Complete rookie here. Just registered. Don't understand half of the jargon. Simple question:

In a slightly modified version of GoL, with the sole addition to the rules that a cell with 6 live neighbours also comes alive, this pattern

0 0 0 0 1 0 0 0
0 0 0 1 1 1 0 0
0 0 1 1 0 1 1 0
0 1 1 0 1 1 0 0
1 1 0 1 1 0 0 0
0 1 1 1 0 0 0 0
0 0 1 0 0 0 0 0
0 0 0 0 0 0 0 0

replicates itself, diagonally, a number of times and then suddenly annihilates all copies except for a few. Then proliferates again. And so on. I think it's rather neat. Maybe this is something all of you know everything about and it even has a fancy name and there have been PhD theses written about it. Maybe not. Either way, I'd like to know. Thanks for your time.

This ruleset is known as HighLife. Indeed, the replicator is well known. See here: http://conwaylife.com/wiki/Highlife

Thanks for quick reply. I think I have even heard of HighLife, not knowing that it was that rule.

Another thing: Is there anyone studying automata in 3-D? I wrote a program for that, with a 26-cell neighbourhood as default, but it was hard to find really interesting rules. Fun to code the environment though.

Posted: **February 5th, 2016, 3:11 am**

Yep, I think we've all had the same issues with 3D CAs - all the rules seem to either turn to dust rapidly or form one big blob... Trying different neighborhoods (such faces and edges only) or weighted rules (two state rules that behave the same after rotation/reflection of the entire grid, but decisions one what happens next are not necessarily based on simply counting neighbors) for them might yield some actual interesting rules that have natural spaceships and natural oscillators, but I haven't seen much effort put into that yet. If you find anything cool on those lines though, I think everyone would be interested in hearing about it.

There are 1.8014398509481984x10^16 (18 quadrillion) 3D semi-totalistic two state rules, there is probably at least one interesting rule.

Most promising rules are those starting with B0 (but not S8), B5, B6, B7, or B9.
My suggestion is; start with B6 and B7 rules.

I am using this post for rookie questions if no one minds XD.

How can we test our newly generated rules against the known collection of rules to avoid duplication?

- Search for the rule on the other cellular automata board

- See if any hauls of it have been uploaded to catagolue

- They would probably name the rule by its requirements anyway somewhere in the post

- https://catagolue.appspot.com/census/b3s23 just replace b3s23 with the desired rule name

Thanks.That's helpful for simple rules with systematic names. But newly created rules sometimes are not systematically classified yet. For example my new rule flashbf7a does not fit into the B/S/K/3 spark notation. Is there an easy way to check duplication in this case?'

BTW, I am having problem in accessing the website but it's probabaly a censorship problem.

Many thanks. Do you happen to know more burning fuses or where I can find them?

There's a lightspeed beehive fuse in one of the predownloaded patterns (not sure which).
Any caterpillar is a fuse being extruded at precisely the speed at which it burns.

Empty cells in the middle of seams are required to have 3-5 neighbors: One from the opposite side of the seam, one from each adjacent cell on the same side, and up to two more if adjacent units extend outward.
Thus, excluding the ends, seams are self-perpetuating.

A turmites rule in a pentagonal neighborhood? I don't know, but check out the Space Fabrication thread.

A turmites rule in a pentagonal neighborhood? I don't know, but check out the Space Fabrication thread.

I meant a modified vonNeumann neighborhood with the central cell included as symmetrical to others. i.e. only the absolute count within this 5-cell (4+1) neighborhood matters

But then how do birth/survival work? What I'm seeing is
K5 5 neighbors on = VonNeumann S4
K5 4 neighbors on = VonNeumann B4/S3
K5 3 neighbors on = VonNeumann B3/S2
K5 2 neighbors on = VonNeumann B2/S1
K5 1 neighbor on = VonNeumann B1/S0
K5 0 neighbors on = VonNeumann B0

This interpretation is right, and is how I implemented the aforementioned k=7 hexagonal rule. However having to make such processing is rather inconvenient than having the k=5 neighborhood implemented ready in golly.

this k=5 neighbor don't fit into birth/survival notation that nicely, and we can easily find a different k=5 neighborhood on a pentagonal lattice. k=5 neighborhood is not uniquely defined, but this k=5 can be viewed as k=4 with extra symmetry.

So how does the rule work in the k5 neighborhood anyway? Tell me that and I can (hopefully) get a ruletable prepared.
