I can't find a relevant topic for these small-period discoveries, and they aren't worth their own topic, so I'm posting it here.
Some low-period oscs:

Code: Select all

#C 1: a known p3 wick (left) and its variations (right)
#C 2: Seemingly new p4 (left) and and its agar form (right)
#C 3: A known p3 (left) which can be made into a wick (right)
#C 4: A small billiard table found in randomagar, which is probably known.
#C 5: A p6 also found in randomagar.

EDIT: here's a list of 1) new wicks and 2) almost oscillators. p4-13, p5-7, p5-9, p6-6 (using known wicks), p6-10, p6-20, p6-28, p6-41, p6-42 looks really likely to stabilize, so I recommend you to pick up these low-hanging fruit.

I'm not sure if any of these oscillators have been discovered yet. They've probably been seen before.

Here they are:

EDIT:

Found these using a search program that gives you low-period oscillators. P2 oscillators and still lives come quickly, P3 is a bit slow, and P4 and above can take an eternity. ESPECIALLY with the higher periods.

I'm not sure if any of these oscillators have been discovered yet. They've probably been seen before.

Sorry to tell you that p2 and p3s are really really diverse so most of them don't get attention unless it has an interesting property. (like catalysis...) And I think most of the componenets of p2 are pretty much known. But over oscillators over p7 get attention, I think.

Found these using a search program that gives you low-period oscillators. P2 oscillators and still lives come quickly, P3 is a bit slow, and P4 and above can take an eternity. ESPECIALLY with the higher periods.

Did you use your own search program??? I'm very interested on how it works. Well it usually takes a lot of time to find something unique in Life. Finding new oscillators (with a special property) usually takes hours or days.

Ahh, JavaLifeSearch. Great utility with nice user interface and a lot of options. There's also WLS which is faster but has a slightly clunkier user interface compared to JLS, in my opinion. A lot of searches have been done with those kind of utilities, so I won't be looking forward to find something new with general searches. There are still some specific searches which, I think, is in the range (more like the boundaries) of current searching utilities. The most I'm looking forward to is a p7 domino sparker. (I've seen quite some situations needing that, but I forgot except for Jason Summers' p28 wick)

The p8 was already known, but the p9 is new, although I doubt it would be any more useful than the following p9 domino sparker:

What properties make for a good sparker?

There are the obvious properties: isolated sparks, good clearance around the edges, and a small bounding box. Of course, the true mark of a sparker's usefulness is its ability to do something no other known sparker can do. At periods 8 and above, sparkers are difficult to find, so we sort of have to take what we can get.

If you're successfully running searches for p9 objects, then you're maybe getting almost within reach of an interesting search frontier.

At p11 and above, I think it might be technically theoretically possible to reflect a glider directly with an unsupported oscillator that makes a diagonal spark:

Code: Select all

x = 6, y = 6, rule = LifeHistory
3.A$3.A.A$3.2A$BC$2BC$3B!

Once upon a time I would have said that a big potential use for a pN domino sparker would be to assist in a color-changing glider reflection:

Code: Select all

x = 21, y = 24, rule = LifeHistory
3B14.4B$4B12.4B$.4B10.4B$2.4B8.4B$3.4B6.4B$4.4B4.4B$5.3BA2.4B$6.3BA4B
$7.3A3B$6.7B$6.7B$5.2A7B$5.2A.B2A2B$8.BABA.B$9.BAB.2A$7.4B2.3B$7.2A2.
A3BA$8.A2.A4BA$5.3A4.BABA.A$5.A8.A.ABAB$15.A4BA$16.A3BA$16.3B$17.2A!

These days that's only true up to a point. We still don't have a color-changing Snark-sized reflector, but we can build one that isn't too horribly big, out of a syringe plus the right H-to-G. So domino sparkers are only useful for that up to a certain size (and known p9s are very far from having enough clearance.)

There are other small sparks like

Code: Select all

x = 7, y = 5, rule = LifeHistory
2.A$A.A$.2A$4.2C$6.C!

that can turn a glider, but it looks like they would probably need a higher period than p11 to repeat cleanly.

Now, if period N+1 is generally maybe an order of magnitude more CPU-intensive to search than period N, then we probably aren't really very close to period-11 searches yet. So searching for oscillators with most unassisted glider-turning sparks still needs some new clever tricks, before it will become practical... and it's a very very long way to period 14, where we could search for a direct period-14 glider gun.

[mniemiec]

At p11 and above, I think it might be technically theoretically possible to reflect a glider directly with an unsupported oscillator that makes a diagonal spark: ...

A p10 thumb spark should be able to do this.

[HartmutHolzwart]

I believe this is a new c/5. We're still short in them, especially in unsymmetric ones.

[Sphenocorona]

The back pre-block & pre-hive configuration is not critical to the rest if the ship - it is a tagalong. The back end is about as sparky on back and sides as a spider. Maybe it could be used in a more compact trailing edge for c/5 greyships?

[Scorbie]

I think bullet51 is refferring to the p10 tagalong, rather than the whole ship. I think I have seen the p5 components at the front in jslife and other places, but have never seen the p10 part. So I guess it is a new discovery!

[Bullet51]

I think bullet51 is refferring to the p10 tagalong.

Exactly!

I believe this is a new c/5.

It's already known, since it is found in jslife.

I wonder if a Bellman catalyst could shove the honeyfarm's top beehive back down one cell.

Code: Select all

x = 31, y = 20, rule = B3/S23

$27bo$26b2o!

Failing that, the output could be made to do something like this:

Code: Select all

x = 21, y = 14, rule = LifeHistory

$3.2C7.3D3.2A$3.C!

Don't know if that would beat 1223 ticks, though.

A stable beehive pusher would also be nice, although it couldn't be used here because of the way the HF forms - a pentadecathlon can't be used either.

Speaking of near-transparent HWSS reactions, I find this one interesting - nothing new, of course.

Code: Select all

x = 13, y = 5, rule = B3/S23

Edit: Unrelated - are there any p24 sparkers, or a glider collision that produces a one- or two-cell spark and works at p24?

Code: Select all

Managed to get an HWSS-G that works at 638(?) ticks. Could be substantially improved. (I hope I didn't screw up this time)

2o! 

EDIT (7:51 EST):
Just discovered this can eat stuff. Because it has 4 corners, and the part that eats things are on the corners, it can eat 4 gliders at once! It probably won't be used, as it's LUDICROUSLY huge!

EDIT:
I'm dissapointed of my explanation of its eating properties.

EDIT:
I hate my typo.

[Sphenocorona]

1: For small things (like typos) which nobody has responded to, it's OK to make an edit directly to what you wrote before without making an "EDIT" statement at the bottom.

2: Still lives on their own are extremely trivial as discoveries - it may be time consuming, but it's not hard to make a big one by hand, for example here's an asymmetric still life that I made by hand in less than 30 minutes (a search program can create a still life in less than a second):

Still lives are only really interesting if they are catalysts or signal wire components, and in such cases it's only the active region (with bushing) that is of interest (except in the case of synthesizing them, where the casing's synthesizability matters). Here, the active regions are able to be minimally supported by just an eater.

The other type of 'interesting' still life is one that is supposed to be a picture of something, which normally is not used for a post of its own but maybe in a profile picture or background or something.


The trivialness of finding still lives makes me think of a question about the nature of such patterns, though - one that may actually be very difficult to prove true or false. The problem is similar to the method used to prove the four color theorem, about if there are a finite amount of patterns which any still life can be made out of. The idea is more subtle than that, and I don't know how to phrase it properly - it might just be pattern recognition of the small scale support structures, and that there's nothing about them that makes any of those distinct from some giant convoluted and heavily interconnected still lives.

What should we name it?

I'm tempted to alter the problem statement a little. As stated it seems like it's trivially true -- you can pick out a few small NxN patterns, let's say, and they'll work to build any still life. It's going to be all the NxN patterns that (1) don't contain any cells with more than three neighbors, and (2) don't contain any cells-not-next-to-an-edge that have fewer than two neighbors.

The minimal set is obviously when N=1: b! and o! can certainly build all still lifes. But of course they can build everything else, too. N=2 doesn't help anything, because all combinations of ON and OFF cells inside 2x2 can perfectly well be part of a still life.

N=3 starts getting interesting, and in fact I'd conjecture that it's the minimal set (with a caveat detailed below). We get to throw away lots of 3x3 tiles where one or more of the cells is in the wrong state for what's around them. When we've discarded those, what's left is the set of Still-Life Compatible 3x3 Tiles.

Now, if we're allowed to just stick 3x3 tiles next to each other, we can still build lots of things that aren't still lifes. For example, one parity of a glider can be divided into two Still-Life Compatible 3x3s. It doesn't do any good to go to N>3, because you could still build a glider with two SLC tiles for any size N. So how do we make sure that we can build all still lifes and nothing but still lifes using this set?

Seems to me that it will work to pick a tile from the set, and then for each cell on the edge of that tile, pick another tile in the set that overlaps correctly with all tiles chosen so far... and continue picking tiles for newly added cells until we've picked the empty tile for every cell all the way around the edge of some MxN rectangle, at which point we can safely stop.

How many tiles are there in the Still Life Compatible 3x3 set? And how many if rotations and reflections are allowed? Obviously it isn't an unmanageably large number.

-- Probably someone has thought of all this a long time ago, and worked out all the details. But I don't remember seeing anything about it anywhere ... so I really hope the someone wasn't me.
