OCA Discovery of the Year 2018
OCA Discovery of the Year 2018
Happy new year, fellow lifers.
The OCA "D"OTY has certainly not been around that long; if I remember correctly, last year was the first one, organised and its results announced by yours truly.
We followed the same voting system as with the CGoL POTY, which I think worked very well and showed a fairly accurate representation of the general agreement. That is the one star, two stars, three stars voting system (where you can vote for as many candidates as you want).
For reference, here is the voting for the OCA DOTY from last year. Here are the candidates.
General Rules
It is probably good to favour engineered patterns, solved problems or conceptual ideas (such as the winner from last year) and projects that require addressing a challenge. The candidates should either be interesting enough in their own right for any reason (examples from CGoL include Copperhead) or have the potential to make an impact in some way in the future (such as the Snark).
Rules are allowed as candidates. However, please don't mindlessly nominate rules unless they have been VERY prolific and their dynamics have been explored in depth. A good example is Snowflakes, which was part of the competition last year*.
Nominations open until 15/01/2019 00:00 GMT at the earliest.
* It was actually hard to imagine that Snowflakes would have been developed so much during 2018 though! If the main project that was underway with all the SS constructions had been completed by now, it would be a strong contender.

Re: OCA Discovery of the Year 2018
I've only really been here for the latter half of the year, but I'd definitely like to nominate AforAmpere's adjustable slope ships.

Re: OCA Discovery of the Year 2018
#02 2718281828's RROs are really cool.
#03 Danny's tlife puffer, and AbhpzTa's ship from it.
#04 Other adjustable ships by AbhpzTa, muzik, wildmyron, 2718281828, and me.
#05 The slowest ships ever, by LittlePeng9, translated into a RULETABLE, and into spaceships by me.

I manage the 5S project, which collects all known spaceship speeds in Isotropic Non-totalistic rules. I also wrote EPE, a tool for searching in the INT rulespace.
Things to work on:
- Find (7,1)c/8 and 9c/10 ships in non-B0 INT.
- EPE improvements.

Re: OCA Discovery of the Year 2018
I can't really think of many individual OCA patterns that would notable enough besides the already nominated adjustable-slope ships, but there were numerous interesting rules. The ones most fitting the "specifications" would probably be:
- Hype (B2-ac3aei4ae6i8/S23-ejq8), a rule which contains a very large variety of high-period oscillators, has been heavily apgsearched (the third most of any non-totalistic rule) and has been proven omniperiodic.
- Suns (B2ei3aeij4cjt5ky6ei/S1c2ace3jkn4aeijktw5ekry6in7e), a rule featuring complicated hassling mechanisms of a high-period oscillator, which has also been proven omniperiodic.
- ATPP (B3-ckq4z/S2-c3-a4iq5k6k), a rule featuring unusual failed-replicator spaceships, actual replicators, many linear and quadratic growths and even a large, engineered spaceship by toroidalet.
- Arrow (B3-jkn4a/S1e2-a3ijnry4n)
- Emitters (B2i3ai4cei5c6c7/S2-ae3acein4-t5-aq6cei7c8)
- Hive (B3-ry4ckn/S2-in3-cjn4it5aiky6-a7e8)
- Omosso (B2k3acijr4ijqy6i7c/S2aek3ijnqr4it5n)
Isn't this essentially the same as the "adjustable ships" entry from the 2017 competition (#01)? The #05 entry is pretty similar to 2017's #06, also.AforAmpere wrote:#04 Other adjustable ships by AbhpzTa, muzik, wildmyron, 2718281828, and me.

Re: OCA Discovery of the Year 2018
I'd like to nominate my own list of 2-cell oscillators for every period up to 102.
Re: OCA Discovery of the Year 2018
Mine:
Weak Turing-completeness - weak(?er?)-universality - but at least proving logic universality of the following Glider supporting rules with explicit meta unit cell constructions - meta-polyglots, for the first, there is a custom software:
The following one based on some cool results of AbhpzTa from ../forums/viewtopic.php?f=11&t=376&start=725#p55465
Remark: AbhpzTa's XOR reaction is especially cool in one of the mentioned rules above.

Re: OCA Discovery of the Year 2018
Since there haven't been very many other entries, I've decided I'll nominate these four as well!77topaz wrote:Other rules I think would be worth nominating but should maybe be seconded by someone include:
Re: OCA Discovery of the Year 2018
toroidalet's methuselah in a 2-state isotropic rule, estimated by calcyman to last at least 2^2^50 generations. I'm not sure if it's known for certain that the pattern will stabilise, so if that's a problem for the competition then I'd like to nominate the pattern which lasts approximately 3.455*10^532 generations instead.
Edit:
AforAmpere's discovery of 8c/9 spaceships in a 2-state, isotropic rules (without B0) - I believe this is the fastest sub-lightspeed orthogonal spaceship known in this rulespace.

The 5S project (Smallest Spaceships Supporting Specific Speeds) is now maintained by AforAmpere. The latest collection is hosted on GitHub and contains well over 1,000,000 spaceships.

Re: OCA Discovery of the Year 2018
I'm pretty sure that it stabilizes due to simulations where the fuses were prematurely terminated, although I haven't run it to completion, even the first part, for obvious reasons. However, I am confident that after the main really long domino pair sequence burns down, it creates another fuse and burns through that. A compromise is the second one posted, which will also stabilise eventually, after somewhere on the order of 2^200,000 generations based on a rough and inaccurate estimate of burning through 100,000 duoplets.wildmyron wrote:I'm not sure if it's known for certain that the pattern will stabilise, so if that's a problem for the competition then I'd like to nominate the pattern which lasts approximately 3.455*10^532 generations instead.
I think the main point of this one was the discovery of many new displacements and periods of adjustable ships, culminating in the adjustable-slope ships and the adjustable-displacement ships (2019).77topaz wrote:Isn't this essentially the same as the "adjustable ships" entry from the 2017 competition (#01)?

Re: OCA Discovery of the Year 2018
Yeah, I could not have found the adjustable-slope ships without the work done just before it. Unless we want to consider that part of the same nomination as the adjustable slope ships. That is why I nominated all of the other work people had done, which I feel was crucial to the subject as well.toroidalet wrote: I think the main point of this one was the discovery of many new displacements and periods of adjustable ships, culminating in the adjustable-slope ships and the adjustable-displacement ships (2019).
I manage the 5S project, which collects all known spaceship speeds in Isotropic Non-totalistic rules. I also wrote EPE, a tool for searching in the INT rulespace.
Things to work on:
- Find (7,1)c/8 and 9c/10 ships in non-B0 INT.
- EPE improvements.

Re: OCA Discovery of the Year 2018
I am currently snowed under with work so, if someone else would volunteer to prepare the competition, I would be very grateful.
Re: OCA Discovery of the Year 2018
Sorry, not volunteering to prepare the competition, but if it's still possible to nominate a late entry, I'd like to do so:

I could do it, especially since I already have a spreadsheet set-up for the CGoL POTY 2018 competition that I could reuse.Rhombic wrote:I am currently snowed under with work so, if someone else would volunteer to prepare the competition, I would be very grateful.

Re: OCA Discovery of the Year 2018
Okay, then, are we all in agreement to have this be the list of entries?
(EDIT: For some reason I thought Oscar Cunningham was named Alexander. )
- #01 Adjustable slope ships (by AforAmpere)
- #02 RROs in various rules (by 2718281828)
- #03 tlife puffer and the ship based on it (by Luka Okanishi and Dani)
- #04 Other adjustable ships (by Luka Okanishi, muzik, Arie Paap, 2718281828 and AforAmpere)
- #05 Record slowest ships (by LittlePeng9 and AforAmpere)
- #06 Hype (B2-ac3aei4ae6i8/S23-ejq8): a rule which contains a very large variety of high-period oscillators, has been heavily apgsearched (the third most of any non-totalistic rule) and has been proven omniperiodic.
- #07 Suns (B2ei3aeij4cjt5ky6ei/S1c2ace3jkn4aeijktw5ekry6in7e): a rule featuring complicated hassling mechanisms of a high-period oscillator, which has also been proven omniperiodic.
- #08 ATPP (B3-ckq4z/S2-c3-a4iq5k6k): a rule featuring unusual failed-replicator spaceships, actual replicators, many linear and quadratic growths and even a large, engineered spaceship by toroidalet.
- #09 Arrow (B3-jkn4a/S1e2-a3ijnry4n): a rule featuring a family of adjustable rakes and a large variety of shuttles and rake interactions.
- #10 Emitters (B2i3ai4cei5c6c7/S2-ae3acein4-t5-aq6cei7c8): a rule featuring a very large variety of small high-period oscillators and guns.
- #11 Hive (B3-ry4ckn/S2-in3-cjn4it5aiky6-a7e8): a rule featuring many spaceships and oscillators of strange speeds based on failed replicators.
- #12 Omosso (B2k3acijr4ijqy6i7c/S2aek3ijnqr4it5n): a rule featuring two small, high-period spaceships, a natural RRO, and a large number of distinct OMOSes.
- #13 CA simulating the bf esolang (by M. I. Wright)
- #14 List of 2-cell oscillators for every period up to 102 (by Oscar Cunningham)
- #15 Turing-completeness/universality proofs and Rule-110 unit cells (by Peter Naszvadi, Luka Okanishi and LaundryPizza03)
- #16 JvN loop-based replicator (by fluffykitty and Redstoneboi)
- #17 Exponentially long-lasting methuselahs (by toroidalet): fuse-based methuselahs of which one is known to last for 3.455*10^532 generations, and another has been estimated to last at least 2^2^50 generations.
- #18 8c/9 spaceships (by AforAmpere): the fastest known sub-c spaceships in a two-state isotropic rule without B0.
(EDIT: For some reason I thought Oscar Cunningham was named Alexander. )

I would also nominate the dominoplex orthogonoid.

Re: OCA Discovery of the Year 2018
That was discovered in 2019. Also, I think that list is good 77topaz, unless anyone disagrees. I think everything in this list is great, so it will be hard to decide.
I manage the 5S project, which collects all known spaceship speeds in Isotropic Non-totalistic rules. I also wrote EPE, a tool for searching in the INT rulespace.
Things to work on:
- Find (7,1)c/8 and 9c/10 ships in non-B0 INT.
- EPE improvements.
