Hi Klaus,

Thank's very much for your fast reply.
I would like to know if there is any configuration
task related to the grid, for example, in wich machine
will run each worker or something like that (I just
see the example to simple...and I have not ran it)

A part from that, now my Ga runs from a main class,
that sets all the configuration needed, generates an
innitial populations and begins a loop to evolve de
genotype. In which of the example classes should this
code fit ?

Regards,

Germán Viera
