Webstandard quasi-Newton methods (such as DFP and BFGS), it was proved that the ratio of successive residuals tends to zero as the number of iterations goes to infin- ... For example, it is unknown whether the residuals converge like O(ck2), where c\in (0,1) is some constant and kis the itera-tion counter, or O(ck3), or O(k - k), or something else ... 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.
