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
