Thread for basic non-CGOL questions

I have been trying to figure out this for a while but why are almost all B34 rules explosive?

Mainly it's rules in the B34/S23 and B34/S34 rulespace that explode. Rules such as B34/S15 do not explode.

Because those birth transitions are exceptionally powerful. B3 allows outward expansion, and B4 additionally makes it even easier for cells to be born around the edges of a finite pattern.

Thanks! A summary of the transitions that make B34 rules explosive:
B4a, B4w and B4n makes it even easier for cells to be born around the edges of a finite pattern.
B4k promotes chaotic growth
B4y, B4z, B4r and B4q allows long-lasting regions of chaotic activity (In order of effect strength)

Is Langton's Ant Turing-complete?

[EvinZL]

Under what seems to be the standard-definition of turing-completeness here, Langton's ant is turing complete.

This is my first post here. Thank you very much (to the moderators) for allowing me to join.

My question: Is there a rule (can be outer-totalistic, isotropic, or LtL (Larger-than-Life)) that you have encountered with as many 4-cell stable objects (still-lifes or oscillators) as possible? Let's start from 39.

Welcome to the forums!
There are range-1 isotropic rules known to have a family of 3-cell oscillators or 3-cell spaceships, adjustable ad infinitum.

A very simple rule with just two isotropic transitions have another infinite class of 4-cell oscillators based on bounded XOR replicators:

Code: Select all

x = 51, y = 14, rule = B2a/S0
obo$2bo2bo2$o2bo$3bo4bo2$o4bo$5bo8bo2$o8bo$9bo16bo2$o16bo$17bo32bo!

If you have an explicit example rule that backs up the number 39, you may just as well post it directly — no need to ask this kind of question beforehand
EDIT: or did you get it from this post, which suggests that there are this many patterns with MCPS = 4?

Thank you for your kind reply. I am still learning how to post my questions.

Your solution is very interesting and simple. I have not thought of this method before.

The rule I was referring to is my own. Here is the rule with the 39 4-cell still-lifes and oscillators:

Code: Select all

x = 191, y = 25, rule = R3,C2,S2,B3,N+

The range-4 version has 114, and in general the range-n version has at least n(2n^3+3n^2-2n+3)/6.

MAPAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA as a ruletable (symmetries: none)

MAPAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA as a ruletable (symmetries: none)

Python:

Code: Select all

with open("aaa.rle", "x") as aaa:
	print("@RULE AAA\n\n@TABLE\nn_states:2\nneighborhood:Moore\nsymmetries:none", file=aaa)
	for i in range(0,256):
		bin_string = [x for x in bin(i+256)[3:]]
		print("0,", end="", file=aaa)
		for j in bin_string:
			print(j + ",", end="", file=aaa)
		print("0", file=aaa)
		print("1,", end="", file=aaa)
		for j in bin_string:
			print(j + ",", end="", file=aaa)
		print("0", file=aaa)

That should do it
