Stop using internal APIs you find by reading the source code and
instead read the documentation on one-dimensional minimization:
http://www.gnu.org/software/gsl/manual/html_node/One-dimensional-Minimization.html

If you want to minimize in multiple dimensions, try reading
http://www.gnu.org/software/gsl/manual/html_node/Multidimensional-Minimization.html.
