This catalyst is boring for what it does, but it's funky-looking and implodes sharply (gen 11-13) while doing its thing:

Pi flips a bi-ship (perhaps a bi-ship hassler could be made from this):

Pi pushes two boats, but unfortunately leaves behind some blocks:

Pi, teardrop and boat produce eater2:

[wildmyron]

I don't explore B3/S23 much but inspired by the edgy pi predecessor posted elsewhere I ran a search for similar patterns. B + R -> edgy Pi:

Code: Select all

x = 16, y = 23, rule = LifeHistory

Almost certainly useless.

It's trivially equivalent to one of the previously posted pulsar seeds that involves a pond, but instead of a pond, uses an easier boat. Nice find!

With the 2SL B60 seed, is it possible to make a slow-salvo recipe for Michael Simkin's glider gun with a reasonable amount of gliders?

With the 2SL B60 seed, is it possible to make a slow-salvo recipe for Michael Simkin's glider gun with a reasonable amount of gliders?

Fairly reasonable as these things go, but it will still take quite a few gliders to complete a recipe. You're only saving one still life over just building the blocks directly, and you can often build two blocks simultaneously. So for some orientations it may not actually end up being cheaper to use this (admittedly very impressive) conversion reaction.

On another note, a small G-to-G8 splitter...
I'm looking for small G-to-Gn splitters similar to this one.

There are an incredibly large number of these, especially if you allow up to three still lifes. Quite a few of them are scattered through simsim314's 2sL splitters, for example, if you want to sort them out. A labeled stamp collection might be useful. Seems like there are too many for it to make sense to post one at a time.

I have a vague memory of an existing stamp collection from a few years ago, of splitters that produce multiple gliders in the same direction. It might take some detective work to find it again. Might have been chris_c or oblique, in a discussion either about the half-baked knightship or the 31c/240 Caterpillar -- I don't think it was as recent as simsim314's engineless Caterpillar.

One line of exploration involved running searches to produce two gliders with exactly the right relative timings and lanes. The idea was to start with a seed that needed two gliders to activate it, and convert it to a 1G seed. Might have been *WSS edge-shooter seeds -- I remember it turned out to be easier than I thought to find good solutions.

Another research project that I think turned up some G-to-G(n) results was an early investigation into glider turners and splitters with different timings, probably made as cheaply as possible with slow-salvo gliders starting from a block. (?) Can anyone find a link that matches either of these?

[gmc_nxtman]

Nice, but a little messy -- Gustavo cleaned it up for you with another block.

Clean LWSS seeds can be made with just three blocks. There are various clean 2sL *WSS seeds.

You'll find a lot more of this kind of thing if you dig around on the 31c/240-spaceship or engineless-Caterpillar threads. At least for building self-supporting spaceships, *WSS seeds are most useful if they're edge shooters -- there's a useful one based on a boat and a block (the "champion"), and an HWSS edge-shooter in the same post based on a blinker and eater.

I used it to find this 9-glider destruction of a Big-S:

But if you remove the gliders in a particular order, you get a clean 8-glider destruction, a clean 7 glider destruction, etc. all the way down to a one glider destruction.

[mniemiec]

I just modified my script (which I mentioned elsewhere) that searches for a single-glider destruction of a given pattern. If any key is pressed during searching, the collision resulting in the smallest bounding box is displayed.

Why not just first check for a single-glider destructor, before doing anything more complicated? Most still-lifes can be destroyed with a single glider, and most that can't, can still be turned into a simpler (e.g. a block) one that can be destroyed with a single glider. An object that fits into an m*n bounding box has at most m+n+8 possible glider lanes intersecting it, so 4p(m+n+8) (for a period-p object) should do it (or less if it possesses symmetry).

If a single glider can destroy it, or turn it into something easily destroyable by a second glider, you have a minimum 1- or 2-glider destructor. Otherwise, you could also try one of 4p(m+n+8) LWSS collisions, or 4(m+n+10) MWSS or HWSS collisions. These can be done by a script, but are also simple enough to be done by hand. Only if all of these fail do you need to resort to a script that can place multiple gliders or spaceships. (Granted, your script could find a 2-glider destructor that is better than a single spaceship.)

The domino sparks that it gives off are useful for destroying gliders.

This thread (and every other thread in the Patterns subforum) is for patterns in B3/S23 exclusively. There are threads in the Other Cellular Automata subforum where discussion of that rule and that oscillator can be done, but not here.

Why not just first check for a single-glider destructor, before doing anything more complicated? Most still-lifes can be destroyed with a single glider, and most that can't, can still be turned into a simpler (e.g. a block) one that can be destroyed with a single glider.

That's what this script does. The script is supposed to be run until it finds a clean single-glider destruction, or until you are convinced there is no such destruction, in which case you can quit and see which collision ends in the smallest bounding box. Then you run the script again to see if the resulting pattern can be destroyed by a second glider, and repeat until you have a clean destruction.
