snoitareneG Rules

Postby Saka » July 2nd, 2017, 3:58 am

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).
@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
0,1,1,1,1,0,0,0,0,2
2,a,b,c,d,e,f,g,h,1
1,0,0,0,0,0,0,0,0,0
1,1,1,1,0,0,0,0,0,0
1,1,1,1,1,0,0,0,0,0
1,1,1,1,1,1,0,0,0,0
1,1,1,1,1,1,1,0,0,0
1,1,1,1,1,1,1,1,0,0
1,1,1,1,1,1,1,1,1,0
1,1,1,1,1,1,1,1,1,0

@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
0,1,1,1,1,1,1,1,1,3
3,a,b,c,d,e,f,g,h,2
2,a,b,c,d,e,f,g,h,1
1,0,0,0,0,0,0,0,0,0
1,1,1,1,0,0,0,0,0,0
1,1,1,1,1,1,1,1,1,0

@RULE sraWratS

@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

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

c/20 orthogonal, reminds me of the 2x2 c/8 diagonal.
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.
there may be bugs in gfind
