[R-sig-finance] Brush-style gradient maximization?

[Vivek Satsangi]

Hello,

Has anyone on this list done a Brush/Shock (1995) style gradient
maximization portfolio construction  thing in R or Splus? If someone
has the beginings of something, this might be something I am
interested in helping implement....

Herr Doktor Würtz? Is this something that interests you? The
omniscient Mr. Krishna Kumar?
Dr. Graves?

p.s. Is the correct spelling of Dr. Diethelm's last name "Wuertz"
instead? Or is the 'e' added in in places where the umlaut cannot be
reproduced? I have seen both spellings, and don't want to rudely
incorect / disrespectful of such a great scholar.

'mank' and 'ind.' What do these words mean? It's a mystery, and that's
why so is mankind."
