                 Discusses drawback of using GA to define CA state
                 transition tables. Second half, discrete CA states are
                 replaced by one or more continuous variables, whose
                 initial value and rate of change are controlled by
                 differential equations (which may depend upon the cells
                 state and that of its neighbours). Both initial value
                 and rate of change are given by a lisp s-expressions. 5
                 different types of mutation. {"}estimates of
                 computation times are made, and slow expressions are
                 automatically eliminated before bing used.{"} Crossover
                 not clear: may be different from Koza, exchanging only
                 a single node between expressions rather than subtrees.
                 Also when mated both the s-expression controlling the
                 initial state and the rate of change are crossed over.
                 Some runs use complex (ie i,j) rather than real
                 numbers. Run on connection machine, one virtual

                 in a front end machine. Genotypes evolved
