You have a large search space so you will _always_ need many evaluations.
Genetic algorithms converge relatively fast, and it does a global search unlike
the steepest decent scheme of backpropagation. If you do it right genetic
algorithms can converge faster than backpropagation (well at least for some
problems eg. feed forward networks).

Anyway, there are lots of ways to fit the parameters once you have something to
fit them by, getting the eval and getting it cheap is the problem.
