Re: [R] Very slow optim()

As per my post on this, it is important to distinguish between "CG" as a general approach and optim::CG. The latter -- my algorithm 22 from Compact Numerical Methods for Computers in 1979 -- never worked terribly well. But Rcgmin and Rtnmin from optimx often (but not always) perform quite well. Th
