Webanl.gov WebNov 26, 2024 · Here, we will focus on one of the most popular methods, known as the BFGS method. The name is an acronym of the algorithm’s creators: Broyden, Fletcher, Goldfarb, and Shanno, who each came up with the algorithm independently in 1970 [7–10]. Figure 2. From left to right: Broyden, Fletcher, Goldfarb, and Shanno.

Webwhy the DFP method is often less suitable than the BFGS algorithm for general unconstrained optimization calculations, and they show that quadratic functions provide much information about efficiency when the current vector of variables is too far from the solution for an asymptotic convergence analysis. Key words ... WebWe will derive a close relative of the BFGS method, called the DFP method, named after Davidon, Fletcher, and Powell 5, and describe its implementation and extension as the BFGS method. We begin with an approximate local model of the objective function f that does not involve the Hessian matrix, (28)
