looking for algorithm

[Charles P. Reese]

Hi,

I didn't see this in the GSL manual, but I thought I would ask anyway. 
I'm looking for a multidimensional minimization algorithm that does not
require evaluation of the gradient.  I would like something compatible
with the GPL because I want to release code under that license, but at
this point I will take anything that works.

Thanks,
