Shouldn't these be considered Eater Siamese Eater??

Code: Select all

x = 35, y = 8, rule = B3/S23

Nope. Siamese means sharing cells. These are merely touching.

Sorry, no. "Eater siamese eater" cannot have 14 or more cells, so there are only four types of "Eater siamese eater".

*EDIT: This reminds me of that "b siamese p" joke. Sorry, I forgot where it was.

"b siamese p"

You mean This?

Yes.

Another question: Chaotic growth is proved to exist in OCA. But if you simulate
a chaotic growth in Life using the 0E0P metacell, will it be treated as a Chaotic Growth?

Is there any name for this oscillator or any relative? Feel like it has to be known.

Code: Select all

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

indeed-- it is a Two eaters stator variant/dimer

What about Replicators and Reflectorless Rotating Oscillators?

Chaotic growth occurs in an infinite field; otherwise, in a finite field, the best you get is oscillation (i.e. an MxN box necessarily eventually oscillates with a period < 2^(MN)).

To simulate chaotic growth with metacells, you'd either need an infinite agar of metacells, or a breeder that constructs an ever-growing finite array of them at a speed at least as fast as the metacell clock speed.

That's why ColorfulGalaxy mentioned 0E0P metacells: the ground state of the 0E0P metacell is empty, with each metacell having construction arms capable of building its neighbours in the surrounding empty space.

Hi! I just registered after discovering this game. How do I post an initial state using the viewer?

[mniemiec]

Welcome to the forums! First, start with an RLE image, such as what Golly exports. Then, enclose it in a Code block, like this:

(code)x = 9, y = 8, rule = B3/S23
2o$bo$bobo$2b2o$5b2o$5bobo$7bo$7b2o!(/code)

except using square brackets instead of parentheses, like this:

Code: Select all

x = 9, y = 8, rule = B3/S23
2o$bo$bobo$2b2o$5b2o$5bobo$7bo$7b2o!

How common are natural glider (or any other spaceship) eating reactions? Is there a soup (there must be) where the glider producing switch engine's gliders get eaten.

Yes, D8_1 and D8_4 have a few. Not the GPSE though—that fires its gliders forwards.

Do they have the same or different apgcodes?

Linear growth "apgcodes" uses merely the soup's hash, so no.

I'm not sure, although you should probably check the ZZ_LINEAR soups.

EDIT:

Not the soup's hash. It's a hash of I think either the population change or a few points in time concatenated together.

What is a hash here? Is it just a simple function that makes a number?

I'm not sure, although you should probably check the ZZ_LINEAR soups.

So is there any way of finding them? Also, other than that how common are spaceship eating reactions?

How common are spaceship eating reactions, uh who knows? How are you supposed to search randomly for them?

Many glider syntheses, especially those from random collision enumeration, start from a 2-glider collision; and other gliders join in the reaction some (say, 4)or more generations later. These syntheses necessarily begin with one of the 71 possible 2-glider collisions. So, what's the frequency of any of the 2-glider collisions serving as the initial interaction in a glider synthesis? (For instance, how frequent is a 2-glider mess involved?)

(For instance, how frequent is a 2-glider mess involved?

Most such collisions involve 2-glider collisions that take a relatively long time. E.g. the number of ways of colliding an additional glider into the common 2-glider collision that makes a block is severely limited, because that stabilizes in 4 generations. Collisions that make methuselahs, on the other hand, have hundreds of way of adding an additional glider.

I just downloaded JLS and in the JLS manual pdf it says:
"The program can be started from command line by issuing the following command:
java -jar JavaLifeSearch_1.7.jar".
I assume that means the command prompt. But when I put it there I get this message:
The system cannot find the file C:\ProgramData\Oracle\Java\javapath\java.exe.
I don't have anything called ProgramData on my computer.

Did you install JDK and add it to the PATH, though?
That *might* be one of the default search paths when Java is not found, but I'm not sure.

I have JDK. What do you mean by PATH? Sorry, I'm not good at technical stuff.
