Sorry for the troubles, but I've re-read the manual several times and it
doesn´t clarify my question.
In genetic algorithms, evolution strategies, etc, it is specified a
probability of doing recombination, and another one of doing mutation. And,
I want to do the same for genetic programming, an I don´t see the way to do
it in ECJ.
Thank you anyway.
Regards.
