摘要
It is known that the quasi-Newton methods are one of the most effective techniques for the solution of unconstrained optimization. Under modification of conventional quasi-Newton equation to make full use of known information like the objective function value, this paper presents three BFGS type algorithms, which have almost the same efficiencies as that of Zhang([6]) and We(1[7]). These modified quasi-Newton methods are globally convergent and possesses superlinear convergence.
