This is my solution. Maybe there's a better one.

I've derived my own genome from GA*Genome, redefining the initilize method
for initializing the genes with special values. The special values, in my
case, are specified in a file.
Instead of creating a population by cloning MyGenome, I've add N MyGenome
that are initialized randomly and M MyGenome that are initialized from
file. The initialization method depends on a flag that is a data member of
MyGenome.
To get the expected results I had to decomment a line of code in GALib in
the file gasimple.ccp that initializes oldPop. You may find this line of
code in the initialize method of GASimpleGA.

I hope my explanation will help you,

Cristina.
