if you have everything including a GUI ready, isn't the Player Pro a
reasonable alternative? You would just have to create an encoded package
from your code and it would cost something around 300$ per license (you
should talk to WRI for details).

It really depends a lot on what functionality that Mathematica provides
you are using in your code. What kind of numerical routines do you use
(NSolve,FindRoot,NDSolve,NMinimize,Fourier...)? Do you use any symbolic
methods? Do you use any of the visualization functionality, if so which?

What are the priorities and boundary conditions for creating such an
application: target time to market, dependencies on other products/ease
of installation, target platforms, costs, execution speed, prior
knowledge and preferences of developers...

Only if you can provide more details a good choice can be suggested, in
principle you can do everything with any of the possibilities (and a
couple others), it is just a matter of how much time and effort you are
willing to spend.

My personal experience tells me that the knowledge of the developers and
their preferences is crucial to success: results will be so much better
if they try to proof their suggestion will work than when they try to
proof something they don't like will not work :-)

hth,

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.
