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

- 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.

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

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:

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.calcyman wrote:Interestingly, 42 now has a double special significance in Catagolue:testitemqlstudop wrote:wow, congratulations!

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

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.testitemqlstudop wrote: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.

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

Posted: **July 22nd, 2019, 5:07 am**

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:

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

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?Macbi wrote: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.)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).

FWIW, my hunch is that all the patterns in the category that one exemplifies will eventually become "boring", either by lapsing into some kind of "predictability without actually having to keep running it" (there must be some way to formalize that concept!) while the arks (switch-engine pairs) continue interacting, or by one of those arks being destroyed. This is because as long as they remain un-boring, these patterns are liable to generate *WSSs that cross in front of an ark, as well as gliders that run parallel and close to them. Sooner or later, there will be a collision that blocks a switch-engine path in a destructive way.dvgrn wrote: ↑May 14th, 2019, 10:08 am

However, it's definitely true that infinite-growth patterns haven't traditionally been included in the "methuselah" category. Otherwise there are all kinds of difficult cases that would have to be considered, especially from Nick Gotts' old "Patterns with Eventful Histories" blog, from back in the days when weblogs were so new that not many people knew how to use them yet.

I'm not sure if anyone has figured out yet whether this 32-bit pattern ever goes boring, for example:

I think I'd vote against adding the new two-switch-engine soup to the methuselah list, to avoid opening yet another can of methuselah-worms.Code: Select all

Sometime, I must go back to that old "blog" and reformat it, and maybe resume investigation of the categories of pattern investigated there - but it could be some while...

Posted: **November 8th, 2019, 9:07 am**

Unfortunately, there are some metrics that apply to methuselahs (e.g. TTS=time to stabilize, EF=evolutionary factor=TTS/initial population, etc.) that rely on a precise point at which "stabilization" is reached; I guess that in patterns like this one, that would be the time at which "boredom" is achieved, which may be difficult to define objectively, let alone measure accurately.

Posted: **December 24th, 2019, 12:24 am**

The "time to boredom" is the time when e.g. for the D8_4 puffer methuselae when the glider streams form something like a boat-bit that stops them from interacting with the rest of the ash; dvgrn has measured this for numerous of the D8_4 methuselae soups. For Gotts' puffer methuselae it'd be more difficult to define, but it could be e.g. the time when an ark is destroyed or a glider eater is formed.
