Pottery (R2,C2,S4,6-9,20,B7-9,18)

[TheWayOfTheCon]

I'm not sure if this rule is threadworthy, but I'm giving it a shot.

This is an HROT rule I found while looking for range-two Life-like rules. It is technically a variant of this rule, which I also named "Pottery", differing only by an added birth and survival transition. But I'm moving the name to this rule because I think its slightly better.

* The following content until the next asterisk will not be updated to include new discoveries

Behavior

Pottery is indeed Life-like, being expansive and long-lived, with identifiable evolutionary sequences and a variety of objects.

x = 0, y = 0, rule = R2,C2,S4,6-9,20,B7-9,18

So far, I've only identified two common evolutionary sequences.

The one on the left is definitely more useful than the one on the right, releasing a spaceship and some other junk, before stabilizing at 164 generations.

Still lives

Some of the most common still lives include a 3x3 block, a hollow 4x3 rectangle (which is a good eater), a weird rectangular one that bulges in the middle, and a 4x4 hollow square. There are many more still lifes besides these, and because of the neighborhood range being two, there are many times more possibilities for still lifes than in the standard range-1.

Code: Select all

x = 45, y = 15, rule = R2,C2,S4,6-9,20,B7-9,18

Interestingly, there are a diverse amount of still lifes with very similar properties. The only thing that actually makes this rule stand out, they are why I gave it the name "Pottery". These are large, hollow, geometrical still lifes that come in many different shapes and sizes, kind of like real pottery throughout the world. They probably don't have many use cases, as they are very fragile.

Oscillators

The most common oscillators in the rule are rather boring. There's a couple billiard tables, a length-two Margolus oscillator, and some other weird ones.

Code: Select all

x = 46, y = 6, rule = R2,C2,S4,6-9,20,B7-9,18

But out of the handful of high-period oscillators, there are three that stand out. In increasing rarity, these are: A period-50 strong sparker, a period-160 RRO, and a period-100 very spurty oscillator.

Code: Select all

x = 77, y = 10, rule = R2,C2,S4,6-9,20,B7-9,18

More high-period oscillators might appear in future agpsearching, but the first two will probably be the basis for most technology since they are the most common (the p100 has only happened in C2_1).

Spaceships

There are five natural spaceships in the rule. Two of them, a c/3d and c/6o, are by far the most common. The relative frequency of both spaceships combined (15.4) is still lower than the relative frequency of Life's glider (11.4).

As for the p100, I'm just not interested in it, so someone else can take a look at it.

Using four copies of the p160, I was able to make the first gun in this rule, firing the c/3d. Finding guns with these super sparky high-period oscillators is essentially a matter of getting the right reaction from the oscillators's sparks colliding, and seeing if you can turn it into a spaceship. I'd like to eventually see a gun using three or even just two copies of the oscillator.

Goals

• Find five new spaceship speeds (0/5)

• Construct a gun that doesn't rely on the "big 3" oscillators (the p50, p160, or p100)

• Make a gun for all 5 natural spaceships (4/5)

• Find a stable reflector

• Construct a sawtooth

• Prove turing-complete

Search programs that work with this rule

• factoriosrc: Sucessor to rlifesrc that supports HROT. It can pretty much search everything rlifesrc can. Its in early development and is missing a few features.

• CAViewer and cfind: A program that is meant to be capable of simulating a very large variety of rules, including HROT. It has built in searching for catalysts and agars. cfind, a program that comes with CAViewer, is capable of searching spaceships in all rule types supported by CAViewer, although I've found it to be slow and buggy.

If you can find any more programs, let me know.

If c stands for the speed of light in this rule, then your spaceship velocities are wrong, since c in a range-2 rule is 2 cells/gen.

You are correct, but I just kept the speeds measured under the definition if c was one cell per generation, since we're all used to that and it gives us a better initial understanding of the spaceships.

I managed to submit syntheses to Catagolue using CAViewer, but I had to do it in an unorthodox way (just duplicating all the files to be in the apgmera folder rather than the CAViewer folder inside it). The soups are just fine and valid, but only one sample soup was there for each object. So here's the next best thing: The log which contains all the sample soups (including multiple soups for a single object).

x = 4, y = 4, rule = R2,C2,S4,6-9,20,B7-9,18
4o$4o$4o$b2o!

Using two copies of it we get yet another Methuselah, 751 generations.

Code: Select all

x = 5, y = 15, rule = R2,C2,S4,6-9,20,B7-9,18
b4o$b4o$b4o$2b2o8$b2o$4o$4o$4o!

We should do an actual Methuselah search for this rule.

EDIT 3: Yet another common diehard. 472 generations.

Code: Select all

x = 4, y = 4, rule = R2,C2,S4,6-9,20,B7-9,18
b3o$b3o$4o$b3o!

EDIT 4: Common evolutionary sequences that creates the most common pottery,xs28_0g842111248gz78gy3g87zx1244421

Code: Select all

2bo$b3o$2ob2o$o3bo$2ob2o$2bo!

So here are all five common sequences I've identified so far:

Code: Select all

x = 140, y = 7, rule = R2,C2,S4,6-9,20,B7-9,18
104bo$70b2o30b3o32bo$3o41b3o22b4o28bo3bo30b3o$3o41b3o22bo2b2o27b2obo30b

Considering this is LTL, there could be many times more sequences here than there are in Life, but it does look like these four can be used to sum up a good amount of chaotic behavior in this rule.

[TheWayOfTheCon]

Factoriosrc has confirmed (or more like claimed, it isn't a dedicated spaceship searching program) that no D2| c/3o spaceships exist at a width of 14.

A random partial:

Code: Select all

x = 12, y = 9, rule = R2,C2,S4,6-9,20,B7-9,18
3b2o2b2o$2b2o4b2o$b2o6b2o$o10bo$2o2b4o2b2o$4o4b4o$b2o6b2o$b3o4b3o$bob
2o2b2obo!

EDIT: 4x4 hollow still life catalyzes part of the tridecamino, but is destroyed by the rest of the chaos.

Code: Select all

x = 27, y = 14, rule = R2,C2,S4,6-9,20,B7-9,18
23b4o$23bo2bo$23bo2bo$23b4o6$3o$3o$3o$3o$o!
#C [[ T 129 PAUSE 1 ]]
[[ T 129 GPS 10 ]]

Could we turn this into an actual catalysis?

EDIT 2: This reflects the tridecamino! But it creates some junk.

Code: Select all

x = 33, y = 9, rule = R2,C2,S4,6-9,20,B7-9,18
3o$3o$3o$3o$o$30b3o$30bobo$30bobo$30b3o!
#C [[ T 181 PAUSE 1 ]]

This and the previous reaction were found by CAViewer's built in catalysis search.

And also, continuing the pattern we find that the emitted c/3d would collide with one of the still lifes. So we can't made a gun out of this specific reaction.

Code: Select all

x = 63, y = 63, rule = R2,C2,S4,6-9,20,B7-9,18
23b4o$23bo2bo$23b4o16$30b3o$30b3o$30b3o$30b3o$30bo$60b3o$60bobo$60bob
o$60b3o10$3o$obo$obo$3o21$36b4o$36bo2bo$36b4o!
#C [[ STOP 150 ]]

Buuut if we could figure out a catalysis for both the junk and the spaceship, then we would get an engineered period-724 oscillator.

The regular c/3d stable eater doesn't work, it interferes with the tridecamino later on.

Code: Select all

x = 63, y = 63, rule = R2,C2,S4,6-9,20,B7-9,18
23b4o$23bo2bo$23b4o16$30b3o$30b3o$30b3o$30b3o$30bo$3b4o53b3o$3bo2bo53b

By the way I've also begun to work on a user page for this rule, which you all have permission to edit: User:TheWayOfTheCon/HighPottery

[TheWayOfTheCon]

Looking for a c/3d reflector using the period-50 oscillator, here's an interesting reaction.

Code: Select all

x = 25, y = 38, rule = R2,C2,S4,6-9,20,B7-9,18

2o2bo$17b3o!

Using a reflector, one could maybe construct a pseudo-period 50 gun using pifricted's p100 gun, assuming to oscillator wont interrupt the glider stream.

A large common spark:

Code: Select all

x = 5, y = 5, rule = R2,C2,S4,6-9,20,B7-9,18
b3o$4o$o3bo$4o$b3o!

Not particularly interesting, but a 19x18 soup that happens to produce the same odd constellation twice.

I think this spark from the c/3d eater could be perturbed by other still life's, maybe resulting in a stable reflector or converter.

Over 400 results were picked up over the course of a few hours, using a large pool of 60 random still lifes I found on Catagolue to choose from. Many of the results are false alarms, but that doesn't mean there isn't anything interesting left to go through.

I think this rule deserves a thread, really cool rule.
Ima run apgsearch for c1 all night and see what if it finds anything new.

I'm glad you like it. This is the rule I've been focused on over the past couple of weeks, my attention has shifted from Flockenstein to this. Doesn't mean I'm done with the rule, I just haven't found a good balance.

Anyways, I think this has some serious conduit potential.

Now, four out of five of the naturally-occuring spaceships in this rule have a gun. The last on the list is the largest and rarest: The 6c/24.

Code: Select all

x = 11, y = 5, rule = R2,C2,S4,6-9,20,B7-9,18

I mainly made this gun, not just to fire the c/4d for the first time, but to also demonstrate and test the potential for technology in this rule and large, engineered patterns.

EDIT:

Some better syntheses.

A clean 3D synthesis of the c/2.

And a dirty 3D synthesis of the c/4d that, not only is cheaper, but also outputs two c/3ds!

You can stabilize them from both edges to make an extensible oscillator, and they also work as an agar.

I don't think it can be successfully made into a full catalyst though, since the 3x3 block has to be pretty much fully absorbed by the chaos for it to work.

EDIT 5: Two c/3 partials that I think have good potential for extension. And indeed, factoriosrc was able to extend them (a bit).
