Hello,
I have a question concerning the gsl_multimin algorithms.
I use the standard fletcher and reeves method implemented in gsl. My problem
is due to reasoning about the problem,
the minimum I like to find must have only postive coordinates.
I tried to set up kinda "reflecting boundary", so if gsl puts one of my
coordinates < 0, I lift it up
to a value >0. Now, sometimes when doing this, the algorithms stops...so
*gsl_multimin_fdfminimizer_iterate (s)
returns the error code 1. I do not know why this occurs only
occasionally, maybe you have a better solution
for this?
Greetings,
Gregor
