'Soul' for a pattern that forces its own existence in the previous generation. The logic being that they can't be constructed by mortals but only created by a god.

The pattern can easily be completed into a still life. Since the pattern inside it can't be created by anything else than itself, it's not glider-constructible (meaning that it doesn't have a glider synthesis). More strongly, this still life can't be constructed on empty space by any gadget whatsoe...

will the person who solves the uniquie father problem get the $50 cash prize even though john conway is deceased? Unfortunately, I doubt it. As far as I know, mtve never even got the other $50 for solving the grandfather problem in 2016. I have a feeling Conway was expecting both of these problems ...

This is one of the issues I have with the unique father conjecture: it's not precisely stated. Does it ask for an actual still life whose fathers must contain that entire still life, or is a still life-compatible patch enough? What does "some fading junk some distance away not being counted" mean? ...

Welcome to the forum! First let me say that this is a very impressive pattern! It's so cool to not just be able to run Lisp in Life, but even to type the code directly into the pattern rather than have it compiled. I was wondering if there are other instances where a high-level programming language ...

This command gave me a glide-symmetric 5c/6o instead of a symmetric one. What's wrong with it? ./lls -S cadical -b 10 9 -s p6 x5 "D2-" -p ">0" -r pB2ac345678/S012345678 x = 3, y = 9, rule = B2acn3cery4acenqr5einq7e8/S12eik3jnry4cik5ijky6ek7 bo$2o2$b2o$3o$bo$2bo2$2bo! The symmetry '-s p6 x5 "D2-"' s...

What is the smallest pattern with no polyomino parent? I suspect that the answer to this would be "the smallest Garden of Eden pattern". Most other patterns are probably glider-constructible, and it ought to be possible to create a highly artificial polyomino framework that consists of some lumps t...

The difficulty would be that simulating quantum systems with classical computers requires exponential time (at least as far as we know).

I think this research is amazing! It's exciting because it has the potential to tell us new things about the far future of the Life universe. In particular, it suggests that a replicator standing in a large field of ash could clear the area around itself and then build copies of itself into the clea...

I'm trying to use Logic Life Search to find some tagalongs. I thought I'd target the ones here: https://www.conwaylife.com/wiki/44P5H2V0 maybe not the easiest starting point, but still. Anyway: I create the search pattern, pass in the proper arguments, and get...a blank pattern. I am passing the -i...

Pedantic-ish-ness is perfectly welcome, but I'm not going to change this unless I can think of something to change it to. Is "grow uncomputably slowly" really a phrase that means anything that's relevant here? Yeah, I couldn't think of a better wording either. Don't worry about it. "Name any specif...

p37: making it the fastest-recovering known glider eater This is known to be the fastest possible. dvgrn 10/15 : adjusted wording to mention the computer-search proofs. p121: In fact, syntheses are known for all 78 297 strict still lifes with 19 or fewer live cells. Yes, but you probably want to upd...

In the GoE section, there's the statement it is currently unknown whether or not there exists a Garden of Eden that does not contain an orphan. This is false because it has been proven that every GoE contains an orphan. For example I give a proof here . This proof is not original to me, I simply dec...

OK, another question Independent of whether we have a constructor at both ends or not, has anyone built a Gemini-like spaceship that uses streams of LWSSs instead of gliders to store the instructions? This would be less compact overall, but it would minimize one of the dimensions. It seems straight...

I also think that the sprites for the like button should be switched, where it would be hollow by default and filled in when you like a post. This would give liked posts a higher contrast with the rest of the page, and stand out relative to other posts. If this is something we can pick I'd make it ...

"Highway murderer"?

The page itself https://catagolue.hatsya.com/object/xs0_0/b3s23 correctly says that the vacuum costs 0 gliders.

please check this preliminary summary out

By my count the order is correct, but #19 has one more point.

Well done all, especially to the discoverers of the Day and Knightships!

Is there a list somewhere of the bounties currently on offer?

Is there a way to constrain the population of each generation, rather than just the first one? Yes. In the develop branch you do -p followed by the population constraint, followed by a list of generations to sum over. So for example -p =40 7 means generation 7 must have a generation of 40. -p <100 ...

In order to create a Garden of Eden. Consider one cell. If it is ON it has 140 parents. https://oeis.org/A196447 The graph of that sequence is interesting. It has a sawtooth pattern where it jumps up and then gradually comes back down. I guess the jump up happens when the spiral reaches a corner? D...

They turned out to be somewhat inaccurate today, as confessed in the thread "More members needed in the Trump group" that I've reported

The alternative hypothesis is that ColorfulGalaxy wasn't hacked, and they just made a troll post.

Bump! real dynamic rule and a pattern which can probably break the record? x = 3, y = 1, rule = B2-an3-ciq4acikny5-aej6-ai8/S012-e3-in4-ej5-anr6-ci78 obo! (sorry for dp)Help!(looks like a near miss, though) I think this stabilises at around population 3.9642324e11. I didn't catch the generation tho...

Asking here for lack of a better thread: recently, the term "Pattern" in PoTY has become a bit of a stretch; a lot of the nominees are things like "34-bit still life enumeration", "Period-9 heavyweight sparker and associated R shuttle", "New growing spaceships", "New c/5 diagonal spaceships", and t...

This is a problem caused by the update from Python 2 to Python 3, which are slightly incompatible languages. In this case all that is needed is to replace all copies of 'xrange' with 'range'. # Golly Python script. Written by PM 2Ring, March 2009. Updated August 2009. # Modified for Golly 2.0+ by An...
