What options are there for connecting something to the input and maintaining the 120-tick repeat time? This works: x = 54, y = 72, rule = LifeHistory 8.A3.2A$7.A.A2.A$7.A.A4.A$8.A.5A$10.A$9.A2.B2A3.A$8.A.3B2AB.A.A$8.2A. 3B.2B.A$11.6B$11.8B.B.B.B.B.B.B.B.B.B.B.B.B.B.B.B.B.B$11.43B$8.2B.43B $7.2A45B$...

Do you plan to make it as HashLife-friendly as possible? In that case, the design should avoid antiparallel glider streams, including those between neighboring cells. One solution could be to separate cells far enough apart, with distance on the order of cell size. The other one could be to make od...

Larger but better : a p48+24n adjustable rake (capped here). To increase the period by 24, move by (2, 4) the two spaceships at the back and the upper p24 rake. Impressive! By the way, the p24 rakes can be optimised by using the same Sprayer for suppressing the glider-block collision and emitting t...

And here is tha ATBC version, finally test ended ... I made a mistake not to store the sub result after all the gliders were reflected from the FSE. OK ... corrected, it is in the attachment as well. Incredible work! I'll link to this post somewhere more prominently because it deserves far more att...

[lengthy rant] I have been busy lately and unfortunately did not see this. I hate to bring this topic back up, but I want it to be absolutely clear: Any sort of discrimination based on gender or gender identity is a violation of rule 1 and will result in a ban. This includes intentionally referring...

I'm pretty certain it's possible to make a "universal eater"; a still life that is eats any glider that collides with it. But in a large soup it would immediately be killed by two gliders hitting it simultaneously. I don't have any idea whether it's possible to build a structure that can withstand ...

How do you run the search on the Cloud? These instructions explain how to do it in Google Colab, which gives you a few hours per day of free GPU time: https://gitlab.com/apgoucher/silk#option-i-running-in-the-cloud If you want a beefier computer and are willing to pay for it, then you can rent one ...

which developer kit should I use if it doesn't work?

What do you mean by "doesn't work"? What system (hardware + OS + GPUs) do you have, and what error are you encountering at what part of the instructions on https://gitlab.com/apgoucher/silk/-/blo ... /README.md ?

The "-r" option is a hack to skip the stabilisation of solutions and get raw results I'm somewhat curious about this option: I'd have expected that you'd need to print additional neighbour count information (e.g. the full 8 bitplanes) in order to know exactly how the pattern evolves. You're quite r...

I found 7 small new H-to-G converters using Silk: NE9T-13, SW12T124, NW15T85, NW18T95, NE4T27, SW6T133 and SW2T123 Nicely done! And these settings: > silk -r -s 40 in.rle 28 28 7 >out.txt This yielded 477208 results. The running time was about 6 hours on an Ec2 g6.xlarge instance. For these sorts o...

... And the other thing is, reading a 2D stable memory to retrieve single-channel salvo information is very likely going to be painfully slow. Yes, if you're using a stable storage mechanism then an ECCA would be a better choice of construction arm than a single channel aimed at a SPEBOE. Single-ch...

I just got the idea to store single channel construction recipes for common circuitry components in the 0E0P metacell, e.g snark, Scrobie splitter. And then if it needs to create a reflector or splitter, it has a whole bunch of them in its memory loops. The idea of subroutines is a very appealling ...

Thanks for the suggested change! I've made some more progress: x = 1297, y = 1108, rule = LifeHistory 451.2A95.10B.4B2.2A2B$451.A.A95.10B.4B.2A3B$453.A4.2A90.10B.4B2.4B$ 449.4A.2A2.A2.A89.10B.4B2.4B$449.A2.A.A.A.A.2A90.10B.4B2.4B$451.BABAB A.A94.10B.4B2.4B$452.B2ABA.A95.10B.4B2.4B$453.2B.BA97.10B.4B...

ECCA where finding SoD is (I hope) in progress I'm on vacation this week so I managed to find some time today to make more progress on the seed of destruction; here is the current status: x = 1297, y = 1108, rule = LifeHistory 451.2A95.10B.4B2.2A2B$451.A.A95.10B.4B.2A3B$453.A4.2A90.10B.4B2.4B$ 449....

Pslmake is on 1% (after about a day) building the pattern seed, I expect the salvo could be finished in about 40-60 days ... if there will be no additional problem to solve. I thought that the seed to be constructed would be the spacefiller seed -- it more effectively demonstrates the universality ...

There have been a few updates to Silk today: mvr has added new options --exempt-existing (a boolean flag that excludes catalysts in the input file from counting towards the active region bounds, matching Barrister's default behaviour) and --max-perturbed-time N (an integer to limit how long the cata...

I'll need to think how to quickly determine whether an oscillator is trivial. How quick does it need to be? Are there so many that it might take a substantial portion of the CPU time? Absolutely, yes! For example this found 8272 oscillators of period >= 11: +---------+------------------------------...

by default it discards oscillators What is the reason for this? I would think it would be nice to output the higher-period (p>10) oscillators by default, as long as checks could be done to discard trivial oscillators and oscillators with known rotors (like with dr's knownrotors file ). I worry that...

I think that block is what's causing the problem, and in any case it's not necessary (Silk uses Floyd's cycle detection algorithm, so it will recognise when it becomes periodic with p256). I tried that now, and removing the block does help for that particular problem. Could it be that this problem ...

Did you mean to draw the block in white (state 3) so that it's treated as a catalyst? No, sorry I should have mentioned that, I put it there as part of the input pattern just to have a known result when no catalysts are placed in the blue area, because of the grid being a torus. I think that block ...

or removing the -s option, for example: > build/src/silk -s 7 in.rle 4 4 2 that result isn't found anymore. I don't think that can be the expected behaviour. Can anyone else replicate this? Did you mean to draw the block in white (state 3) so that it's treated as a catalyst? Otherwise the block is ...

With this amazing new tool we will need a Silk thread now right, so I went ahead and created one. Previous Silk-related posts started here Thanks for creating this thread! I've taken the liberty of moving the posts from the other thread here. There's also a (more active) discussion on Discord: http...

and the blue cells represent where the white colored catalyst can be placed The problem is that Silk is much more like dr than like CatForce. MathAndCode explained it very eloquently here: There are two ways to think about ConwayLife: cell-based and pattern-based. The cell-based approach focuses on...

1. Why did you choose the name “Silk” over the remaining Hunting of the Snark characters There are two complementary reasons: The term 'silk' refers to a senior barrister (at least in England and Wales), so this is apt for an improved* version of Barrister: https://castleassociates.org.uk/ask-the-e...

Thank you for your help, I still have a few questions: Is there any other tools needed that are not packaged into Silk? It has dependencies on CMake and nvcc -- but if you're using the Google Colab then you won't need to worry about installing anything, because it doesn't run on your computer; it r...
