Calle, this is really mystifying me -- it works fine here on our machines. Could you run it like this: java ec.Evolve -file c:\temp\tutorial4.params -p print-params=true ... and let me know what the output is. It SOUNDS like you have a parameter file which doesn't have any parameters in it: specifically, ec.params. Any chance you copied that incorrectly? Moving parameter files around is strongly discouraged btw, for various reasons. Sean On Dec 2, 2010, at 10:53 AM, Calle Scharffenorth wrote: > Dear all, > > I am getting into ECJ.
