Hello,
Just to let you know, I have added an implementation of the Fletcher
BFGS algorithm to the GSL CVS repository at
http://sourceware.org/gsl/devel.html - it gets the number of function
and gradient evaluations on the test problem down to (60,44) compared
with (56,50) in his book. Thanks for the information on that.
Hi Brian,
Thanks for closing this matter. I think your users will benefit a lot
from this much more efficient line search approach.
Alan
