On initial stage even $300 is too much, as I can see.

The key numerical function is NMinimize. I found powerful lib Ipopt
http://www.coin-or.org/Ipopt/ with java interface. There are some
difficulties now with it for large target functions but I hope to
solve them.

No. At final step there are many (limited number) numerical
calculations.

Thanks for the answer.
