Nonlinear programming in SciSmalltalk?

Hi,

I wonder if there is something to apply nonlinear programming in SciSmalltalk

What I need is very easy, I have a vector {x1 x2... xn} and a function over these elements f(x1...xn), I want to maximize this function with the constraint

that x1 + x2 + ... + xn = 1

Is there something to do this?

Hi Sebastian,
no, at the moment there is no constrained optimization routine in scismalltalk. of course you could try one of the unconstrained optimization routines in scismalltalk with some penalty method, but with equality constraints this is not the most successfull way in my experience.

Ah ok, thanks Werner, I'll see what I can do!
