Rule table: Branches

This rule table expands quickly into colorful, unpredictable branches from simple and/or random patterns. Oscillators appear naturally in the branches. It's my first rule table, so please tell me what you think!

Code: Select all

n_states:5
neighborhood:Moore
symmetries:rotate8reflect

var z={0,1,2,3,4}
var x={1,2,3,4}
var y={1,2,3,4}

It produces some intricate, dendritic, coral-like structures. There are several types of infinite growth pattern, the most interesting comprising two halves with a blank diagonal between them. This type of puffer has a relatively high period, as compared with the others.

The rule is more interesting for its aesthetics than the actual behaviour, contrary to most cellular automata. You can easily make undersea images by taking a screenshot of Golly and adding a few sea creatures in Microsoft Paint. Please excuse my terrible drawing skills; you could probably do this six orders of magnitude better than me. :)

Wow! It does look cool :P

An interesting thing to note about the rule is that, while all states behave in the same way on their own, they move differently when combined.

State 1 and 3 interact on a different way with each other than with state 2 and 4; the same kind of relation happens between 2 and 4. They seem to "stop" each other. This is most commonly observed on simple patterns, which develop in completely different ways:

Code: Select all

# States 2 & 1
x = 5, y = 5, rule = Branches
$.A$.2B$.2BA!

# States 2 & 4
x = 5, y = 5, rule = Branches
$.D$.2B$.2BD!
But two patterns with the colors in the same order are exactly the same. For example, 2 & 3 versus 3 & 4.

EDIT: Also, how many different infinite growth patterns have you found? I've only found three:

The blank diagonal, a puffer with period near 200 (here, a double blank diagonal with slightly asynchronous sides):

Code: Select all

x = 7, y = 4, rule = Branches
$.2AB.D$.B.D2C!
The "tree"? (again, a double tree):

Code: Select all

x = 3, y = 3, rule = Branches
.A$.A$3A!
The helix:

Code: Select all

x = 3, y = 8, rule = Branches
.C$.D$3A$.B$.B$.B$.B$.B!
Sometimes, a "branch" gets stuck on a tree, bouncing on and off it constantly at a slightly lower velocity than the tree's.

EDIT2: This is what I mean by "branch stuck on a tree":

Code: Select all

x = 46, y = 6, rule = Branches
.A$.A$3A$44.C$44.C$43.3C!

Neat rule, and looks turing complete as well. Here are some "trains" I found:

There's another impressive infinite growth pattern:

This runs incrementally faster than the blank-diagonal puffer, so it out-competes it when they are in close proximity.

A variation of the helix. In this one, the branches are connected.

Code: Select all

x = 10, y = 8, rule = branches

Impressive, indeed. :o

It does run faster than the blank diagonal, but the difference is almost zero: It took 30000 generations to destroy the blank diagonal.

Also, it needs a name :P Ideas?

And how do you view this?

What? :D You copy the code from the first post to a file, save it on the Rules folder as Branches.table, and then set the rule in Golly.

Unidimensional starting patterns produce weave patterns with fewer dendrite structures:

Code: Select all

x = 163, y = 1, rule = Branches

The vertical centerline looks like a 2c signal but it is of course an optical illusion.

knightlife, I've been playing with unidimensional seeds. The "weave pattern" of a seed of width 177 seems to be non-periodical:

Code: Select all

x = 10177, y = 1, rule = Branches
5000D177A5000D!
Other weave patterns (like 34, the one you showed, or 43, which has a surprisingly long period when compared with 34) are also interesting.

EDIT: I'm testing some other patterns, I'll write here the results. (I'm only posting the relevant ones)

width 59 -> period 440
width 63 -> period 380
width 67 -> period 1062
width 71 -> period 1826
width 75 -> period 1864

It doesn't work. (At least I have my posted rules...)

Weird...

Here, I uploaded it for you. Just copy it inside Golly/Rules/.
