At last, the LOL constellation finds a use in a synthesis:

Code: Select all

That name makes much more sense, while the name Beethoven was coined because of autocorrect correcting Beehive.

Does xs19_696o6iozw343 have a synthesis yet?

Catagolue keeps this kind of thing pretty well up-to-date, usually within eight hours or so, so you can look for a synthesis yourself on the xs19_696o6iozw343 page -- and contribute a synthesis directly at the bottom of this page, if you find one.

The 8x32 soup includes this option

Code: Select all

x = 10, y = 19, rule = B3/S23
2o$2o7$2b2o$bob2o$bo2bo3$5b2o$3bo2bob2o$4b2obo3$5b3o!
but I don't think there's a way to get the southern blinker into place at T=1, with the only available 3G recipe:

Code: Select all

x = 19, y = 13, rule = LifeHistory
12.A.A$12.2A$13.A$16.A.A$A15.2A$.2A14.A$2A4$7.3D$6.D$6.5D!
Did you look at all two dozen soups before picking your good-possibility one? The junk at the lower left also doesn't seem to have an immediate solution with 3G recipes, so it might need at least a bit more cleverness.

EDIT: There's a recipe in an earlier soup that might be simpler. It could even be built with a slow salvo:

Code: Select all

x = 24, y = 20, rule = B3/S23
b2o$b2o$22b2o$22b2o$3o$2bo$bo2$22bo$21bobo$20bo2bo$21b2o$6b2o$5bo2bo$
6b2o11b2o$19b2o4$4b3o!
The 8x32 soup's synthesis reaction appears to be shared with several of the other soups. I think they're all variations on this simple long-running configuration, which is easy to make but unfortunately painful to clean up:

Code: Select all

x = 53, y = 77, rule = B3/S23

2G cleanup, here's hoping Catagolue doesn't mind the somewhat large space between gliders:

Fun fact: The two sparks disappear exactly one generation apart, and this mildly irritates me.

I couldn't seem to locate a later stage of this with 3G-constructible active messes. But even if I didn't miss something obvious, I bet there's something 4G, or some other clever trick with this or one of the other soups.

EDIT: xs19_gs2pd2kozx32 has only one soup, but it does allow for an obvious synthesis. Might be just about as ugly as the previous one, though:

Code: Select all

x = 39, y = 32, rule = LifeHistory

EDIT2: There's a nice soup for xs19_gs2pb8ozw346. Can this be made into a (not often usable) component?

Code: Select all

x = 11, y = 11, rule = B3/S23
8bo$8b2o$b6ob3o4$o$3o$3bo$2bobo$2b2o!
Re: the last edit above, I didn't find a way to make the pre-loaf and 6-cell spark entirely from above, so had to build the boat-with-tail after the spark synthesis got started.

Can somebody competent please rescue this component, if possible? I ended up doing a couple other evil and expensive things to get xs19_gs2pb8ozw346 to work:

Code: Select all

x = 234, y = 99, rule = B3/S23

A successful componentification would also allow for building harder stuff like xs26_0ok2qb4kozoie032... not that it's terribly likely that a recipe for that will be in high demand in the near future.

Found a few later lines of attack after another review. The resulting recipe is still awful, but maybe better than no synthesis at all. Or maybe not:

Is this worth cleaning up and getting into Catagolue?

If so, what's the current approved method? I thought I had come up with a way to build a recipe that Catagolue would accept, for xs19_gs2pd2kozx32. But the sesquipedalian-adjective unmagical box seems to have rejected it, and I'm somewhat relieved. I had to bring gliders in from weird directions to get them to clump up right, and use expensive constructed still lifes instead of single gliders to stop some post-construction active reactions -- just because the single gliders wouldn't have started interacting until after T=200.

Are any ideas percolating for ways to get the antimagical box to accept a wider range of valid syntheses? And is there any difficulty with setting that flag to prefer multistage syntheses over single-stage ones?

Another possibility: I'd really like it if there was a Catagolue/Shinjuku walkthrough, preferably in the Tutorials section on the LifeWiki, that explained step by step how to take a recipe like the one above and get it to show up as a synthesis in Catagolue.

I'll volunteer to write the tutorial, but first someone will have to explain all the behind-the-scenes nonmagical stuff well enough that I can understand it -- and for that to happen, someone might have to write a step-by-step walkthrough for me to follow.

EDIT: The recipe I found for xs19_gs2pd2kozx32 was something horrible like

Code: Select all

Near generation 360, spark_search told me that a blinker was a valid substitute for a substantial amount of junk. If this can be completed it will be a much more palatable synthesis:

Code: Select all

x = 21, y = 32, rule = B3/S23

Sorry I'm not sure what is going on with the Catagolue box and your other synthesis.

With a fresh eye, xs19_o44ria4z0db from a known 20-bit object, and xs19_o44ria4zc93 by extension. This gets us below 100 xs19s left.

Code: Select all

x = 189, y = 37, rule = B3/S23

Found with my 5 glider search script that uploads to the 5glider_stdin census; a reduction from 14g to 10g (which can possibly be managed to 9g or 8g with some cleanup optimization - I can't set up Seeds of Destruction on my computer for some reason)

Code: Select all

7G in fact:

Code: Select all

x = 77, y = 58, rule = B3/S23

I also can't get Seeds of Destruction to work, but gencols and the glider_destruction_v2.py script (made by gameoflifeboy) work wonders.

Nice! I thought of using the same starting still life but couldn't figure out anything from there.

There's still a scattering of unsynthesized 19-bitters with workable soups. Here's one, xs19_ciajk4ozw4701, that can be packed into the no-magic box. 15G:

Cleanup could no doubt be improved to two gliders, maybe just one but I doubt it.

19-bitters with theoretically known recipes that I don't think the no-magic box will accept (unless silly extra kickbacks are added) include xs19_8kiqjkczw4a4

Code: Select all

x = 37, y = 38, rule = B3/S23

19bobo13b2o$20bo6$bo$3o$ob2o$3bo$3b3o!
and xs19_gs2ar9a4zw32:

Code: Select all

7b3o2$13bo$13bo$13bo5$obo$obo$3o3$6b2o$6b2o2$2bo$bobo$bobo$2bo!
(these were mentioned on Discord yesterday).

EDIT: There's definitely a later stage of this that can build xs19_695mggkczw641, but which later stage is best?

Code: Select all

x = 43, y = 41, rule = LifeHistory
2.A$A.A$.2A2$27.A$26.A$26.3A2$38.A$38.A$20.D17.A$19.3D$19.D.2D11.3A3.

28.A.A$28.A!
Looks like there's a B-to-broken-H-to-LOM sequence that's common to all the soups except this one, so generally the same loaf+block+blinker+loaf+xs19_695mggkczw641 gets left behind.

Re: 19-bit still life syntheses

Post by Kazyan » January 30th, 2020, 1:24 pm

A refreshingly simpler one:

Code: Select all

x = 26, y = 30, rule = B3/S23
13bo$14bo$12b3o$16bo$4bo11bobo$5b2o9b2o$4b2o4$15b2o$10bo4bobo$11bo5bo

A variation on this will probably work for xs19_3pc0qmz4a43 as well, but I haven't figured it out yet.
