Thread for Discord crossposts

[Hdjensofjfnen]

This is a general-purpose thread for humans or bots to crosspost important messages from the Conwaylife Lounge Discord, making them easier to be cited on LifeWiki or read by forum users.

Though this thread is intended to eliminate the barrier of finding the "right" thread to crosspost a Discord message in, please still post discoveries in their appropriate thread in the Patterns forum if applicable.

[Hdjensofjfnen]

here's a glider-powered block keeper, such that the block can be read:

this is one step up from that any-input-safe toggle, could probably have some use in logic gates

I was told (offline) that Discord has a proof of "pseudo-oscillators" being minimally-separable into more than 4 pieces (thus unlike pseudo still lives) that works by introducing intersection component (so connection graph is no longer planar)

I don't think it's in News Archive on wiki, nor on any pages (tho that I might have missed)

[confocaloid]

Can this claim be substantiated?

Sorry to be the bearer of bad news, but WFx71H is already known. (Found by ljkiernan and posted to Discord in 2023, somehow never made it to the forums)

(also, please make this thread pinned in the subforum)

I hate this with a passion

I'm drawing a blank on why LifeViewer is giving an "unsupported rule name" error, since the rule is definitely out there in the LifeWiki Rule namespace ... but given the GIF, maybe that doesn't really need to be sorted out.

The new version of safeopenclip.lua is able to find and load the rule into Golly with one click from the snazzy new HTML pop-up link page, and then the pattern works just as the GIF advertises.

I'm drawing a blank on why LifeViewer is giving an "unsupported rule name" error, since the rule is definitely out there in the LifeWiki Rule namespace

It's because there's an error in the rule definition. The following line ends with a ) rather than a }. That's 15 minutes of my life I'm not getting back...

Wow -- but somehow Golly managed to use that version of the rule without complaining.

I'm tempted to go look at Golly's parsing code and see how it manages that, but that would be a lot more than 15 minutes of my life that I wouldn't get back.

In for a penny...

Golly's parser gets the final token in the line as "6)" and then uses sscanf() with a %u format (unsigned integer) to decode. Fortunately (for Golly) when sscanf() decodes integers it ignores anything after digits so this successfully decodes as 6.

On a not entirely unrelated note I've just fixed the rule on LifeWiki.

[confocaloid]

Seems like it still doesn't work. Maybe the cause is missing commas in the actual rules? (e.g. "0 1,1,2,3,0,0,0,0 6")
Edit: it worked after doing hard refresh.

You'll need to hard refresh your browser.

unrelated, but here's an archive of all messages in the cgol channel, in json format - i've tried formatting it in some better format, to no avail [...]

[...] Meanwhile if you would really like to access the current progress without accessing the discord, you can download very's json file on the main cgol channel [...]

A request: could someone please share an updated archive of messages, in place of the old "cgol.zip" archive (which was later removed for unknown reasons)? Not everyone is able or willing to join a "walled" website just to be able to read.

(all results so far boxed, so you can go look in the queue if you want the unfiltered results)

DroneBetter — 10/04/2024 12:00 PM
@Exa how did you find these? surely not manually

Exa — 10/04/2024 12:01 PM
QuSrc (modded version of QuFince that does collisrc-y things at 25M colls/sec, currently not posted anywhere)
(I used to think it ran at 100M colls/sec but it turned out that I was incrementing the generation count by four each time it stepped by one so it was only running them for 50 steps each instead of the intended 200 😅 )

DroneBetter — 10/04/2024 12:02 PM
so do you input the set of things that you want it to synthesise and have it go through in random order?

Exa — 10/04/2024 12:03 PM
it's running an exhaustive search of the set of 5g collisions with glider placements in a 15x15 range, and checking whether any of them produce a still life known to shinjuku with a current cost of 6 or above

DroneBetter — 10/04/2024 12:03 PM
oh, I was under the impression that QuFince was directed rather than brute-force

Exa — 10/04/2024 12:03 PM
nah, one of the neat things is that it's an enumeration, so once you're done with a segment of the search space you're done
you may be thinking of Silk, by the same person and also a GPU-accelerated search program, which is directed.

DroneBetter — 10/04/2024 12:04 PM
is QuFince configurable for arbitrary INT rules and other spaceships in the place of the glider?

Exa — 10/04/2024 12:05 PM
QuFince original is mainly for catforce-y things and doesn't support the collisrc-y broad based "any relevant target" search
also it's cgol only by default

DroneBetter — 10/04/2024 12:07 PM
@apgoucher can you confirm or deny (is it written in lifelib or something bespoke for the particular finite grid sizes?)

Exa — 10/04/2024 12:09 PM
it is, in a very literal sense, written in lifelib
but the step function is very bespoke (also, now that I look at it, I'm actually using an old version locally that wasn't taking advantage of ternaries, I'll need to update)
https://gitlab.com/apgoucher/lifelib/-/ ... heads#L158
correction, it supports CGOL and pedestrian life

Exa — 10/04/2024 12:24 PM
Ooh, nice, 25% speedup from the new step function, up to 32M colls/sec
⁠cgol⁠
Since this is just about exactly the same speedup regular qufince got from this, that suggests that I'm entirely bottlenecked on advance (I still haven't profiled it properly, this is my first time picking it up since just before christmas last year)

Currently at 3.5 Tcolls out of a search space of 31.4 Tcolls
After I finish this run I'll put up the code - there's more I wanted to do with this before calling it good but I've already spent nine months doing nothing
nine days left if nothing interrupts it - if something does interrupt it I'll need to get around to implementing "resuming partially completed searches" which there's currently no way to do

#578730752464781312 apgoucher [Thu May 16 23:49:23 2019 UTC] I suppose, in theory, you could make one centipede produce all 62 glider streams at the back.

#578731014952583168 apgoucher [Thu May 16 23:50:26 2019 UTC] Orthogonoids are a thing.
#578731537743478815 apgoucher [Thu May 16 23:52:30 2019 UTC] And I think if someone makes an Orthogonoid with a spatial period of 16 (mod 32) and a temporal period of 0 (mod 4), then one Orthogonoid could drag that reaction behind it.
#578731783693139973 apgoucher [Thu May 16 23:53:29 2019 UTC] It would look like an isosceles right-angled triangle, where the Orthogonoid is the hypotenuse.
#578734186802970624 aforampere [Fri May 17 00:03:02 2019 UTC] <@!>, is there a nice way to send extra glider from it?
#578734785787068434 apgoucher [Fri May 17 00:05:25 2019 UTC] We can take Chris Cain's Orthogonoid and tighten it up to have a spatial period of 208 instead of 256:

#578735099332263946 apgoucher [Fri May 17 00:06:40 2019 UTC] !sim 1600 16
#578735569866326016 apgoucher [Fri May 17 00:08:32 2019 UTC] Then the left half emits 13 gliders per cycle (SE), the right half emits another 13 gliders (SW), and they interleave perfectly like a zip at the reaction site.
#578736216204247040 aforampere [Fri May 17 00:11:06 2019 UTC] What's your plan?
#578737817035735096 apgoucher [Fri May 17 00:17:28 2019 UTC] I realised in retrospect it wouldn't work as well as I wanted -- to somehow arrange some extra semi-Snarks attached to an output so that the Orthogonoid would produce the extra gliders at uniform intervals throughout the recipe (and then to pad out the recipe to ensure it's 13 * 2^N gliders in length).
#578737858261549058 apgoucher [Fri May 17 00:17:37 2019 UTC] Perhaps it's still somewhat salvageable.
#578738253914701828 aforampere [Fri May 17 00:19:12 2019 UTC] Every way seems really hard or really massive, or both
#578738672611098645 apgoucher [Fri May 17 00:20:51 2019 UTC] It's only slightly larger than a normal Orthogonoid, so I wouldn't say 'really massive'.
#578739068796665873 apgoucher [Fri May 17 00:22:26 2019 UTC] Also, Chris Cain's Orthogonoid won't work because it's restricted to have even glide symmetry.
#578739098735607818 apgoucher [Fri May 17 00:22:33 2019 UTC] We need odd glide symmetry.
#578739150031683594 apgoucher [Fri May 17 00:22:45 2019 UTC] Let me see whether Dave Greene's Orthogonoid496 suffices.
#578739410510807071 apgoucher [Fri May 17 00:23:47 2019 UTC] Ooh, excellent -- Orthogonoid496 works.
#578739712525860864 apgoucher [Fri May 17 00:24:59 2019 UTC] (But with the parameter 128 reduced to 120.)
#578740046006452260 aforampere [Fri May 17 00:26:19 2019 UTC] Would you only need 2 orthogonoids for this?
#578740170380148737 apgoucher [Fri May 17 00:26:49 2019 UTC] One Orthogonoid.
#578740542733680640 catisfluffy [Fri May 17 00:28:17 2019 UTC] How was that reaction discovered?
#578740593593942027 aforampere [Fri May 17 00:28:29 2019 UTC] Pure accident
#578740740113563669 aforampere [Fri May 17 00:29:04 2019 UTC] I was trying to do cleanup on a synthesis, and I saw the block and beehive shift.
#578740778101243905 aforampere [Fri May 17 00:29:13 2019 UTC] I thought it was weird, so I played with it for a bit
#578741372329132073 aforampere [Fri May 17 00:31:35 2019 UTC] 2c/25 seems to be the fastest it can go.
#578742002523570188 catisfluffy [Fri May 17 00:34:05 2019 UTC] K
#578776652579078155 dvgrn [Fri May 17 02:51:47 2019 UTC] That... is an impressively unlikely discovery. Fairly large automated searches have been run without turning up anything quite that good.
#578778857503588362 catisfluffy [Fri May 17 03:00:32 2019 UTC] How big would a Blockic eater be?
