Hello, I'm using ECJ and GEP extension made by Bob Orchard to develop a little program to find functions from values (something like interpolation). I developed the GUI, and i can run from my java app the Evolve class in order to obtain the function, but, the problem is that the result is printed to the output and i want to get it by a method call or something like that. The result, is printed in this format: MATH ((x+((y+y)*(y+y)))+(x+x)) MATH (SIMPLIFIED) 3*x+4*y^2 Found Ideal Individual ________ But i can't find the class where this result is printed, in order to modify the code a little bit to be able to get the result using a method call like "getResult()" or something similar. Can anyone help me and told me in which class is this print? Thanks.
