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

[b-engine]

Another nomination:

48782M (actually queen bee) which has very long lifespan.

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
The definition of an Ouroboros ship
viewtopic.php?f=7&t=2636&p=176560#p176560
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.

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:
