I guess we could do that, but then we don't save any time.  A quick
experiment indicates that we don't output bad results or crash when we
set trade and lux weights to exactly zero.  What were the problems with
zero weights?

Actually not a problem.  The function calc_fitness uses int, which
should be wide enough (unless we go for 16-bit platforms) while we don't
use the weights anywhere else.
