Just a little remark about the code that has nothing to do with the bug that
has been elucidated by Graig Henderson. When Greg Dehaas wrote:

It seems to me that it would have been more accurate to write:

fncSelection = boost::ptr_fun(GenAlg::RouletteWheel<CGAController, unsigned
long>);

there is no use for the boost::bind function even if the result is finally
the same ;-)
