18-bit SL Syntheses (100% Complete!)

[Freywa]

Another unreasonable number appears to be the 930 currently unsynthesized xs19s.

If anything, that is the next goal I want done. You have unlimited gliders for this "19-in-any" project, so the pressure should be much less than in any fixed-glider challenge.

And I have made a thread for it.

I don't know if this is the proper place, but I have reduced the 20th most expensive 18-bitter from 48 to 12, making this my second ever CGoL synthesis. I also don't know if this is the right place to post it but here you go:

Code: Select all

I don't know how to submit to the catagolue box and I have to go to bed, I would politely request someone submit it and direct me to the necessary programs.

EDIT: better view of the continuous synth:

Code: Select all

x = 68, y = 57, rule = B3/S23

It literally just requires copying this RLE, pasting it in the box at the bottom of https://catagolue.appspot.com/syntheses and pressing Post.

The idea of the box was to allow people to submit syntheses without needing to mess around with the internals of Shinjuku.

A factor of four is quite an improvement -- congratulations!

The fabulously nonmagical box also accepts incremental syntheses. According to this discussion on Discord it might be pretty simple to get Catagolue to prefer a multi-stage synthesis to a single-stage one --

that second one is mostly a matter of setting "prefer_longest=True" in wherever the shinjuku dijkstra() call is
it's already a parameter that exists

-- but for right now whichever one gets in first will get stuck in the database. So I've gone ahead and submitted the following in hopes it will get in ahead of the other one, since continuous syntheses kind of obfuscate the stage information:

Code: Select all

x = 109, y = 25, rule = B3/S23
15bo57bo21bo$14bobo57b2o2bobo13bobo$14b2o57b2o4b2o13b2o$79bo2$bo78b2o$
o80b2o$3o77bo$100bo$b3o95b2o$3bo81b2o12bobo4b3o$2bo81bobo19bo$85bo21bo
$5bo$4b2o$4bobo86b2o$92b2o$94bo5$94b2o$94bobo$94bo!

Those are the individual stages that Catagolue doesn't already know about yet, with at least 20 blank cells between the groups. The system doesn't mind duplication, it just discards what it doesn't need. But some of the stages were a little too close to each other. Now it's just a matter of waiting up-to-eight hours for the next automatic update.

It makes some 18 bit SLs significantly cheaper so I guess this is a new component:

Code: Select all

x = 52, y = 54, rule = B3/S23

The bottom half is taken from the previous best synthesis. The top half is my own.
