Subject: multidimenstional minimization without df.
Date: Tue, 22 Jan 2008 17:26:00 -0000 [thread overview]
Message-ID: <4795F855.6010105@physics.gatech.edu> (raw)
Hi,
I'd like to locate the minimum point of a function f(x_i) of n variables
x_i. It's very non trivial to calculate the df/dx_i. Can I use conjugate
gradian method without this df(x_i) information ?
This page in the manual
http://www.gnu.org/software/gsl/manual/html_node/Multimin-Algorithms.html
doesn't list gsl_multimin_fminimizer_conjugate_fr as a type of
minimizer. It has
gsl_multimin_fdfminimizer_conjugate_fr
but no
gsl_multimin_fminimizer_conjugate_fr
Any help would be appreciated.
Thanks,
Toan
