It seems to me that just the fact that it can isn't enough information. It looks like you need "weighted constraints"; there's 0 chance that a sheep attacks a wolf, but there's >0 chance that a wolf attacks a sheep, >0 chance it attacks a wolf and >0 chance it attacks a lion. The exact numbers will vary, and I have absolutely no idea what they would be like. It probably requires some kind of ranking system that adjusts according to the known animals and their likelihood to attack eachother. I'm pretty sure you can't get this done without defining some triggers. -- Alban Hertroys alban@xxxxxxxxxxxxxxxxx magproductions b.v.
