I am a new user of ECJ. I have some queries about ADF. Hope someone could 
How can I control ADF tree size? It looks like it goes through crossover 
and mutation just as the Main tree. I guess the parameter, 
gp.koza.xover.maxdepth will affect all trees, main one, ADF trees. Could I 
set it separately for Main tree and ADF trees? such as I need the main 
tree has depth 10 and the ADFs have depth 5. How can I set it?
Many thanks and looking forward to your answer.
