It's totally NOT p26.

Why not? Those seem to be p26 glider streams. It's a little confusing, because the phase-shifting reaction also moves the queen bee shuttle one cell away from where it would naturally show up again after 30 ticks -- but doing the phase shift on the other side after 13 ticks shifts the shuttle back to the right place again.

Eater2s can't supply the sacrificial blocks, it seems. Maybe Bellman can come up with something, I suppose -- I haven't developed any intuition yet as to which problems are likely to be solvable and which are still ridiculously unlikely. My uneducated guess is that this tends toward the "not very likely" side of things...?

[Sphenocorona]

You'd have to find something which recovered its points of contact with the QB in exactly 26 generations, as the blocks would have interacted before the phase shift could happen.

[Scorbie]

@dvgrn
Agreed. On second thoughts it would have been better if this was on useless discoveries thread.

@Sphenocorona
I thought of a different reaction with the same result. If there is a catalyst that makes

Code: Select all

to

Code: Select all

..o

Then it's okay, although this seems as unlikely.

EDIT: this search came out with no solutions (pretty quickly, by the way,) which probably means that there is no likely such p1 catalyst, right?
Incidentally, the search crashes without the filter but ends peacefully with the filter.

Very pretty, but it's just a curio involving the cancellation of many T's.

Is there any way to compile a list of simple transparent-object collisions to aid programs like catgl/etc? Rather than take on the bulky task of searching for transparent objects to suit a given reaction, we could have a bank of "this object is transparent with regard to this junk" entries, and maybe it will be a hit often enough to be useful? Looking at the rectifier, for example, two of the catalysts involved are eaten and rebuilt, and if there was a way to use the information about those and related processes to help other search programs it would likely pay off.

[dvgrn]

Is there any way to compile a list of simple transparent-object collisions to aid programs like catgl/etc?

It's a good thought, and it might possibly work. In a sense we already have something like that: Calcyman's collection of known working converters has stuff like the old standard B-plus-transparent-block-plus-helper-snake -> clean output Herschel, and getting more complicated from there. There's definitely no problem adding more transparent-object-based converters to those lists.

On the other hand, the reaction you posted seems to be more of a transparent eater, or absorber -- like the transparent beehive that can stop up the end of a Herschel conduit. I'm sure there are a lot of reactions along these lines, but finding Herschel conduits is primarily a problem of guiding a reaction to continue to a new location, not making it stop. So I'm not sure whether it will help very much to keep a big list of that particular kind of transparent reaction. If you ever needed the transparent beehive, for example, you've basically already solved your problem and have a new Herschel conduit...

Now, there are a lot of other useful transparent beehives. For example, there's a 28-tick R-to-B in one of the H-to-G converters, a beehive+block combination that drops a glider on the other side of the beehive. Now that one is really useful:

It doesn't seem to be included in Calcyman's current converter collection, unless I'm missing it somehow -- probably because it's usually a period doubler (dropping that extra block) instead of a clean conduit. It can be cleaned up easily with a Snark assist, though, and it converts to a clean H-to-G... come to think of it, with enough of a Snark assist it turns into a slow but surprisingly high-clearance R-to-B converter. For Use Only In Extreme Emergencies, I guess:

EDIT: I probably should have given this example instead -- it recovers a lot faster, and lets another glider escape. This is actually a new record R-to-B in terms of clearance on that side -- no live cells within four rows of the R. Only the boat R-to-B does that well, and it's on the other side where there usually isn't room for it.

At the moment I'm just pointlessly rebuilding the L156, though -- are there any connection problems that this thing actually solves?

Anyway, the point is... well, I'm not sure I had a point, but I get the feeling that these kinds of reactions tend to be horribly contingent on the details of the incoming reaction, so that if you try to match them up with new unknown reactions, 99.9% of the time something will go horribly wrong. Like that extra block that shows up in the above reaction, where you don't see that with the standard L156.

-- Maybe the remaining 0.1% is good enough to make it worth compiling the table of transparent reactions, but there's a lot of frustration waiting there. So for now I think I'll stick with my time-tested Herschel-conduit research methods (that don't work very well either...)

...
A sacrificial block turns a B-heptomino into a bookend, which then restores the block during its normal evolution cycle.

That certainly looks like a non-trivial transparent object to me. The active reaction starts out on one side of the block, and after a while the reaction has moved a good distance to the other side of the block, and the block is back in position with no leftover junk back behind it.

That said... we don't actually seem to have any known ways to use that resulting century (bookend). We can put together something like this, but it's pretty messy. It seems we need a Magic Toad-Banishing Device in the northeast somewhere, because the previous reaction envelope doesn't allow access from the west:

I tried saying the magic words several times ("Someone should run a Bellman search on this! Bellman, Bellman, please bring me the perfect catalyst!") but unfortunately nothing has happened so far. I forget if I'm supposed to put something under my pillow now, or wait for Christmas, or both.

There are only about a dozen ticks between the restoration of the block and the appearance of all that leftover ash, so really another transparent object might be needed to lead the reaction further... but then we'll be right back where we started, of course, looking for a clean output.

Could be another thing to try in a catalyst search, replacing a block in very rare cases. Normally it will work just like a block -- but the double eater produces a symmetrical spark, which might sometimes affect the remaining active reaction differently from the asymmetrical spark that a block throws off to one side or the other.

Seems to me people must have tried this as a stabilization of a queen-bee shuttle, probably way back several decades ago. Now it might just be another specialized tool for the catalyst toolbox -- which thanks to Bellman is just about overflowing these days...!
