BFGS 校正是目前最流行也是最有效的拟牛顿校正, 它是由 Broyden, Fletcher, Goldfarb 和 Shanno 在 1970 年各自独立提出的拟牛顿法, 故称为 BFGS 算法.(BFGS correction is the most popular and effective quasi Newton correction at present. It is composed of Broyden, Fletcher, Goldfarb and Shanno respectively proposed the quasi Newton method in 1970, so it is called BFGS Algorithm)

BFGS算法(BFGS algorithm),是一种逆秩2拟牛顿法。Hk+,满足拟牛顿方程的逆形式Hk+}少一、k=s.当Hk正定且(,',少)}0时Hkh,也正定,因此,由BFGS修正确定的算法xk+} - xk - HkF Cxk)是具有正定性、传递性的拟牛顿法,它也是无约束优化中最常用的、最稳定的算法之一这种算法是布罗依丹(Broy-den,C. G.)于1969年,以及弗莱彻(Fletcher , R. ) ,戈德福布(Goldforb,D. )、香诺(Shan no, D. F.)于1970年分别得到的,故称为BFGS算法.(The BFGS algorithm is an inverse rank 2 quasi-Newton method.Hk +, to satisfy the inverse form of the quasi-Newton equation Hk +} less one, k = s. When Hk is definite and (, ', less)} 0 Hkh, is also positive definite, therefore, the algorithm determined by the BFGS correction xk +} - xk - HkF Cxk) is a quasi-Newton method with positive definiteness and transitivity. It is also one of the most commonly used and most stable algorithms in unconstrained optimization. This algorithm was Broy-den (CG) in 1969, and Fletcher (R.), Goldforb (D.), and Shanno (DF) were obtained in 1970 respectively, hence the BFGS algorithm.)
