- W2082927083 abstract "Previous attempts to derive quasi-Newton update factors by variational means have foundered on the nonlinearity (in the update increment D) of the quasi-Newton condition. By neglecting the quadratic term in D, the QN condition is linearized, so that it becomes possible to derive a perspicuous recipe for least-norm factor-updates. However, in order to restore the robustness which is lost by this approximation, D is replaced by a suitable multiple of itself, based on minimizing a norm of the discrepancy in the QN condition. The resulting update (in two versions) is compared with the BFGS update for a small sample of “standard” functions. The upshot is that the new factor-update which is covariant under affine transformations is comparable in efficiency with the BFGS update, while the noncovariant factor-update is much worse. A table is given, indicating the numbers of gradient and function evaluations required to bring the function values down to the levels shown." @default.
