Soup-based syntheses

[Freywa]

Goldtiger997, BlinkerSpawn, me and a few others have found out that Catagolue's sample soups are a gold mine for developing or improving syntheses. I ended up making many edits to one post in the Synthesising Oscillators thread detailing examples of such syntheses.

Since the soup search results thread is not dedicated to syntheses, this thread will be. To start off, here's Scot's p5 in 27 gliders from this soup:

Code: Select all

x = 280, y = 147, rule = B3/S23

Any new or improved synthesis I know of will eventually make its way into Shinjuku, so you may want to keep an eye on it from time to time.

Here's a synthesis helpsheet for those who want to assemble their own syntheses. The number above each collision is the number of generations needed to get from the live cells to the marked cells:

I would not prefer to have tentatives and partials of syntheses. I want full syntheses, and high-quality ones at that.

Using the spanking new findpreds.py, hat siamese loaf in 6 gliders (was 12). This still life appears on the path to rattlesnake, reducing the latter's cost to 31 (and thus below the reverse caber-tosser limit):

I'm new to the synthesis game, but I thought I'd have a go at a random unsynthesised (in Shinjuku) 18-bit SL.

I first saw it as the result of a 4G collision:

Code: Select all

x = 19, y = 14, rule = B3/S23
2bo$obo$b2o4$8bo$6bobo2bo$7b2o2bobo$11b2o2$16b3o$16bo$17bo!

Some methods of constructing it were posted on the Soup search results thread, but I don't think anyone completed the synthesis. This synthesis comes from https://catagolue.appspot.com/hashsoup/ ... 1478/b3s23
