Question
Consider a portfolio selection problem
where Ris the target return rate on the
expected return of the portfolio. The set of
feasible portfolios is denoted by XCRN and
it is to be assumed that this is a compact
convex set.
please solve this:
Formulate an optimization problem for
finding a feasible portfolio with the largest
value of Sortino ratio. Also state, with
justification, whether your objective
function is convex or concave or neither.
