WebbSince a QP problem is a special case of a smooth nonlinear problem, it can be solved by a smooth nonlinear optimization method such as the GRG or SQP method. However, a faster and more reliable way to solve a QP problem is to use an extension of the Simplex method or an extension of the Interior Point or Barrier method. Webb1 aug. 1993 · A comparison of the proposed method with an efficient simplex code (MINOS) is carried out by solving SCED problems on two standard IEEE systems. The results show that the interior point technique is reliable, accurate and more than two times faster than the simplex algorithm.
