How to flip the snake to obtain xs20_255q8ie0mq?

My xs20 for today is the lovely xs20_4s39mkiczw121.

Is it known to be easy to spark a mango to kill one of the cells at its pointy ends, as in the sample at right below? I'd like to give the mango another job:

Code: Select all

x = 59, y = 17, rule = B3/S23
2o4bo43b2o$2o3bobo42b2o3b3o$5bobo47b3o$6bo$51bo$4b2o45b2ob2o$6bo43b4o

48b2o!
Tomorrow's xs20 is xs20_8o6hraicz23.
I'll have to decide between this option, where I don't know yet how to create the Thing By The Pond --

Code: Select all

x = 25, y = 18, rule = B3/S23
15b2o$14bo2bo$14bo2bo$15b2o$11b2o$10bo2bo$bo10b3o6b2o$obo17bo2bo$b2o
18bob2o$22b2o7$11b2o$11b2o!
-- and this option, where the only thing I don't know is how horribly expensive it will be to clean up:

Code: Select all

x = 16, y = 24, rule = B3/S23
2bo7bo$2bo7bo$2bo7bo6$2obo$b3o$2bo4$4b2o$4bobo$5bo2$13bo$13bobo$13b3o$
11bo$11bo$11bo!
EDIT: It's tomorrow now! The second one squeaks in under the wire at 19G, without me even having to try hard... so nobody has to worry about the Thing By The Pond unless they want to:

Code: Select all

x = 178, y = 88, rule = B3/S23

Here's a method:

Code: Select all

x = 9, y = 7, rule = B3/S23
o$b2o$2o3b2o$4bo2bo$2o3bo2bo$b2o3b2o$o!
It requires the block to be placed afterwards.



Edit:

Code: Select all

x = 49, y = 59, rule = B3/S23
41bo$41bobo$41b2o$2bo$obo$b2o42bo$43b2o$44b2o$2bo$3bo$b3o18$24b2o$23b

3bo$2bo22b2o$24bobo$26bo4$7b2o$6bobo$8bo!
There's probably a cheaper way to synthesize that beehive predecessor at the bottom, which would prevent having to clean up the block at the bottom.
I have reduced the cost of universal construction to seventeen gliders and probably to sixteen. All that remains is for the universal operations to be found.

If you're unsure about whether a constellation has a three-glider synthesis, you can simply find the constellation's apgcode then go to its Catagolue page. In this particular case, Catagolue has a three-glider synthesis.

Code: Select all

x = 14, y = 7, rule = B3/S23

That means that the still-life can indeed be constructed with nine gliders.
I have reduced the cost of universal construction to seventeen gliders and probably to sixteen. All that remains is for the universal operations to be found.

At least 7 3-Glider collisions produce that particular Blinker+Block. Here's the fastest one:

You can actually skip the constellation and get the starting reaction from 3 gliders. The cleanup only needs 1 glider for a total cost of 7:

Code: Select all

x = 44, y = 70, rule = B3/S23

Is that not 15G, instead of 16G? The glider and pattern shown in the middle step is duplicated in the last step, and the initial blinker comes from 2G.

Looks like Catagolue has figured it out, more or less -- it just threw away the middle stage. Probably better that way, anyway -- there's probably not a whole lot of point in deconstructing the cleanup into four separate stages, since there's no doubt a cleverer way to do the cleanup, or this whole construction.

This is sort of soup-mimicking and sort of not. It's inspired by the last two generations or so of this still life's two soups, but has to be constructed with very synthetic methods.

Octohash works well with the B-like decomino thing on the right!
By the way, is there any python3-compatible version of synthesise-constellation.py that I'm missing?

For some reason, I thought that octohash didn't include long boats.



Edit: One of the blocks can be replaced with a glider.

I have reduced the cost of universal construction to seventeen gliders and probably to sixteen. All that remains is for the universal operations to be found.

Yeah, I checked in a Python3 version here a couple of weeks ago, for wildmyron's improved version of the database (duplicates removed, and a subset of 4G collisions added).

xs20_ci9riiczw66 477...
Really, everybody has been ignoring xs20_ci9riiczw66, with more than a thousand soups to choose from?

I just checked out the 2x128 soup and the first half of the 64x4 soups, and came up with an uninspired 15G recipe:

248b2o$248bobo!
I'm sure that many possible improvements lurk out there in the remaining sea of options, but 15 is less than 18 so I'm not inspired to go swimming in the soup.

EDIT: Aaaand the next day's quick-and-dirty 15G synthesis is for the xs20_ci9riiczw66, from the fourth 4x64 soup -- again, didn't even look at the other four hundred seventy-odd soups below that:

Code: Select all

4bo$32bo$26b2o$25bobo$27bo12$2o$b2o$o!
EDIT2: The next day, I didn't get past the very first 2x128 option for xs20_ciq32arzx311 to look at any of the remaining 345 soups.

The octohash database and synthesise-patt quickly produced an 11-glider synthesis, from which I would guess that there's a recipe with a single-digit number of gliders out there waiting to be found.

Code: Select all

x = 194, y = 37, rule = B3/S23

EDIT3: Another day, another xs20 synth. The 8x32 soups for xs20_g0bq2kozd543 all create the object in the first few ticks, but after looking through just the first couple of G1 soups, a nice easy 11G synthesis turned up again, so I didn't even taste-test the remaining 330-plus soups.

Code: Select all

x = 178, y = 56, rule = B3/S23

A throwback final step, the kind that we had before the advent of spark_search:

Code: Select all

x = 30, y = 30, rule = B3/S23

It's based on the predecessor in the second soup, but not the actual reaction that makes it, per se.

Trivial improvement to the initial constellation from 8G to 7G by actually bothering to use a 3G object-pair synthesis:

Still, 19 gliders is good enough to squeak in under the <1 glider per bit limit.

Two 3G object pair syntheses are better than one, and the total cost can be reduced to 16 with more efficient cleanup:

x = 304, y = 84, rule = B3/S23

EDIT: Yikes, some transfer-ing has been going on behind the scenes: xs20_8kiabaiczx311, which was on the no-synth-lotsa-soups list, now has an 87-glider recipe.

With over three hundred soups to choose from, we can do a good bit better than that... The first ten G1 soups have several approaches that seem workable. Here's 13G as an upper bound:

But can someone remind me how to retrieve the glider collision from the Mateon1_Glider6_5_6_Test soup?
