Hi Ravi,
that's an interesting claim and N-M. Can you provide any reading matter to
support it?
Cheers,
Andrew

I agree with John that SANN should be removed from optim.
More importantly, the default choice of optimizer in optim should be changed
from "Nelder-Mead" to "BFGS." Nelder-Mead is a bad choice
for the most commonly encountered optimization problems in statistics. I really
do not see a good reason for not changing the default in optim.
Best regards,
Ravi
