Synthesis challenges

[MathAndCode]

The goal of this thread is to create syntheses for various still lives and oscillators. You are only allowed to use the two-glider collisions (and not any two-glider syntheses for the object in question if it only costs two-gliders), reactions that you discovered or independently discovered, and miscellaneous reactions not immediately relevant to glider syntheses. For example, here is a synthesis of a ship that I made using one of the two-glider collisions that makes a domino spark that doesn't die right away:

Code: Select all

x = 23, y = 13, rule = B3/S23
17bo$obo13bo$b2o13b3o$bo6$21bo$4b3o13b2o$6bo13bobo$5bo!

Cost does not matter; instead, the first person to synthesize the object gets to choose the next object for others to synthesize as long as the object isn't too difficult to synthesize. The first object to synthesize shall be the pond.

Does this count?

Yes (although you could have used the two-glider collision for a blinker). Now you get to choose the next object to synthesize.

SOrry for being late.
The next one may be xs8_33w33

EDIT: Could you show me my previous synthesis in the testing thread? My post disappeared.

xs24_g8kidik8gz0124b421 just stirred up some interest on Discord. Dumping all the soups out to a big RLE file turned up quite a few exceptions to the general rule that this still life appears within the first few ticks. The full collection of 602 soups is attached.

602-xs24-soups.rle

Should be pretty quick to sort out the few promising ones from this collection -- they're the ones where you can't see xs24_g8kidik8gz0124b421 in the middle after running a dozen ticks...!

EDIT: This 26G recipe is what will be on Catagolue unless someone can find a soup with something extra promising in it, that I didn't notice on a quick scan:

Code: Select all

x = 305, y = 87, rule = B3/S23

There was an occasional really cool soup in the collection. My favorite was this one:

I posted a synthesis in your thread before, and now it vanished.
My pi day thread, my esolangs thread, my glider destruction thread had all disappeared.

The goal of this thread is to create syntheses for various still lives and oscillators. [...]

It might be a good idea to put glider synthesis target suggestion ideas in a separate thread, to avoid cluttering the actual synthesis threads. (Suggesting something is often low-effort compared to doing it.)

Here are several big catalysts/catalyst variants from glider-consuming stable components:

How many of p5 oscillators in b3s23osc_stdin/xp5 can be constructed by colliding gliders?

Another similar "glider synthesis challenge" (?) might be to find glider constructions for all catalyst variants that were used in some mechanism (oscillator, gun, reflector, conduit, factory, two components welded to each other) that was posted.

how in the world of conway is this a still life.

apgcode xs30_rr0v92sgz660743, apparently no known glider synthesis, apparently no soups or other sample seeds of any kind so far, glider synthesis challenge 660743 air molecules

The still life xs26_4a9b8bqiczca23 had a known synthesis at least since 2022-07-05.
There seems to be no easy way to add the block, to construct the "diehard" still life (xs30_354cwmmz65139d543)?

Code: Select all

x = 16, y = 10, rule = B3/S23

Is it even possible to get a block in from that starting still life? My quick looking at it says we need to turn on the blue cell, the red cell can't be on because it destroys the eater, so we need the white cells, but those also go and interact with the rest of the still life.

Code: Select all

x = 20, y = 16, rule = LifeHistory

Edit:
xs30_0mm0e96z345d1d952 has a synthesis which has the block in place but a bun in place of the eater - any way to get from it to the desired one?
