Hello,



i use ECJ for genetic programming. I have a problem.



One of my nodes is a conditional function:



IfGreater(float,float,nil,nil)



If the first float is greater the first nil is evaluated.

Both float and nil arguments can be subtrees (non-terminals).

My problem is that I want to avoid situation where for example both 

floats or both nils are identical subtrees.

Is there a way to do this?



Andrzej
