Numerical experiments on DFP-method, a powerful function

The Davidon–Fletcher–Powell formula (or DFP; named after William C. Davidon, Roger Fletcher, and Michael J. D. Powell) finds the solution to the secant equation that is closest to the current estimate and satisfies the curvature condition. It was the first quasi-Newton method to generalize the secant method to a multidimensional problem. This update maintains the symmetry and positive definiteness of the Hessian matrix. WebJul 1, 2024 · Here, duality means that the BFGS update for $H$ is obtained from the DFP update for $B$ by interchanging $H$ with $B$ and $s$ with $y$, respectively. The SR1 formula is self-dual in this sense. It is clear that all updates from the Broyden family inherit symmetry of the matrix $H$.

DFP has also an interesting property that, for a quadratic objective function, it generates the directions of the conjugate gradient while constructing the inverse Hessian.
