snoitareneG Rules

Has anybody messed around with snoitareneG rules? These are reverse generations rules, cells take time to be born (but still take up space). I have created 3 snoitareneG rules, but they are all explosive. I made sgorF (Frogs), srallipretaC (Caterpillars), and sraWratS (StarWars).

Code: Select all

@RULE sgorF

@TABLE
n_states:3
neighborhood:Moore
symmetries:permute
var a = {0,1,2}
var b = a
var c = a
var d = a
var e = a
var f = a
var g = a
var h = a
0,1,1,1,0,0,0,0,0,2

1,1,1,1,0,0,0,0,0,0

1,1,1,1,1,1,1,1,1,0
1,1,1,1,1,1,1,1,1,0

Code: Select all

@RULE srallipretaC

@TABLE
n_states:4
neighborhood:Moore
symmetries:permute
var a = {0,1,2,3}
var b = a
var c = a
var d = a
var e = a
var f = a
var g = a
var h = a
0,1,1,1,0,0,0,0,0,3
0,1,1,1,1,1,1,1,0,3

c/20 orthogonal, reminds me of the 2x2 c/8 diagonal.

Code: Select all

x = 4, y = 4, rule = sgorF
.B.A$B2.B$3.B$B!

"Incubation" rules, I'd say. I won't play around too much with these unless a Rule-Table-generating script is written, but the concept seems interesting. Namely, it would allow rapid death of asymmetric areas while the potentially asymmetric birth area grew, so I'm guessing many of these will have a more strongly pro-symmetric induction compared to regular two-state rules.

It is basically the snoitareneG rule B1/S0/sG3/V, but some auxiliary transitions are added in order to prevent explosions.

819-generation methuselah:

7-cell infinite growth:

It's sort of a shame the diagonal wicks can only be destroyed from the endpoints.

Code: Select all

x = 33, y = 28, rule = B1S0
30.A$32.A$32.A6$.2A2$A8$16.B$16.A$15.A$14.A$13.A$12.A$11.A$10.A$9.A$

Please don't name your rules with the same name as Quicklife rules..
