Synthesising Oscillators

[dvgrn]

and get the funny feeling that Catagolue is going to reject this for some unseen reason, but this seems fine to me so far. If there's no xp856 entry on the syntheses list when I wake up, then I'll at least know something is wrong, while knowing absolutely nothing that is actually wrong.

As it turns out, Catagolue did seem to reject it...

Your previous submission did get processed, since there's a 24G xp8 in there now, but the next stage should be a 37G xp8 with three galaxies, and that one isn't showing up. My guess would be the same as yours, that that next stage might have gotten mis-identified because there are gaps in the middle of a stage with more than 20 blank columns. I could be wrong about that, though.

Your synthesis is fine, but it could use a little more optimization. For example, there's no reason to build the two-beehive bait for the second galaxy construction linked to above, using a kicked-back glider. That constellation is symmetrical, so just flip the recipe around! So that will be 23 gliders for that stage.

Breaking up the recipe into more stages can help make this kind of thing easier to see. Going to fewer stages is often a step in the wrong direction, when you're trying to figure out exactly what is making Catagolue unhappy.

Then toward the end you build five LWSSes using four gliders each, for no apparent reason. A 3G recipe will work fine, just maybe construct the LWSSes a little farther away.

For the last of the five LWSSes, octohash suggests an interesting alternate option for starting up the Herschel loop. There's exactly one result in the octohash database for the active reaction that you see after a Herschel has gone through a dependent-conduit block:

That will save the LWSS+glider cost plus two more cleanup gliders plus the cost of the block, minus one activation glider. If that doesn't work for some reason, there are definitely other cheaper ways than the LWSS+glider method you used, to get a B-heptomino (or better, a pre-Herschel that doesn't need the block cleanup).

Amazingly, there's even a 3G way to build that hivenpond constellation, so if the obstructing block can be built later without too much extra cost, it will be a pretty good improvement:

It wouldn't surprise me in the slightest to find out this actually has been synthesized before, and that this was all for nothing...

Can't be all for nothing, as long as it's good practice for future synthesizing!

Heh, yup, the current recipe uses five (FIVE! yikes!) gliders for each of those blocks, but they can just as easily be done with two, which gets rid of the rest of the wild LWSS-building.

So if you just take out the southmost block construction, and replace it with the 3G hivenpond recipe... then you'll be getting to where my very limited synthesis ability can't suggest any more improvements, and somebody with more synth-fu will have to take over.

I wouldn't be surprised if there's a 3G eater synthesis to replace the 4G synthesis used above, but I haven't tried looking with synth-const-4G-Python3.py, or just even just hunting for an appropriate kickback to produce the 2G recipe.

If I've counted correctly, these changes in specific should bring this oscillator down to 110G, and the gun to 94G.

Somehow I never considered making the blocks from 2G in a way that wasn't a 90 degree collision, since I automatically assumed the galaxies would get in the way...

This synthesis is a bit more granular than the first one pre-continuousifying since I often try to build multiple stationary objects at once as to try and prevent Catagolue from ignoring the fact that they're part of the same thing and incorrectly separating them. I also haven't tried optimising the galaxy side of things, which might cut down on some stuff.

[dvgrn]

Here's an improved synthesis with this brand-new information...

At least four of the eight eaters can be done with 3G instead of 4G, with just a kickback:

Code: Select all

x = 70, y = 94, rule = LifeHistory
$24.2A.6A$24.2A.6A$24.2A$24.2A5.2A15.C.C$24.2A5.2A15.2C8.C.C$24.2A5.

7$50.A$49.2A$49.A.A6$54.3A$54.A$55.A!

The other eater looks like it needs 4G, if I'm not mistaken, unless it can be built before the galaxies or the central blockers but that doesn't look too likely. Here are the 3G syntheses that synthesise-const-4G-Python3.py knows about, and none of them have gliders coming just from behind and two the sides of the eater:

I think the third and fourth galaxy recipes can be reduced from 12G to 11G in the same way as the first two, can't they?

As another excersize I tried creating the p552 glider relay also from DRH-oscillators. Getting the shuttles and blockers in the correct positions is a trivial task, but getting the glider inside is something I've been failing at for quite a while:

All of this probably allows for the construction of higher-period shuttles, but not the p552 version.

EDIT: Indeed, this allows for the construction of the following p2024 shuttle (I've included extra, redundant gliders to discourage Catagolue from erroneously separating components - if this goes through I'll attempt to remove them):

And just like that, we now have a synthesised p856 on Catagolue:

I managed to cut off four gliders via use of the 3G eater synth, and will investigate the galaxy reduction soon.

EDIT: It seems that kickbacks might still be necessary to build the galaxies, since from what I can see the existing galaxies would interfere with at least one glider:

With the aforementioned optimisations, this should now be 104G...

I wondered if there were other ways of building the galaxies -- and of course there are. Lots of them. So far I've only found more-expensive-than-11G ways,

But I only looked at the fifth line of C2_1 soups in Catagolue, third line from the bottom, and I could easily have missed a trick even among those. Seems like there ought to be something out there that makes two 180-degree-rotated things with 5G each and mashes them together.

[dvgrn]

As another excersize I tried creating the p552 glider relay also from DRH-oscillators. Getting the shuttles and blockers in the correct positions is a trivial task, but getting the glider inside is something I've been failing at for quite a while...

Here's a possible solution if you're desperate enough. There's probably something a little cheaper hiding in the categorized one-time turners from the octohash database, but this is a workable option partly borrowed from the 1G seed project for Raucci's p217. Luckily the longboatnboat constellation can be built before the shuttles, and even the boat in the boatnship combo could be constructed ahead of time with a slightly more expensive recipe for the second shuttle. There should be plenty of room to drop the ship in toward the end.

So this is not a complete synthesis, but it's a decent blueprint:

Also, here are some alternate pieces of 11G two-stage recipe for the galaxy, but while they have different problems from before, I think there's still an inevitable conflict with existing galaxies. Have you tried building all four galaxies simultaneously, though? I haven't dared look at that option with this new recipe.

EDIT: Aha, this just turned up in the s2g.col database, which I probably don't check often enough. There was exactly one result, just like the single result from 3g.col shown in the previous pattern. This must allow for some kind of clever workaround, no? (Again, haven't dared to look.)

There don't seem to be any lucky combinations of constellations, unfortunately -- the two possible hivenpond have known recipes but they're 4G, so that's worse than building the two beehives and then adding ponds. But at least there are several possible 2G ways to build the two ponds and still keep an 11G cost.

Bah, but you used a whole extra glider to shoot down one of the blocks to get the antiphased variant. That's simply not properly modern and civilized -- or do I mean "civilised"? Just not cricket, as we say in the U.S. in spite of having absolutely no idea how to play cricket.

(I went through all the likely shipnblock placements and found only 4G recipes. Was working through shipnbeehive and got a lucky recipe, but it was really probably more likely that a shipnblinker would have worked, so there's probably an alternate recipe or two out there.)

[muzik]

Here is my list of all the pentadecathlon pairs: https://conwaylife.com/ref/mniemiec/p15.htm#p15-pc. All can be trivially synthesized from 6-8 gliders, except one difficult one that Buckingham was able to synthesize from 14 (https://catagolue.appspot.com/object/xp ... 88ss/b3s23) although Catalogue now reports a 10 glider synthesis.

I've used this information to create a dedicated wiki page for pentadecathlon pairs, which should hopefully be easier for the community to maintain and keep up to date:
https://conwaylife.com/wiki/Polypentadecathlon

This should make all of the different variants as well as their costs and syntheses available at a glance. Currently I haven't listed the three pseudo-pairs, but a dedicated section for these will happen at some point. I also plan on creating some better images for the remaining pairs which are more consistent with the first five (visually, as well as in file size).

One very important thing to note is that through experimentation and looking through existing soup search results, I came across a total of five more non-trivially interacting pentadecathlon pairs that aren't listed on your site (refer to the entries with N/A in the Niemiec column). I've submitted syntheses to Catagolue for some - the rest should probably be trivial. The interactions between these definitely seem to be deeper than many of the others, with some only being valid pairs due to sheer luck.

For future reference, here are some things I had to look for myself in order to complete my recent oscillator syntheses:

LWSS + boat = glider, found manually using Seeds of Destruction. Definitely known already, but not in Niemiec's database for some reason. Used in the p143*2 Bandersnatch loop.

Putting together the base still life could probably be done automatically by transfer.py.

"very" reported a new bizarre 24-bit P2 in a soup on the Discord yesterday.
From the soup, I was able to develop a 19-glider Rube-Goldberg synthesis:

There are also the following stator variants, also 24 bits, that may be more difficult to synthesize:
