I've had enough of these "challenges".

I see potential in Polymath Project-like collaborations to solve things like these. We work on such problems primarily for fun, we do what we can, yes. What I'm saying is that monetary prizes "perpetuate the myth of the lone genius", as I recall one criticism of the Fundamental Physics Prize (US$3 m...

I can interpret the Rule 30 Prizes as kinds of vanity prizes, somewhat like the old Eternity Puzzle. They are vanity prizes because Stephen Wolfram defined Rule 30 (and the rest of the elementary cellular automata) first. It's like saying "here's my puzzle, solve this and you win some money". The di...

This thread is for collecting syntheses of all 19-bit strict still lifes. The 17- and 18-bit syntheses have all been completed, the former in strictly less than 1 glider/bit. It seems natural to now push to 19 bits, which is the upper limit of the explicitly mentioned still lifes in one of Shinjuku'...

Another unreasonable number appears to be the 930 currently unsynthesized xs19s.

If anything, that is the next goal I want done. You have unlimited gliders for this "19-in-any" project, so the pressure should be much less than in any fixed-glider challenge.

And I have made a thread for it.

You do not need to be 18+ to view a list of apgcodes. I need a forum admin to upload the 43 MB zip file here. Anyway, the original location of said file was in my Google Drive here ; I am merely looking for a place more permanent than Google Drive to store this. There is also a cheekier point. A ra...

I've made a Patreon post with an attachment listing out Niemiec's (corrected) original tabulation of all strict and pseudo still lifes to 24 bits, with apgcodes.

Of course, the attachment is too large to upload directly here, so it is there.

Will HTTPS support (via HTTPS Everywhere) be added?

I should have done that now.

@Freywa I've submitted all objects/constellations (with a semiperimeter <= 40) with 3G syntheses that don't already have 3G syntheses in Shinjuku: https://gitlab.com/parclytaxel/Shinjuku/merge_requests/40 This should be helpful for Alex Greason's collision search, since it will have 14000 new small...

well x = 8, y = 3, rule = LifeHistory 2.2E2.2C$E2.E2.2C$3E! The only problem is that it doesn't eat all centuries without interfering with the reactions that produce them, such as in the bistable switch: x = 39, y = 56, rule = LifeHistory 12.A.2A$12.2A.A2$10.5A$9.A2.A2.A$9.2A3.A.A$15.2A13.3A$30.A.A...

I had just proofread the entire Principia of Newton (in around twelve hours), and I have accepted the merge request.

It appears that 92 xs18s remain.

We should also add syntheses for the xs18s for which Shinjuku/Cata doesn't know any synthesis. They were completed in 2017, right?

Regarding The Last One, we could start with a hook-with-tail and bang on the remaining nine bits.

#266 in 16 gliders: I was expecting a method that added the requisite ten bits onto the snake, so that two still lifes could be solved in one go, for both pairs in the last six that have this feature. The final 5. I had pushed an RLE of the last six stills only a few posts above. Why would you want...

Yes, but this project is for everyone's sake, whether we know them or not.

I am, by maintaining Shinjuku. I've essentially reached the limit of my capabilities for the actual syntheses, and am merely collecting what Kazyan and Martin and those who can do the syntheses are doing.

It's not funny; it's just a method that works.

And I want the last remaining stills to be solved by the end of September.

Priority should be given to solving these three pairs of still lifes: x = 56, y = 29, rule = B3/S23 b2o$bo21b2o3b2o19b2o3b2o$3bo19bo2bo2bo19bo2bo2bo$2b2o21b2obo22b2obo$bo 24bob2o22bob2o$o2b3o19bo23b3o$b2obo19bo24bo$6bo17b2o$5b2o12$b2o$bo21b 2o24b2o$3bo19bo2bob2o19bo2bob2o$2b2o21b2obo22b2obo$bo24bo2b...

I don't think you'd be able to improve on the 16-glider synth I added to Shinjuku myself with those kinds of constructions.

The problem is that I've already committed it myself.
