Catalyzed collisions of a glider with common bait still lifes

[Kazyan]

See title. This is the result of a series of CatForce runs a few years ago, in which a glider passes by (or directly strikes) a bait still life. This mess of folders is what revealed the reaction for the bumper, plus a couple of still life factories. It was originally intended as part of a two-part project: first, create a database of collisions where a glider, plus catalysts, could transform bait still life W into signal X, offset by coordinates (Y,Z), and possibly with some other junk or gliders flying around. Then, dig through CatTorce results on a Herschel, B-heptomino, century, etc. to create a database of reverse transformations: signal X to still life W, offset by coordinates (Y,Z) and possibly with some other junk or gliders flying around. Finally, compare those databases to see if there are any matches.

This project never happened. It's also not up-to-date with new generally-applicable catalysts: for the most part, it only used spartan objects as catalysts, plus the spartan TWIT alternative.

Due to size constrains, I'm uploading the mess of folders in a Google Drive. Also, I'm excluding the results for the following three collisions, because they were huge:

Code: Select all

x = 44, y = 8, rule = B3/S23

This is quite a project! I just barely started to look at these and immediately got distracted by an interesting pi catalyst which proved to involve a transparent ship. I messed around with it some more, and found this amusing, if useless, device:

The sheer number of results here is incredible. I assume you've done thorough filtering to find all instances where the bait SL is restored? (Also, you wouldn't happen to have a file containing specifically those patterns, would you?)

Honestly, I wouldn't know where to start trying to sort through these results — there's probably more potential G-to-X search space alone hinted at in here than anyone could (at least manually) investigate in a lifetime.

(Just for fun, another amusing but useless device:)

Code: Select all

IIRC, I visually looked through all of the results that weren't just walls of hundreds of versions of an explosion (like the three excluded collisions), but I don't recall any bait restorations that haven't already been shared. But if you do find something cool in there, do share!

For a start, I suppose you could just go through the Block, Beehive, and Blink folders, since those baits are the most likely to be restored. Pick something that leaves an active region at the edge of the bounding box after the catalysts do their thing, then hit it with your programs of choice. The "Useful-Transforms", "2cat-collect", and "!AllCollect" files contain results that looked particularly interesting to me at the time--mostly, objects that are changed but don't move far from their original location, but also with other shinies.

In addition to the things you mentioned, I'm finding quite a few leads on possible new pi conduits in here — here's an example:

Code: Select all

x = 37, y = 32, rule = LifeHistory
11.B$10.3D$10.BDB$9.3D2B$9.5B$8.6B$8.6B$9.5B$9.6B$8.6B3.4B4.2A$8.14B.

11B3.5B$4B9.B2.3B5.3B!

It would be a Pi-to-H if not for an annoying beehive for which there's no easy cleanup (not even a rectifier works). There are many more options for this particular transparent boat reaction I haven't tried yet, so I don't doubt there's a conduit to be had with the right combination of catalysts. And again, I've only really scratched the surface of the set of reactions contained within your database — so there's probably quite a bit of low-hanging fruit available for anyone who wants to look.

kk, did not know that one, I suppose it is part of the list of eaters/still-life the search uses too, explaining it's occurence. Well there is a few interesting things but finding something ground breaking is not trivial.
