On modeling environmentally-sensitive growth forms and cellular automata using multiset transformation

We demonstrate the usefulness of multiset transformation for modeling growth processes which combine generational growth with environmental-sensitivity (such as photo-sensitivity and geometric constraints). Our examples are artificial structures with no immediate counterpart in physics and biology. However, our studies are intended to show the feasibility of multiset transformation for more realistic models. We show that multiset transformation is useful both as a formal and a computational model of growth processes.
