Dear Kai,
you might want to look at function autofitVariogram in R package
automap, which exactly tries to do this. It uses reasonable default
(starting) values, but as any algorithm, it may not work well with
particular input data that is extreme in some sense.

Hi folks,
I am working on a problem dealing with fitting variogram automatically due to a
large dateset. Gstat R package is used to conduct this work. Part of this work
is to compare performance of different kriging methods. The comparison criteria
is RMSE. I am using fit.variogram function
