I am a  new to gsl and I am trying to minimise a multi-dim

My function is calculated externally using an image
and a 3D model projection. I cant think the need for
any parametes as shown in the examples in

If I don't need parameters, should I set it to null like

 my_func.params = NULL;


Also in addition to
gsl_multimin_fminimizer_nmsimplex2 and

I wish to modify the simplex algorithm  to mix it with
simulated annealing so that I can add a random perturbation
to the simplex on each iteration. How can I do that with the GSL
library in the most elegant way?

Thanks in advance
