Hi all!
The objective function I want to minimize contains about 10 to 20 variables,
maybe more in the future. I never solved such problems in R, so I had no
idea about the efficiency of R's optimization functions. I know doing loop
in R is quite slow, so I am not sure whether this shortage influences the
speed of R's optimization functions.
I would be very appreciated if anyone could share some experiences with me.
The speed, stability of the R's optimization functions. Is it helpful to
call a C/Fortran code to do the job, if possible.
Many thanks in advance.
