Hi all,
I am trying to minimize the quardratic form w'Aw, with certain
constraints.
In particular,
(1) A=(a_{ij}) is n by n matrix and it is symmetric positive definite,
a_{ii}=1 for all i;
and 0<a_{ij}<1 for i not equal j.
(2) w'1=n;
(3) w_{i}>=0
Analytically, for n=2, it is easy to come up with...
