I hope that the quote you are reporting is inaccurate. I think that most of the people who do CA simulations wouldn't say that CA's are better than DE's, but that they are a useful tool in cases where the essential features of the problem are clear but the DE's are either too complicated to be conveniently solved, or the system under consideration is not sufficiently well understood to be modelled by DE's. (Writing DE's after all requires in-depth knowledge of the inner workings of a system.) Marc R. Roussel mroussel@alchemy.chem.utoronto.ca
