Down to 64.

@Freywa: please can you accept merge request 38, containing Alex Greason's collisrc+transfer results? There are plenty of new efficient xs17 syntheses in there, so it might get us significantly further through the project: https://gitlab.com/parclytaxel/Shinjuku ... equests/38

To moderate expectations, if I recall correctly only two expensive xs17 were reduced by that, and I submitted them both separately anyway so they're already in catagolue.

And to clarify what that was, it wasn't from combining collisearch and transfer, that was just running transfer.py. The only difference is that I ran it targeting everything in catagolue rather than "just the xs17" or the suchlike.

The three still lifes and the 3G collision to make the junk in the lower left are inconveniently arranged, so I couldn't figure out a solution with constellations, but one probably exists. If anyone cares to try to reduce it, the boat can be replaced with a ship, and that variant likely has a 1G cleanup--you could start from there.

A route that might drastically reduce #s 7-10 if it can be completed:

The leftmost spark is the most complicated, but also more versatile than the above suggests; all that's needed is a dot spark that persists for a generation with sufficiently dense junk behind it to kill the unwanted part of the reaction. It probably won't solve any of them completely, since xs13_6246pic costs 7G and equivalents of the other two sparks cost likely 3G each, and I doubt the challenging spark can be made in 3G.

Semi-related: AGreason's collisrc and transfer.py runs improved a bunch of 15-bit still lifes. Since then, I've been chipping away at the remainder that cost 13 gliders. Today, Goldtiger improved the difficult final four over on the Discord, so all 15-bit still lifes now cost 12 gliders or less.

Ouch, these remaining cases are getting difficult. A number of the remaining syntheses take multiple stages to do conversions that look like they "ought" to be done in a single stage -- like the three-stage 9G preblock to tail in #5, xs17_039s0qmz311, for example.

That one will have to be manually committed through Shinjuku rather than Catagolue's submission box, I think, due to the separation between gliders. And these last few are indeed tough, which is partly why I moseyed on over to the xs15s for a while.

Inserting the following sparks at generation 29 would solve #168, and if done cheaply, possibly #3 by converter. There are plenty of ways to make the upper left spark, but they all leave the cell in yellow has to remain off until the insertion is complete, so, probably a variant on an edgy toad synthesis is called for.

That one will have to be manually committed through Shinjuku rather than Catagolue's submission box, I think, due to the separation between gliders.

This seems like it must be a solvable problem. How about an optional second textbox on Catagolue's submission page, defaulting to a minimum separation of 20 cells? In cases like this where larger spacing is needed, we could submit something like

Code: Select all

x = 359, y = 163, rule = Life

and type in "80" for the minimum number of blank columns between stages. The recipe has a maximum of 70 blank columns between objects within a stage, but 100 blank columns between stages, so presumably with an extra "80" hint the recipe could be parsed correctly.

(?)

This seems like it must be a solvable problem.

The problem is that I've already committed it myself.

EDIT 5: #156 in 15G, partly based on an improvement to a base still life by removing two gliders that didn't actually perturb the Herschel--they actually hit where a spark would form such that it wasn't obvious that the Herschel was unaffected.

EDIT 6: #71 in 12G from soup; onerous cleanup likely improvable. #210 probably follows via converter, but I don't see it in my few files. Someone run transfer.py on this, please.
