I haven't seen many multitype CAs in the past
Those are the only ones that really interest me; the
singletype ones usually don't have the same sorts of
complex interactions.
If you want to see the interactions change, play with
the numbers in the arrays in the values of %t (where
it is defined at the beginning of the script). These
numbers effect how each type grows or reproduces, how
longlived each cell can be, and how easily they die
from isolation or crowding. Not necessarily in that
order, of course. The numbers in the version I posted
give a fairly interesting scenerio, but I'm sure there
are other possible sets of interaction to uncover.
For example, maybe the symbiotic + and x types are
too robust, and perhaps the fastgrowth type is too
wimpy. Perhaps if their numbers were tweaked a bit,
you could get a more stable environment where they can
all coexist for a longer period of time...
