OCA Discovery of the Year 2023 Nominations

[confocaloid]

>> If anyone does not like the mergers or deletions please speak up
I think I would prefer keeping all nominations in some form. (Possibly some merged, but not deleted.)

I would take out #14, as we do not know who made it, and it is just a program to simulate Izhora.

I believe it is made by Yoel (May 2023): https://scratch.mit.edu/projects/850492995

17. by Catagolue? P661 in B356/S23, https://catagolue.hatsya.com/census/b35 ... tdin/xp661

That impressively looking p661 oscillator in B356/S23 was found by FWKnightship:

P661:

Code: Select all

x = 63, y = 63, rule = B356/S23
28bo5bo$26bob2o3b2obo$26b2obo3bob2o$25bo11bo22$3bo55bo$b2o57b2o$2bo57b

11bo$26b2obo3bob2o$26bob2o3b2obo$28bo5bo!

My understanding is that seminatural high-period oscillators are rare in Life-like cellular automata, and this one is a statorless prime-period oscillator.

[b-engine]

A record in Hash2F: (Claimed by CasperWen8805181)
Smallest p46 knightship in terms of population (10 cells), but it has large bounding box.
The results are identified in LifeViewer. (Click the SHOW IN VIEWER in code box then press F6)

[NimbleRogue]

I change my vote to this camelship from an alternating rule by B-engine.

You can nominate as many patterns as you want

>> If anyone does not like the mergers or deletions please speak up
I think I would prefer keeping all nominations in some form. (Possibly some merged, but not deleted.)

Yeah, looking at it with a bit to think about it, removing all the deletions would be best. I have fixed the list, also I have made most of the mergers in Naszvadi's post, but for guns in Lifelike rules, and ships in Lifelike rules they maybe should be split, should I?

Here is my updated version:

toroidalet was the author of 31, and 32 was not this year, so take that out. 14 is by Yoel, and 16 is by FWKnightship as pointed out by confocaloid.

This is just an idea to try to simplify the nominations, If anyone does not like a specific merger please speak up, and can change it, also this is 100% my opinion

I would be extra biased, in merging my posts into this, so I have not done it

Here are the mergers
1-3 under. Omniperiodicity in Lifelike rules
4-8 under. Guns in Lifelike rules
9-12,OT unit stripes Layz Boi. under Turing completeness in Lifelike rules, and in just friends
13-16. under Metacells in engineered rules
18-20. under oscillators in Lifelike rules
21-22. under spaceships in Lifelike rules
26-27. under new ships in hexagonal rules

Here is what is left separate
17,23-25,28-31,33-38
oblique giraffeship in Glimmering Garden by GUYTU6J
Some spaceships in Harvest Moon by FWKnightship
B35e/S2-i36c by AlbertArmStain
Hash2 by b-engine
Factorio by H. H. P. M. P. Cole
Pyramid by NimbleRogue
Hexogen by Yoel Matveyev
*My Nominations

This version would have 40 separate candidates

[confocaloid]

Here is another nomination

How could I miss, I was wrong when recalled that p35 oscillator had been discovered before 2023! I encourage organizers to merge the above discoveries into one entry. However I am still unsure about whether B37/S345 replicator based technology should belong to circuitry/Turing-completeness entries or not...

This tiny spaceship in B0123456/S5:
[/code]
If it's too late, i'll just early-nominate this for the 2024 competition.

If this was a 2023 discovery then it's a totally fine nomination, but if it was discovered in 2024, then you will have to wait to nominate it, Can you link the post where you found this?

Yes, but you can nominate it for next year's thread

Also here is another nomination
Under Ouroboros ships
These are both by me

These are the first ships to have an Ouroboros(2)
viewtopic.php?f=11&t=3071&start=225
This rule has some almost Ouroboros ships The left ship in the current generation is an SMOS, because the right one can be composed of the left it is an SMOSMOS. In a different generation, the left ship is made from the right ship, and a still life, and without the still life, The ships would be Ouroboros(2)MOS

@organizers:
Corresponging life wiki entry is up-to-date? - https://conwaylife.com/wiki/OCA_Discovery_of_the_Year -. 2022 is totally missing.
Shall voting will be postponed till the end of the POTY2023?

[b-engine]

Should we start the voting?

[Naszvadi]

Should we start the voting?

Not yet, I'd recommend perform it after POTY'23, and of course till the corresponding OCADOTY lifewiki entry is not finished yet - 2022 is totally missing.

[Yoel]

I would take out #14, as we do not know who made it, and it is just a program to simulate Izhora.

I believe it is made by Yoel (May 2023): https://scratch.mit.edu/projects/850492995

It is just a program that simulates my Izhora2b computer (256x128 display with a keyboard). It took about 2 hours to build, nothing spectacular. The CA computer itself is here, built in 2021-2022:

Does anyone want to nominate anything else for OCADOTY2023?

In addition, NimbleRogue suggested that the many nominations should be grouped further for the sake of simplicity. Are there any groupings you would suggest?

[NimbleRogue]

Does anyone want to nominate anything else for OCADOTY2023?

In addition, NimbleRogue suggested that the many nominations should be grouped further for the sake of simplicity. Are there any groupings you would suggest?

I would suggest
Removing 18 A sawtooth based on a wickstretcher in Dropships, by Plasmath,
Removing 28 Pyramid by me,
Removing 48 First O(2) Ouroboros ship by me
Removing "an extensible SL in 3-4 Life" from 6.
Removing 20. Various oscillators in 2-state 1D rules.
Other possible ideas, that I am less sure about (especially the 4 mergers)
Removing 49. A 2-engine cordership made out of blinker puffers in B356/S23, by b-engine.
Merging 10, and 41 10. a p661 in B356/S23, by FWKnightship., and 41. The first odd period oscillator in Diamoeba, by bibunsekibun.
Merge 24, and 31. 24. B35e/S2-i36c, a rule with a OMOS which is made out of four 2c/5o ships, by AlbertArmStain., 31. A rule not too far off from Life that has speed- and slope-adjustable glider-based SMOS, by GUYTU6J.
Merge 44, and 46: 44. A spiralmaker in Flow6, by Redstoneboi. 46. A spiralmaker in the INT Generations rule 1e2-a3-cij4aijkrtz5cnqr/2ce3aejnr4aj5y6a/3 (A Wire-like World), by silversmith.
Merge 12, and 21: 12. Some constructions in B2i34cj6a7c8/S2-i3-a4ceit6in, including infinitely many oblique spaceships. 21. A giraffeship that is made out of five period-240 'cloverleaf' fake RROs, by GUYTU6J.

[Sokwe]

I would like to see this completed, but I don't want to organize it. I've at least created a wiki table for anyone to edit. If you can find the time, please add the generally agreed upon entries.

The OCA DOTY 2023 is being organized by Cyclotrons.
H._H._P._M._P._Cole Has compiled a set of nominations here: https://conwaylife.com/wiki/User:H._H._ ... ominations
I would have further refined the nominations, but I got no response to my previous post. I will include the 5 changes that I am sure about, and none of the changes I am not sure about. This would leave 46 nominations in total which feels like a lot, but it might be fine.

Should I copy the nominations to your version and work on the wording so it is more clear what each nomination means?

Merge 44, and 46: 44. A spiralmaker in Flow6, by Redstoneboi. 46. A spiralmaker in the INT Generations rule 1e2-a3-cij4aijkrtz5cnqr/2ce3aejnr4aj5y6a/3 (A Wire-like World), by silversmith.

I would remove 49.
I would not merge 10 and 41 as they are in different rules.
I would merge 24 and 31 under a single category, for lack of a better name I would suggest
I would merge 44 and 46 under 'Spiralmakers in Flow6 and A Wire-Like World'.
I don't think I should merge 12 and 21, as the constructions in B2i34cj6a7c8/S2-i3-a4ceit6in seem to be based on slow spaceships, while the giraffeship in Glimmering Garden is made out of p240 oscillators.

I will make these changes to my page, and if someone is unsatisfied with these I will revert whatever is unsatisfactory.

[NimbleRogue]

We need to set up a nominee table at the start of DOTY 2024 voting.
The format used by Carson_Cheng/Sokwe works great https://conwaylife.com/wiki/User:Carson ... inee_Table

Even though I prefer the format of Number, Name (with link), Authors, Description H. H. P. M. P. Cole's page could have worked great if a link to it was put in the topic post

I realized that the way that H. H. P. M. P. Cole and Sokwe set up their tables was completely different, and I just decided to format the nominations like they would be on the forums. In hindsight I realize that was probably the wrong decision, as there are a lot of editing that needs to be done.

Anyways, I reformatted everything on H. H. P. M. P. Cole's page. A lot of the nominations need major work on their descriptions. Unless some other people are willing to help me work on these then I would vote to just get rid of the descriptions even though they are helpful, and add a little more info to the titles. I know not having descriptions would be less then ideal, but I am worried that if there is not enough movement to work on these they will not get done until next year.

• #39 SoManyShips2: a 3-state rule with 2 failed replicator oscillators (one OMOS), a 4c/9 replicator, and over fifty small ships and several families of extensible ones. (by FWKnightship)
• #40 A 3-state rule with a SMOSMOSMOSMOS: This beats the previous record level of SMOS iteration by 2. Also, the SMOSMOSMOSMOS has a generation where you can see each of the smaller ships it is composed by, not just the SMOSMOSMOS. (by FWKnightship)
• #41W110 emulator stripes in Grounded Life, Just Friends, B3/S2, and B3/S0134V: (by many)
• #42 A new largest FIGseed: with a FIG value of over 379 million. The FIG value of a soup is calculated as FinalPop/InitialPop/Generations. The pattern is also really cool, it keeps on trying to form a square, but any remanent chaos on the square will lead to it growing further(by bibunsekibun)
