Hi,
In manual for optim() function, there are three control parameters for
Nelder-Mead algorithm: alpha (reflection),beta(contraction) and
gamma(expansion), but in the original paper, there is another parameter
delta which controls shrinkage, how can I set this shrink parameter? Or is
beta actually the same meaning as delta?
TIA
