Pattern Of The Year 2022 Nominations

[Macbi]

It's time for POTY 2022!

Nominate patterns in this thread. All patterns nominated must be in B3/S23 and have been discovered in 2022. To ensure enough time for nominations I will declare the end of nominations no sooner that one week after the latest nomination. Voting will then take place in a separate thread.

I will summarise nominations in this LifeWiki page. Please use this thread to discuss these summaries.

[hotdogPi]

Ones that could actually win:

p34
p38
Unsynthesizable still life
Speed tunnel
Working RCT

[pzq_alex]

The five new p23 engines. (JP23, pi hassler, R hassler, 52P23, 92P23)

How about a general entry for new CatForce-based oscillators? Or could there be just one entry for the entirety of new oscillators?

[GUYTU6J]

• Engineered diehards
• Quartermax
• Gliderless breeder, the p48 puffer for Gosper glider guns
• 22, 21, 20-cell quadratic growth
• Self-synthesizing glide-reflecting loopship
• Speed orthogonoid
• Speed orthogonal loopship
• Nick Brown's strictly volatile oscillators
• Taco

A single entry for the entirety of oscillators and guns regardless of discovery/search method seems good enough to me.

[AlbertArmStain]

Something that isn’t mentioned yet is:

•new honeyfarm catalyst(s)

More specifically chucklebait

• …
• Speed orthogonoid
• Speed orthogonal loopship
  …

A single entry for the entirety of oscillators and guns regardless of discovery/search method seems good enough to me.

Speed orthogonoid and Speed orthogonal loopship can be combined to form the Omniship.

[Sokwe]

When posting a nominee, it would be extremely helpful if you include a link or links to the pattern or a description for the more complicated patterns. If possible, please also include a brief description (one or two sentences) and a list of discoverers for each nominee. Use last year's list as a template.

We will also need to determine in which cases patterns should be grouped into a single entry. For example, should the first p34 and p38 oscillators be kept separate or grouped into a single "new oscillator periods" entry?

[w33z8kqrqk8zzzw33]

Two more entries:

[*] Goldtiger997's component for adding a "crochet" to a c/3 spaceship
[*] small Max predecessors (many; see wiki page for links)

[Hdjensofjfnen]

I'd like to nominate Ilkka Törmä and Ville Salo's January discovery, first of a "self-forcing" stable agar that includes a portion of itself in each of its predecessors, then of a stable agar that includes a complete copy of itself in each of its predecessors, yielding solutions to the grandfather problem for arbitrarily large numbers of generations. Though this overlaps with the earlier nomination of the "unsynthesizable still life" that follows from the discovery, it's important to note the relationship to the formerly open extended grandfather problem as well.

Additionally, Törmä and Salo found a separate pattern that lacks a finite predecessor, but has an infinite one.

[toroidalet]

New spaceship syntheses (Goldtiger997, mniemiec, INoMed, Kazyan, pipsqueek, muzik)
Many syntheses were found for spaceships, including 10 distinct elementary spaceships and an infinite number of others based on the crotchet adder (another is almost complete). A few corderships, puffer-based ships and asymmetrical greyships were also synthesized as well.

[Sokwe]

New Reflector Periods
(by vivi, iNoMed, Matthias Merzenich, David Raucci, Mitchell Riley, MAP bot, Nico Brown, Tanner Jacobi, Noam Elkies)

90-degree reflectors for three new periods were discovered in 2022: a p23 dependent bouncer-based reflector, multiple p34 reflectors including the fastest possible bumper, and multiple p38 reflectors, including a bumper, a bouncer, and a duoplet-based reflector.

Working RCT
...

A Working RCT (by MathAndCode, calcyman, simeks, Dvgrn, AlbertArmStain, Pavgran, Macbi, chris_c, dani, and Goldtiger997)

A reverse caber-tosser (RCT) is a universal constructor that can build any synthesizable object in 15 gliders with a small bounded population, where a recipe is encoded in the distance between an approaching c/12 diagonal object (such as a Cordership or puffer) and the origin. One or more gliders shuttle between the Cordership and the fixed circuitry, causing the times between collisions to repeatedly halve. The pattern is named by analogy with the caber tosser which behaves as a time-reversed version thereof. Each iteration, the least significant bit of the recipe is consumed by the circuitry and typically routed to a universal construction arm.[1]

It was officially proven to be possible on November 9th, 2022 when Pavagran posted the fully completed RTC16 pattern along with it's semilator script and profiler report.

The pattern was built originally in 2018 by Adam P. Goucher and Dave Greene using a glider-pair reflection reaction found by Martin Grant in a whopping 329 gliders. MathAndCode, Pavgran, and dani eventually shrunk that all the way down to 15 gliders.

[hotdogPi]

The description needs to include that it's completed and not just a proof of existence as it was before 2022.

Don't worry, you can edit it if it's not what you like/expect

[pcallahan]

The discovery that surprised me most this year was the p24 glider gun: viewtopic.php?&p=151670#p151670

I prefer the original form using a Unix to the compacted 20x20 form. If you had told me that there was another compact gun composed of a few known parts, I wouldn't have believed without seeing it. Now I wonder if there are many others we've missed.

[dvgrn]

Just found out this morning that the Lisp in Life project got finished, way back in January. The last I had heard of it was here on the forums in December, but the README in the Git repo seems to have slightly different content from the blog post, especially toward the end. The blog post writeup is impressively thorough.

I'd like to nominate the Lisp in Life pattern for POTY 2022. It may have existed in some form in very late 2021, but it didn't get nominated then, and the blog post is from January 12, 2022.

[confocaloid]

I would like to nominate:

• Completion of the 21-bit strict still life synthesis project and completion of the 20-bit pseudo still life synthesis project, by multiple people
• Several new stable conduits and converters, including but not limited to a glider-releasing H-to-R by Mitchell Riley; a small stable 180-degree reflector by Simon Ekström (the "Jubjub reflector"); F149, Lx129, HL224H, RSE14T117, NW-2T16,
• The p8 glider reflector, a periodic 180-degree reflector that can be used as if it were stable

Suggested corrections to several list entries in the first post:

• "3. Unsynthable still life by Ilkka Törmä and kuluma" → "3. Unsynthesizable still life by Ilkka Törmä and Ville Salo"
• "13. Speed orthogonoid by authors" → "13. Speed Orthogonoid by authors"
• "14. Speed orthogonal loopship by authors" → "14. Speed Orthogonal Loopship by authors"
• "15. Nick Brown's strictly volatile oscillators" → "15. Nico Brown's strictly volatile oscillators"

[Ian07]

Suggestions:

• A collective entry for all the discoveries by Charity Engine and Open Science Grid, which vastly increased the number of soups being searched (see those articles for links to the individual discoveries). Credit to Darren Li for making both of these happen.
• Expand the 20-cell quadratic growth entry to include this 23x13 predecessor (the smallest known bounding box for quadratic growth) by dani, Luka Okanishi, and Rocknlol, as well as this 6G synthesis (cheapest known for quadratic growth) by dani.

[Macbi]

I've moved the summaries of nominations to this LifeWiki page so that other people can edit them. Please continue to use this thread for discussion.

Suggested corrections to several list entries in the first post:

• "3. Unsynthable still life by Ilkka Törmä and kuluma" → "3. Unsynthesizable still life by Ilkka Törmä and Ville Salo"
• "13. Speed orthogonoid by authors" → "13. Speed Orthogonoid by authors"
• "14. Speed orthogonal loopship by authors" → "14. Speed Orthogonal Loopship by authors"
• "15. Nick Brown's strictly volatile oscillators" → "15. Nico Brown's strictly volatile oscillators"

Last year used forum names for all authors, and I think this is a good policy since we know one for every nominee and we don't have to go asking for real names from contributors who are potentially children. I've made the other changes.

Done and done.

Last year used forum names for all authors, and I think this is a good policy since we know one for every nominee and we don't have to go asking for real names from contributors who are potentially children.

It's possible that some people want to be credited with a name other than their forum username. If so, they should mention that in this thread. Ultimately, like last year, I would want the credits to be converted to preferred names as per this table when transferring the nominees to the wiki Pattern of the Year page. In this regard we won't be restricted simply to forum user names.

It is also possible for people without forum user names to be nominated (e.g., with the Quest for Tetris Challenge). I don't know if any such person would have a pattern nominated this year.

[hotdogPi]

I just updated the wiki page (User:Macbi/POTY2022_Nominations) with:

• Link to RLEspace for p23 oscillators.

• List of discoverers for p23 oscillators.

• Description of p23 oscillators.

• Nico Brown's strictly volatile oscillators were obviously found by Nico Brown.

• Link to RLEspace for p24 glider gun.

• List of discoverers for p24 glider gun, although I don't know whether JP21 should be included or not.

Not changed, but could be: I feel like I wasn't the sole discoverer of Raucci's p38; it was a completion of a wick by Jason Summers.

Should the strictly volatile p86 be in the nomination list? It's not there yet.

I've made changes to the list to include links for

• Unsynthable still life
• Engineered diehard
• New spaceship syntheses
• Nico Brown's strictly volatile oscillators
• component for adding a "crotchet" to a c/3 spaceship (not a "crochet")
• American Dream

Figured I'd better post now to try to avoid any duplicate work, but I'm too late -- an edit conflict has showed up, so I'll have to figure out how to merge.

EDIT: Merged successfully, I think. The "Unsynthable still life" item has mutated into

"Unsynthable and limited-ancestor objects"

Question: would everybody be okay if I merge "American Dream" into the same group of limited-ancestor objects? I think it makes sense to mention the generalized great^N-grandfatherless patterns and the self-forcing p2 oscillator along with the unsynthable still life.

... Done editing the Wiki page for now -- somebody else's turn. Would advise posting intentions here before starting to edit. It's very easy to lose work when merge conflicts show up. I ended up having to make my edits three times, because MediaWiki's messages were somewhat contradictory, or at least very confusing.

Regarding the "CatForce oscillators" entry, is there any way to identify only the oscillators found with CatForce? Entity Valkyrie has made a nice collection of very nearly every small high-period oscillator found in 2022. An easy solution, I think, would be to rename the entry to something like "New oscillators" and give special attention to CatForce in the description.

Entry 11 should probably be named something like "New quadratic growth records".

I feel like I wasn't the sole discoverer of Raucci's p38; it was a completion of a wick by Jason Summers.

Jason Summers should also be credited as one of the authors. Possibly also cvojan for the discovery of traffic stop, but I'm less sure on this one. Generally, I think anyone who made a significant contribution to the specific pattern in some way should be credited. For example, I credited Noam Elkies in the new reflector periods entry for the discovery of the bouncer.

Should the strictly volatile p86 be in the nomination list? It's not there yet.

I second this nomination.

I support such a merge.

Editing the wiki now...

Done, I think. Replaced the "American Dream" #20 with the strictly-volatile p86.

What about the large amount of oscillators discovered in 2022?

See the first paragraph of Sokwe's last post. Seems like a good idea to me!
