[jgap-users] Duplicate chromosomes after running a natural selector.

[GPMatias <ign...@gm...>]

Hi, I been using Jgap for a week or so. I have an issue with
TournamentSelector. If I start with a population of 10 chromosomes, after
operate Tournament on the population I end with 10 chromosomes witch
several are duplicates. Then when I go for crossOver the same chromosome
gets crossOver with itself. I don't see a reason to keep a duplicate. I
couldn't find a way to get rid of them(withow adding any new code to the
framework).. Is there any setting I could pass to Tournament or
configuration to get rid of the duplicate ones?.

Moreover I would like to ask why this has to be that way I couldn't find
any answer reading the code or the jgap webPage

Best regards.
