I apologize because there was an error on my yesterday's email:

"The code is based on the eoGeneralBreed.h archive, but I *CANNOT* do what I
want. Indeed, I get the thrown error of OutOfIndividuals."

Excuse me again. Hope you can help me with my hassle.

Thanks a million.
Manuel

Hello again,

first, thanks for your good work tracking the bug I commented to you before.

Second, I have a question. I am using NSGA-II and I have implemented a new
mechanism to select individuals from parents population. So I would like to
apply crossover and mutation operators to these parents. I have created a
kind of eoGeneralBreeder class to do that. The main loop (once parents have
been already selected) is:


------------------------------------------------------
      // my parents have been selected before and allocated in
selectedParents population
      target = howMany(selectedParents.size());

      // I would like to save here my offsprint, in _offspring population
     _offspring.clear();

      // the selection
      eoSeqPopulator<EOT> it(selectedParents, _offspring);

     // till completing the offspring I apply operators with a given
probability
      while (_offspring.size() < target) {
          op(it);
          ++it;
      }

      _offspring.resize(target);   // you might have generated a few more

------------------------------------------------------

The code is based on the eoGeneralBreed.h archive, but I can do what I want.
Indeed, I get the thrown error of OutOfIndividuals. Can you help me?

Thanks in advance.

Best regards,
Manuel.
