Still Life Synthesis Thread

[dvgrn]

I did an automatic search... and extracted the following improvements:

Code: Select all

xs23_04a96zg8jd59a4z01: 14 -> 5
...

There's a recipe that builds xs23_04a96zg8jd59a4z01 in five gliders? Where can I see this marvel? (I'm guessing I just have to wait a few hours until Catagolue catches up with its backlog?)

look at the moog_stdin soup in the sample soups section:

Yes, indeed, there it is! Part of what I was asking is whether anyone has gone through and submitted the improved syntheses to Catagolue. The page in question is still showing the 14G synthesis.

It's updated now. https://gitlab.com/hatsya/open-source/c ... 9689718493 took 40 minutes and updated 20696 objects.

It's updated now. https://gitlab.com/hatsya/open-source/c ... 9689718493 took 40 minutes and updated 20696 objects.

Probably it's worth noting that the line

Updating 20696 apgcodes: ['xp15_4r4z4r4', 'xp2_0111yf8kk8yd8kk8yf111zyfggypggzyf11y3ey9ey311zyd66yt66zooyzyooozyng8o0elle0elle0o8gzym1221y71221', ...

in the log doesn't imply there were this many updated objects. IIRC the apgcode of the pentadecathlon (xp15_4r4z4r4) is added automatically as an implementation detail. More importantly, many targets of glider syntheses aren't (strict) objects, and instead are pseudo objects, quasi objects, or constellations.

Hi, I am not too familiar with these reaction to produce and modify still life, I was wondering if there is a way to extend the the following:

Code: Select all

x = 71, y = 73, rule = LifeHistory

2A!

Also would be nice to know if that can be done from 1 side only, or a at least no NE gliders only, though I assume the most likely way to extend is symmetrical.

Probably most 1D structures, including fuses and c wires, are rake-buildable.

Details left to script magicians

[Jormungant]

Well, as it stands, only a rake of copperhead/fireship could manage this one, and I am not sure it allows p30 glider rake, probably needs several rakes to get this stream of glider at the needed speed.

My previous post has the synthesis components where the 3g tail synthesis components don't work. Since adding tails takes no more than 4g, 30-cell SL syntheses are not included here.

[PK22]

I tried to find a synthesis for a dimer of BTS, like that used in the Honey ring, and I found this reaction that produces xs36_wggc970bq23zbq2pg8421z23, which can replace xs36_wg8k970bq23zbq2pg8421z23, but I cannot find a way to synthesise the houses:

Code: Select all

8b2ob2o$8bo3bo$9b3o!

Note that while the traffic light + blinker produces only a B-heptomino, it releases sparks which perturb one of the houses, so it cannot be replaced.
Can someone help?
