Thread for your unsure discoveries

[dvgrn]

So if we found more similar ones, would this one be added?

I wouldn't think so, unless it happened to solve some very specific timing problem better than any smaller constellation -- and we had some kind of huge database/lookup system set up so that we could look this up and know that it's the best answer to a given splitter problem, like

"Given input bo$2bo$3o! glider at (0,0) and splitter entirely in SE quadrant, produce output o$obo$2o! glider at (-3, 19, T=72) and output bo$2bo$3o! glider at (17, 7, T=145)"

We've done some surveys of two-object constellations to find splitters, but haven't even scratched the surface of three-object constellations. Starting a collection of four-object constellations just isn't in the works at the moment, since it would be a tough task to even enumerate the three-object splitters that might be useful.

For example, you can add a one-object turner in an unlimited number of locations, to any of the known two-object splitters -- plus there will be millions of "elementary" three-object constellations that don't break down into splitter+turner.

Is this (2,19) c/62 pi climber useful?
It's slightly dirty, it also produces a beehive every 62 generations.
I presume we can combine two or more climbers to produce gliders to clean up the beehives, and even more to make a waterbear-like spaceship.

Unfortunately those are a couple of very big presumptions. Oblique dirty fuses are a lot harder to work with than orthogonal ones, because you're stuck with just one orientation when you're rubbing pairs of fuses together.

It's not difficult to find a pair of these fuses where the left-hand fuse cleans up the right-hand fuse's beehive, for example --

-- but adding a fuse that way doesn't really improve anything: there's still a far-left beehive to clean up, just like before. It's going to be tricky to reach over to the far left and clean up the beehive on the leftmost fuse, let alone have optional output glider streams left over to do anything useful.

There are a lot of oblique fuses and crawlers like this, where the burden of proof is definitely still on the people who think that maybe there's a way to get an over-unity reaction out of them.

While playing around in Golly, I found what seems to be a gigantic P4 (?) oscillator. Is it something new/interesting?

That's a rather odd question. The only likely way to play around in Golly and produce this oscillator is to copy/paste it out of an existing larger pattern -- in this case, one of the many older period-52 gun variants.

With the two blocks taken out that make that p4 oscillator into a glider reflector, it's clearly a highly specialized sparker, but the sparks are all pointing uselessly into a nearly inaccessible chunk of empty space.

That makes it not particularly interesting, and the fact that it was copy/pasted means that it's certainly not new. How did you reach the point of posting it without knowing where it came from?

People around here tend to take a rather dim view of unclear claims of authorship, when it's clear that a pattern really came from somewhere else -- so please be more careful about attribution in the future.

[mniemiec]

Hi. I think i found a new oscillating pattern, as i have not seen it documented anywhere in the wiki. ...

There have been extensive manual and computer searches done over the years. Computer searches have found all period 1 patterns (still-lifes and pseudo-still-lifes) with populations up to 34, and period 2-3 patterns (oscillators and pseudo-oscillators) with populations up to 21. Higher-period oscillators and pseudo-oscillators up to around 21 has been comprehensively searched manually*, as well as spaceships up to the mid-30s*. If you find a pattern within those areas that isn't on the Wiki, it's likely that it's not considered noteworthy enough. E.g. the first few objects in each group may have their own pages (e.g. still-lifes up to 11 or 12 bits, period 2 oscillators up to 12 bits, etc.) but at larger populations, the number of objects becomes so large that keeping track of all of them (except in exhaustive pattern collections) becomes impractical.

(* Since manual searches are imperfect, it's not impossible that something new might come up; it's just fairly unlikely. E.g. the 20-bit Loafer spaceship was a fairly remarkable new discovery a few years ago, both for its unusual period, and its relatively small size.)

The problem is, it's almost impossible to get the B in (unless we find a conduit that sends the B back into itself, or a C-heptomino),but if we do find a way to do that using conduits, we might be able to double glider streams using this or use this as a sort of memory cell where the boat represents the state.

[hotdogPi]

Unfortunately, predecessors of B-heptominoes pretty much always move forward, so pretty much anything will hit the boat.

Unfortunately, predecessors of B-heptominoes pretty much always move forward, so pretty much anything will hit the boat.

You're right about that , but that's why I mentioned the C-heptomino because I often see its predecessors come backwards in random configurations, so it might solve our problem (if we can find a conduit that outputs a C, of course)

No need to be unsure about this kind of thing I'd say -- a synthesis isn't Really Known these days until Catagolue knows it, and Catagolue thinks that that still life costs 104 gliders, as you said.

It's maybe worth noting that Catagolue nowadays includes a lot of extraordinarily suboptimal recipes. Whenever a transfer.py run against still-lifes-with-soups turns out to be able to build a still life in any way at all, that recipe will get added to the database. It's not like transfer.py is making any attempt to analyze the soups in question and see what hints they provide -- that's still a humans-only activity for the moment.

I think the current estimate is that there are hundreds of thousands of Catagolue recipes, maybe more like a million, where the odds are good that the synthesis can be improved by some synth-expert human looking at soups and figuring out a better approach than what transfer.py came up with.

This is one of several reasons why it it would be good if Catagolue had some kind of "source" attribute, to make it possible to label syntheses so that it's easier to tell where they came from. It would probably be too risky, inevitably getting misused and/or starting silly arguments, so I doubt such a thing will ever get implemented, but it would be nice.
