Dear Marc,
I found a similar situation. I have to minimize a very expensive
functional as well (>99% CPU). The ideal thing to do would be to
contribute better minimization algorithms to the GSL codebase. Because I
have no time to do so, I looked for other alternatives.
I found a very good optimization code that is very similar in spirit to
GSL:
http://csmr.ca.sandia.gov/opt++/
It took me like an hour to fix my C program's header files and write
function wrappers for use in OPT++. Maybe you should explore this
avenue.
