<div>Hi everyone,<br></div><div><br></div><div>I want to solve quadric programming problem which is optimization of Markowitz portfolio. I wonder whether Ipopt is the best (or one of the best) tool for quadric programming. What is the quality of solutions in comparison to Generalized Reduced Gradient algorithm, which is used in Microsoft Excel? Are there significant differences in speed?</div>
