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
