Constrained Optimization routine [message #45252]

Hi all,
I'm wondering if anybody knows an IDL routine to perform minimization
of a nonlinear function given functional constraints on the variables.

I mean: I would minimize a nonlinear F(x0,...,xn) subject to the
constraint G(x0,...,xn)=0, where G is another nonlinear function of the
same variables.

I know the very good TNMIN routine from Craig B. Markwardt, it can deal
very well with simple boundary constraints on each variable (e.g. xi >
low_boundary or xi < high_boundary), but it is not possible to define a
limit constraint which is a function of more variables.

Can anybody help me?
Thank you so much.
Gianluca
