The Quadratic Solver

The Quadratic Solver includes all of the features of the Premium Solver, plus a new, much faster algorithm for solving quadratic optimization problems (QPs). These problems have a quadratic objective function (in which variables can be squared or multiplied by each other) and all linear constraints; they are often used to find "efficient portfolios" of securities using the Markowitz or Sharpe methods. Where the standard Solver employs the much slower nonlinear GRG method on problems of this type, the Quadratic Solver employs methods specially suited for these problems to find more accurate optimal solutions in a small fraction of the time that otherwise would have been required.
