- ECAL-91 Interactive evolution of artistic images. 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 processor per cell. 256*256 arrays processed at interactive rates. Mutations and crossovers performed in a front end machine. Genotypes evolved (interactively) "in timescales such as 10 minutes"
