[Help-gsl] Multimin using simplex and function without parameters

[Srimal Jayawardena]

Hi

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

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

http://www.gnu.org/software/gsl/manual/html_node/Multimin-Examples.html

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
gsl_multimin_fminimizer_nmsimplex2_rand

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

Srimal
