Jul 14, 2011 at 14:19 comment added whuber @user603, in a deleted reply, has pointed out that this is likely a quadratic program (because that is what CPLEX does and, I would like to add, portfolio mean-variance optimization is usually formulated as a quadratic program). Usually one is much better off using optimizers written specifically for quadratic programs rather than with general-purpose nonlinear optimizers. That can help limit the search for packages.
