Re: [gplab-users] Confusion in Fitness function in GPLab

[Atif <ati...@na...>]

Thanks Ma'am Sara,
          In my experiment, *best so far* and *test fitness* are always
coming the same. Why is it so?

On a separate note, I'm using Daily Stock Data. Accordingly, I don't have
output files. As GPLab requires both input and output files for the
successful run so I've given the same input file as my output file, (see
below code lines)

     p.datafilex='training.txt';
     p.datafiley='training.txt';
     p.usetestdata=1;
     p.testdatafilex='testing.txt';
     p.testdatafiley='testing.txt';

However, I don't use these output files in the fitness function.

Thanks Indeed !!!
