摘要 基于Hiroshi Yabe等提出的新拟牛顿方程,给出了一类修正的BFGS算法,并在一定的假设条件下,结合Wolfe搜索准则证明了该算法具有全局收敛性. In this paper, the authors present a new modified BFGS method based on the new quasi-Newton equation Hiroshi Yabe et. al proposed. Under some suitable conditions, the authors prove the global convergence of their method with Wolfe linear search.
