[GiNaC-list] constrained, parametric optimization

[Luca Dall'Olio]

I am developing a computer program which needs to solve a constrained,
parametric optimisation, something like :

meaning to calculate min(x) such as y = b*x+a and x <= c and x >=0
where x and y are variables, a, b, c are constant but unknown parameters.
Since the problem is calculated at runtime from my computer program and
changes every time, I think I need to solve it with some form of constrained
programming with a symbolic result.

I could see something like this in mathematica :

but I would like to keep my program free and open source, so I would like to
use a free library for this...

could you please tell me if I can do this using ginac?
thank you very much in advance!
Luca
