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

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:

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

But to obtain a contiguous range, since we have the 56-bit cloverleaf interchange, we'd need to observe still-lifes of bit-counts {43, 47, 48, 49, 50, 51, 52, 53, 54, 55} before any 58-or-higher still-life occurs. That's highly implausible.

Half of your prediction is already off, with the appearance of a methuselah_43k in the G1 census:

http://gol.hatsya.co.uk/object/methuselah_43k/b3s23

44k and 45k have ("arguably naturally") occurred in C1 and 2x128, respectively.

As for a 43-bit still life, I am sure it will occur soon, before a still life < 56 bits appears.
(It may have appeared in a g1 soup already)

No, because there are still gaps at 45k and 46k. My prediction is that more gaps will be created (beyond 47k) before you manage to fill those.

45k is already seminatural (2x128 is not symmetric.)

As for 46k, I am very sure it would occur before <47k occurs.

Furthermore, I have reason to believe that cloverleaf interchange WILL be the highest bitted SL for several years to come unless some astounding SHA-256 hash comes. CI has not just D2_1 symmetry but D8_1 symmetry making it a high attractor (in terms of 100 trillion soups, anyhow) and there is plenty of time for 43 to at least 50 to fill.

... And oh, you meant contiguous as "appearing at the same time", not just "consecutive appearing range"? Ah...

Also, on this:

Macbi wrote:
calcyman wrote:Indeed. I wouldn't classify that as a methuselah unless the reaction managed to destroy the switch-engines (as was the case for the 750k methuselah from b38s23/C1).

I see that there's something different about this pattern compared to other methuselahs, but I don't see why destroying the switch-engines or not would be an important part of the requirements. Is it because you don't think that an infinite-growth pattern can be said to have stabilised? I would say that an infinite growth pattern can be considered stabilised so long as it is growing in a regular way. (The phrase "regular way" isn't precisely defined, but I think switch engines definitely satisfy it.)


This got me thinking - what if an unusual type of breeder can be made, such that some switch engines and junk together fire the correct gliders backwards to create the same junk and switch engines again?

Of course, this is highly improbable, but at least it may be possible for the backward-firing gliders to spawn one new switch engine.
