Application of a globally convergent hybrid conjugate gradient method in portfolio optimization
Application of a globally convergent hybrid conjugate gradient method in portfolio optimization
Abstract In this paper, we propose a modification that improves efficiency, robustness and reliability of the famous HS conjugate gradient method. In particular, we propose a hybrid of the HS and DHS methods, where DHS is another recent modification of the HS method. Irrespective of the line search, the search …
