POTD 2010 Nomination Thread

[testitemqlstudop]

Every pattern found in a year matching the regex /201[0-9]/ is allowed.

Use the same rules as POTY 2019. Any pattern in the first 3 ranks of any POTY this decade is automatically nominated.

[Sokwe]

Again, I think we should put this off until the Pattern of the Year 2019 competition is concluded.

[Ian07]

Okay so I have a question: when do nominations end for these competitions? (POTY, POTD, OCADOTY)

It's important to note that if all three top-3 entries are automatically nominated for POTD, then we should wait for POTY 2019 to finish so we know what those are.

[Moosey]

Here are my nominations again:

I nominate all the POTY winners from past years to POTD, in particular, Sir Robin.

I also nominate David Hilbert for POTD

Should anyone happen to discover a new elementary spaceship within the next 33 hours and 1 minute, (time of writing: 14:59 UTC) I nominate that too

As it happens, Scholar was discovered within that timeframe, (and happened to be given a name I suggested), so I nominate that as the second elementary 2c/7 in over 19 years.

[blah]

Maybe we should hold a vote for POTM (years 1000-1999). Not to be confused with POTM (2019-12-01 - 2019-12-31). (Or POTM (2019-12-30)?)

[GilGil]

I propose as a candidate the waterbear.

[Ch91]

Maybe we should hold a vote for POTM (years 1000-1999). Not to be confused with POTM (2019-12-01 - 2019-12-31). (Or POTM (2019-12-30)?)

It would certainly be a discovery to find that CGoL existed before 1971, that's for sure.

It would certainly be a discovery to find that CGoL existed before 1971, that's for sure.

But it wouldn't be a discovery at all, just a surprise of infinite improbability, to find that John Conway, currently professor emeritus at Princeton university, existed before 1937. That's for certain!

Since I still haven't gotten an answer about how the 2019 patterns to be nominated to POTD will be determined (again, this really should be happening after POTY is completed), I guess I'll be nominating David Hilbert and the spider synthesis manually. I'm pretty sure those two will be in the top 3, though I don't know what the other one will be.

WOW! The David Hilbert aka p23 is just as boring as it might have already been when the early roman catholics slaughtered the renowned and respected librarian Hypatia of Alexandria, burned down her library and expelled the bourgois hebrew inhabitants of the ancient greeks capital because they couldn't distinguish a temple from a synagogue.

But the spider synthesis is by far the most exciting intelligent design I became aware of ever since I joined this digital forum of Conway fans, addicts and enthusiasts a fortnight ago.

Is it time to drop the nuke? I think it's time to drop the nuke. The USA is otherwise considering a ground invasion of Japan, which would have an estimated cost of two million casualties—wait, this is Conway's Game of Life, not real life!

Dear Extrementhusiast!
Are you aware that Hiroshima and Nagasaki in Japan, Sodom and Ghomorra of the atomic ages, happened hardly three quarters of a century ago in 1945 due to the extraordinary mathematical skills of
J. Robert Oppenheimer?

[Sokwe]

Things are getting a bit too off-topic here, and I think it's difficult to nominate patterns when we don't yet know what will win the PotY 2019 competition. I have decided to lock this topic for now. I will unlock it when the PotY 2019 competition concludes.

[Sokwe]

With the completion of the 2019 Pattern of the Year competition, it is now time to unlock this topic.

As already stated, the first 3 ranks from each Pattern of the Year competition are automatically nominated (not including 2012, since no votes were cast). I think this is a reasonable starting place. However, there are certainly a few other patterns that deserve to be nominated. I have two specific nominations:

• Spaghetti monster: the first 3c/7 orthogonal spaceship to be discovered. It's discovery required significant improvement to search techniques by Tim Coe.
• Merzenich's p31: the first p31 oscillator. This represents one of only four new oscillator periods found in the last ten years.

I think we somehow need to include the still life and spaceship syntheses that have been found over the decade. Syntheses tend to build off each other, so they are significant as a collection. For Pattern of the Year competitions we have often included these by nominating related synthesis collections. What could be done to include these in the Pattern of the Decade competition? Is there a fair way to nominate them?

If anyone has any other nominations, please share them. Almost certainly, any nominee would come from the previous Pattern of the Year nominees.

[Ian07]

I know I initially said I wasn't going to nominate these, but since we're automatically including the top 3 from each year I felt it wouldn't be fair to exclude them just because a vote was never held for 2012:

• Statorless p3: the first volatility-1 p3 oscillator found.
• 37P4H1V0: smallest c/4 orthogonal spaceship known.

(P.S. don't forget about OCADOTY 2019)

[Sokwe]

I have temporarily locked the new voting thread so that we may finalize the nominees, rules, and time-frame for this competition. I am including here the current (unedited) list of nominees from the voting thread:

[Sokwe]

I have a few immediate comments.

• I think it is essential that we nominate the still life and spaceship syntheses found over the decade. I am of the opinion that the small still life syntheses could be nominated as a single collection. This includes syntheses of all still lifes up to 18 bits, and cheap (less than one glider per bit) syntheses of all still lifes up to 17 bits.
  
  I'm not sure if the spaceship syntheses should be combined into a single entry. One issue is that the spider synthesis automatically has its own entry as one of the top 3 from the 2019 Pattern of the Year competition.
• The reverse caber tosser entry should use 35 gliders, not 32, as this was the state of the art at the end of the decade.
• We could combine some subsequent discoveries into already-nominated categories (e.g., add the quinti-Snark to the stable pulse dividers entry). Does anyone agree with this? The way I see it, in the pattern of the decade competition patterns no longer need to be grouped by the year they were discovered.

[Sokwe]

I want to get the voting thread back up and running, because bubblegum worked hard at it and we have waited a long time for it.

By the way, if anyone opposes my... intervention, and just wants me to start up the contest again without changes, please feel free to comment. I'm wielding my moderator power a bit heavy-handed here, which I don't really like to do.

I propose the following nominees:

• Still life syntheses: syntheses of all still lifes up to 18 bits, with all still lifes up to 17 bits synthesized with less than one glider per bit (Martin Grant, Mark Niemiec, Tanner Jacobi, Chris Cain, Goldtiger997, Jeremy Tan, et al.)
• Small spaceship syntheses: syntheses of a variety of small spaceships, representing a significant advancement in glider synthesis technology (Martin Grant, Tanner Jacobi, Aidan F. Pierce, Adam P. Goucher, Goldtiger997, et al.)

I also propose that we add the statorless p5 to the statorless p3 entry. I would want to add the CC semi-Snark to the pulse-divider entry, but since it was in the top 3 for its year, it automatically gets its own entry. I realize now that the quinti-Snark doesn't fit with the stable pulse dividers.

Some corrections to and comments on the current entries:

• Ivan Fomichev's name is misspelled.
• Scholar is an orthogonal spaceship, not a diagonal spaceship. Further, it is the second elementary 2c/7 ship, but not the second overall.
• The note about the size of the OE0P metacell seems unnecessary, since I don't think large size is considered a desirable quality in this case.
• As noted before, the cost of the reverse caber-tosser should be 35 gliders, not 32.
• The 2-engine Cordership entry should specify that it is the least known number of switch engines for a Cordership.
• Regarding Tanner's p46, I would include the fact that it can be used to construct gliderless LWSS and MWSS guns.
• Regarding the syringe, I would remove the mention of the H-to-G and Snarks.
• I think Garden of Eden 6 is still the only known Garden of Eden to fit inside a 10x10 bounding box. Is this true?
• Spaghetti monster is the first and only known elementary 3c/7.

I have a few opinions on rewording some of the descriptions to be a bit more clear, and I prefer the format we've been using for the list for the last few PotY competitions. Here is how I think the updated list should look:

Finally, we need to decide how long to allow for voting. We typically give it two or three weeks for the Pattern of the Year competitions.

Again, I would appreciate some feedback on this, as I don't want to delay the contest any further. I especially want to know if anyone objects to my two latest nominees.

[Hunting]

May I sneak Naszvadi's new smallest c/5 puffer in?

[Sokwe]

May I sneak Naszvadi's new smallest c/5 puffer in?

This competition covers the years 2010 through 2019. That puffer was found in 2020, so it does not qualify for this competition. However, it certainly qualifies for the next Pattern of the Year competition.

No objections here -- but then, I did something similarly heavy-handed on the last voting cycle. It seems like somebody has to do a really careful read-through and review in advance of votes like this, so thank you very much for stepping in!

You've fixed all the problems that I noticed with the original list, and added only items that I might want to vote for... so if there are other mistakes, somebody had better speak up about them quick. All I can see is a stray 'a' at the end of #15, but I'm going to go ahead and use my heavy-handed moderator powers to make that disappear right now.

[calcyman]

syntheses of all still lifes up to 18 bits

should read '19 bits': https://catagolue.appspot.com/census/b3 ... costs/xs19

(Martin Grant, Mark Niemiec, Tanner Jacobi, Chris Cain, Goldtiger997, Jeremy Tan, et al.)

I think Alex Greason needs to be added to that list.

I also propose that we add the statorless p5 to the statorless p3 entry. I would want to add the CC semi-Snark to the pulse-divider entry, but since it was in the top 3 for its year, it automatically gets its own entry. I realize now that the quinti-Snark doesn't fit with the stable pulse dividers.

Hmm, yes, I really like these "whole is greater than the sum of its parts" meta-entries (such as the glider syntheses) -- it helps to make POTD (Patterns of the Decade?) overlap less with POTY. In that vein, I'd suggest "single-channel universal construction" as an entry: after all, the Snark, syringe, and universal 90-tick-recovery recipes were discovered this decade, as well as slmake and various constructions dependent upon it. So this entry actually makes sense for POTD but not for POTY (because it's a collection of discoveries that spanned many years).

Can someone with more knowledge of this entry and its uses (and its discoverers) provide a description for it?
