscillators/spaceships, methuselahs, and megasized soups interesting, but ignores still lifes, low-period oscillators, and diehards.

Sorry for the profound necropost, but to just comment on this:

(so much for the 42K is the answer to life)


Interestingly, 42 now has a double special significance in Catagolue:

  • The last time there was a contiguous range of still-life bit counts was {..., 40, 41, 42};
  • The last time there was a contiguous range of methuselah bins was {..., 40, 41, 42};

and, with high probability, that will remain the case forever.


There's a strong bias on even-bitted still lives, anyways, as a common way they form (i.e. cloverleaf) is by the soup attaining some form of symmetry. Look in any census with symmetry (excl. 2x128, 4x64 and 8x32), and you'll see that the last few rows in the "still life" column are dominated (90% ~ 100%) by even-bitted still lives.

Furthermore, "forever" is quite a long time; this (the most common xs43 in D8_1) seems bound to occur soon, given that C1 has 20x the amount of soups as D8_1:

Code: Select all
x = 11, y = 12, rule = B3/S23

When alphabet soup searching (soup searching with words), I arguably found the fourth occurrence of cis-boat-with-tail-siamese-long-boat-with-tail (xs17_xggka53z6a43):

x = 39, y = 5, rule = B3/S23

A weird object forms at T=1139.
