The Davidon-Fletcher-Powell (DFP) [Section ] method belongs to the family The default initial metric is the identity matrix generated using a MATLAB built. The Davidon–Fletcher–Powell formula finds the solution to the secant equation that is closest to the current estimate and satisfies the curvature condition. A well-known procedure is the DFP formula of Davidon , Fletcher, and Powell [ 14]. This uses the same formula as the BFGS method (Equation 9) except that. 0, ∈, a derivative free method via the classical Davidon-Fletcher-Powell (DFP) update is .
