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.
WebA well-known procedure is the DFP formula of Davidon , Fletcher, and Powell . This uses the same formula as the BFGS method except that q k is substituted for s k.
