Code: Select all
@RULE HexBuss
Author: Andrew Trevorrow (andrew@trevorrow.com), Oct 2009.
The following Python transition function implements Frank Buss's
3-state rule on a hexagonal grid, as described here:
http://www.frank-buss.de/automaton/hexautomaton.html
The @TREE data was created by copying the Python code to the
clipboard and then running Golly's make-ruletree.py script.
-------------------- start copying
name = "HexBuss"
n_states = 3
n_neighbors = 8
def transition_function(s):
# s[0..8] are cell states in the order NW, NE, SW, SE, N, W, E, S, C
# but we ignore the NE and SW corners to emulate a hexagonal grid:
# NW N NE NW N
# W C E -> W C E
# SW S SE S SE
# set n1 and n2 to the number of neighbors in states 1 and 2
n1 = 0
n2 = 0
for i in xrange(8):
# ignore s[1] and s[2]
if i < 1 or i > 2:
if s[i] == 1: n1 += 1
if s[i] == 2: n2 += 1
if s[8] == 0 and n1 == 0 and n2 == 1:
return 2
elif n1 == 1 and n2 == 1:
return 1
elif n2 == 2:
return 1
elif n2 == 3:
return 2
else:
return 0
