OCA Discovery of the Year 2023 Nominations

[Cyclotrons]

Rules from this 2018 thread apply. In essence: nominations should be interesting and nontrivial, and they should be from the 2023 calendar year.

Nominations will close when the voting thread is created, which will happen on February 1st, 2023 at earliest.

It would be appreciated if you include a short blurb for each of your nominations as to why they are so interesting to you.

[Disaster16439]

Here are a few suggestions:
Glider 3435(?) gun in Pseudo Life
New slowest spaceship(was that 2023?)
uhh...
My 187th post!
187=11x17

[hotdogPi]

Here are a few suggestions:
...
My 187th post!

2024, ineligible.

EDIT by dvgrn: reported with the comment "both nominations are from 2023", but without a link for the second suggestion I'm having a hard time verifying if that's true or not. The Pseudo Life gun seems to be confocaloid's from December 28, 2023.

[get_Snacked]

3-engine corderisation of an OT giraffepuffer, AbhpzTa
(at least) 3 OMOS's of a knightship, pipsqueek
OT unit stripes, 4.66920 16091 / Layz Boi / AlbertArmStain
oblique giraffeship in Glimmering Garden, GUYTU6J

just to get the obvious things out of the way. i like how everything came in threes (besides the 5-in-a-row giraffeship).

[NimbleRogue]

Some nomination ideas I had, In no particular order

Snowman's Rule with many natural ship speeds with no S0123
Most of the ships have a period of over 10, and The rulespace contains even more goodies. I found a rule in it with 14 natural/or semi-natural speeds, 13 with a period over 10, and 4 with a period over 100.
viewtopic.php?f=11&t=3120&start=875#p171928

muzik's self-inverse rules
These rules can retain symmetry through chaos, and will spontaneously form intricate rectangular tilings.
viewtopic.php?f=11&t=3120&start=825#p159773

FWKnightship's SoManyShips2 rule
It has over 50 unique ships, with many being super small, and with a lot of unique periods. In addition, there is a replicator that can be used for rep ships, an OMOS, many adjustable ones, including some with an adjustable slope, and more.
viewtopic.php?f=11&t=803&start=2850#p173530

FWKnightship's 3-state rule with a SMOSMOSMOSMOS
This beat out the previous record level of SMOS tetration by 2 and is beautiful to watch.
viewtopic.php?f=11&t=3071&start=225#p165761

GUYTU6J's rule with some glider-based SMOS from gliders bouncing between OMOS
I have not seen an SMOS made this way before, and also with a rule not to far off from life. The SMOS's can be constructed to be slope adjustable, as well.
viewtopic.php?f=11&t=3071&start=175#p156326

FlutterWithKSparkler's rule Marine Magnificence, with lots of small guns
This rule has to hold the record for the biggest number of natural guns, many are incredibly small.
viewtopic.php?f=11&t=6184#p169361

confocaloid's Wandering spaceships and manipulation via rule switches
This is the first and only spaceship that can switch randomly between 2 different rules, and never get destroyed, but where the transitions can affect its trajectory.
viewtopic.php?f=11&t=6182

May13's rule with 25 unique speeds
This is the record for most non-period adjustable ship speeds in a rule. Also, all the ships are relatively skinny and most are very long, and I find they have a different charm, than most other ships from search programs.
viewtopic.php?f=11&t=5175&start=125#p155492

[Period1GliderGun]

In terms of rules, I would like to nominate B35e/S2-i36c.

[b-engine]

I suggest that the thread should been pinned until the voting thread is created.

-

I nominated Hash2 for it's 3 records.

This is the smallest elemantary camelship in original LtL by me. It's also the most common overall. (Speed is (3,1)c/16, equals to 1/4 of lightspeed)
The rule also has about 68000 unextensible still lifes, also in the same rule. (The thread for Hash2 is shared with Hash1.)

Newest pattern collection is here.

-

2G constructible 215c/3489o puffer (dirty rep) that's the first elementary self-constructing puffer that I know:

Code: Select all

x = 6, y = 4, rule = B2in3-q4w/S23
2b2o$bo2bo$o4bo$b4o!

[confocaloid]

Some other Hash2 things:

This thread is for nominating discoveries from 2023 (rather than for posting new discoveries).

Edit: if those are from 2023, then it would suffice (and would be better) to add a brief description and link to the posts, instead of reposting everything here.

[b-engine]

This thread is for nominating discoveries from 2023 (rather than for posting new discoveries).

They're known since 2023. See this post.

[NimbleRogue]

Some other Hash2 things:

In the future, can posts about one nomination be kept shorter, or at least put all in one place, so the thread does not get cluttered?

I suggest that the thread should been pinned until the voting thread is created.

I would agree, this should be pinned until the voting thread is up, and the voting thread should be pinned when it is made too, I don't feel people are giving this enough attention. Last year we had less than half the number of people cast votes, as the prior year. Also, I know it's only the third, and we should give people time, but only 4 people who have nominated at least one discovery, and assuring a good diversity of nominations would be nice.

A few other possible nominations

The Upper limit for oscillator period with N cells in envelope box thread
H. H. P. M. P. Cole found the max period oscillator in a 2*3, 2*4, and many have worked on raising the lower bound for 3*4. H. H. P. M. P. Cole also found the 2*2 3 state case.
viewtopic.php?f=11&t=6047

Many Amazing RROs were discovered this year by Ampere, sophie<3, hotdogpi, and many others
Many of these have a high period loopability, are in non-int rules, or are just beautiful to watch.
viewtopic.php?f=11&t=3447&start=175

[H. H. P. M. P. Cole]

The Upper limit for oscillator period with N cells in envelope box thread. H. H. P. M. P. Cole found the max period oscillator in a 2*3, 2*4, and 3*3 box, and many have worked on raising the lower bound for 3*4.
viewtopic.php?f=11&t=6047

You seem to have missed out the 2x2 3-state case. The 3x3 case was found by Ampere in Discord a few years ago, so there is no need to nominate that.

Also, I calculated the maximum periods for n-state 1x1, 1x2, and 2x2 oscillators for n greater than or equal to 2, 3, and 4 respectively. They are in the same thread that you linked.

I am also nominating Factorio just in case.

EDIT: Nomination: Pyramid by NimbleRogue, which has a (92,1)c/818 spaceship

[NimbleRogue]

It seems based on others that it is ok to nominate yourself, so I'm nominating 2 of my discoveries.

The highest period INT ship by me
This ship is over 17 times the period of the next highest period ship which is dani's already crazy 6803c/403,840 diagonal spaceship, with a period of 729c/7,229,407o. Furthermore, the Rulespace has many high-period ships with some having periods over 100,000.
viewtopic.php?f=11&t=3120&start=875#p167733

An INT failed loop replicator rule by me
This Reploop grows in such a beautiful way. A single one will form a staircase of length 2, followed by a staircase of length 3, then by one with a length of 4, before breaking down. There is lots of interesting chaos in the interaction of loop replicators and the space between them.

[CasperWen8805181]

I nominate Hash2 also because it has (pretty sure) the smallest camelship in all HROT rules.

[b-engine]

I nominate Hash2 also because it has (pretty sure) the smallest camelship in all HROT rules.

It's already nominated. It has the smallest camelship in any original LtL rule (the only one supported by MCell) but not in HROT.

...
I nominated Hash2 for it's 3 records.

This is the smallest elemantary camelship in original LtL by me. It's also the most common overall.
The rule also has about 45600 unextensible still lifes, also in the same rule. (The thread for Hash2 is shared with Hash1.)

Newest pattern collection is here.

[FWCamelship]

Some spaceships in Harvest Moon by FWKnightship

Has the nomination threshold decrease significantly somehow?

[GUYTU6J]

Luka Okanishi (AbhpzTa)'s p1024 crawler gun in B36/S125 (2x2)
Yoel Matveyev's research into Hexagonal self-complementary rules, in particular Hexogen
---

oblique giraffeship in Glimmering Garden, GUYTU6J

just to get the obvious things out of the way. i like how everything came in threes (besides the 5-in-a-row giraffeship).

The giraffeship has a displacement of (3,12), three times (4,1), so it counts too
There should also be links from later 2023, with a credit to FWCamelship for finding sixteen 4-in-a-row xq795 spaceships (in private correspondence).

Consider merging one or more proposals of the following ranges:

• 1-3.
• 4-8.
• 9-12.
• 13-16.
• 17-20.
• 21-25.
• 26-27.
• 31-35.

My nomination ideas. Might intersect with former proposals. Might need grouping/splits

Wow, that is a big list, do we want to look over all the ideas posted so far, and consolidate them into fewer? In combo with this post, there is probably 50 or so unique nominations. On the other hand, having some people's nominations, or some people who were nominated, cut out before the actual vote may seem unfair. I can try to consolidate my nominations too.

[Naszvadi]

,,,, do we want to look over all the ideas posted so far, and consolidate them into fewer?
,,,

Looking over all? Basically this is the goal, and at least the supervising belong to the organizers. So feel free to consolidate/extend/do whatever with them whilst keeping fairness etc. Of course the list is biased and done by manually, so might contain errors, duplicates and probably there are some missing discoveries.

I suggest merging the Life-like gun discoveries into one entry, at least confolaloid's and AbhpzTa's novel guns in Pseudo Life and in 2x2, respectively.

[dvgrn]

Can someone please confirm (by providing a link) what the "new slowest spaceship" nomination was about?

hotdogPi's post got reported as incorrect information, which means I get dragged in to looking at it and figuring out what to do about it -- but neither the nomination nor the objection nor the post report give any actual information about what spaceship the nomination is talking about.

Is there anything new in 2023 that's slower than 2c/16394? And was the 2c/16394 actually discovered in 2023? So far I can't find any relevant posts on the forums or Discord, but I'm no expert on hunting for this kind of thing in the OCA world, so probably I'm just lost.

[confocaloid]

I believe those are items 31-32 in Naszvadi's list:

My post was a joke — it was the 187th post itself that was in 2024, not either of the actual nominations.

This is the slowest non-adjustable INT speed at 3c/136718o, and was discovered this year, but as mentioned above, I think the slowest speed in the post was talking about something else

Code: Select all

x = 6, y = 4, rule = B2-an3-ikq4-acqwy5-eknr6ae78/S02k3nqy4-ajk5-ekq6-i78
3bo2bo$b8o$2ob4ob2o$bob4obo!

[CasperWen8805181]

Edit: does not meet the rules, so deleted post.

[b-engine]

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

Code: Select all

x = 6, y = 4, rule = B2a67/S23|B3/S23
bo2b2o$ob4o$o2b2o$3o!

Pretty sure this is the smallest Camelship in a R1 Moore Neighborhood rule, if not, then any alternating rule.

It's discovered in 2024, not 2023. Do you own any notable discoveries?
