@RULE Wireworld++

Rule by Vladislav Gladkikh and Alexandr Nigay

Wireworld++ is like 2 WireWorld's mashed together. There are 2 separate WireWorlds inside Wireworld++ - the 'strong' world (states 1, 2, 3) and the 'weak' world (states 4, 5, 6).

Independently, any circuit built entirely out of cells from only one world behave identicaly to regular WireWorld - since it takes 1 or 2 adjacent 'weak' heads (state 4) to turn a weak wire (state 6) into a weak head, and the same goes for the strong wire (state 3) and its heads (state 1).

The power of Wireworld++ arises when one puts the two worlds together. A strong wire will turn to a strong head when exactly two of its neighbors are weak heads, while a weak wire will turn to a weak head if exactly one of its neighbors is a strong head.

With this, it is very easy to construct very small AND and XOR gates. To make an AND gate, connect two weak wires (inputs) to one strong wire (output). To make an XOR gate, connect two strong wires to a weak wire.

The following script was used with the standard script 'make-ruletree.py' to generate the TREE section of this file:

name = "Wireworld++"
n_states = 7
n_neighbors = 8
def transition_function(a):
   nw, ne, sw, se, n, w, e, s, c = a #unpack
   neigh = n, ne, e, se, s, sw, w, nw #repack
   
   BG=0;SH=1;ST=2;SW=3;WH=4;WT=5;WW=6

   shc = 0
   whc = 0
   for n in neigh:
       if n == SH: shc += 1
       if n == WH: whc += 1

   if c==BG: return BG
   elif c==SH: return ST
   elif c==ST: return SW
   elif c==WH: return WT
   elif c==WT: return WW
   elif c==SW:
       if shc==1 or shc==2 or whc==2: return SH
       else: return SW
   elif c==WW:
       if whc==1 or whc==2 or shc==1: return WH

   else: raise ValueError("invalid state: " + str(c))
