With the help of the CGP framework, I implemented a small problem which is
roughly the same as the first float-based regression problem that is part of
the cgp-package. Maybe I'm doing something wrong but I'm wondering that the
achieved fitness scores are "jumping around". Whereas in my classic ECJ/GP
implementation the scores are monotonically decreasing with every generation
in ECJ/CGP they often alternate and do not show such a trend. Do you have an
idea what the reason for this behaviour could be?
Thanks in advance!
