摘要 提出一类更为一般的修改拟牛顿方程,从而推广了已有结论,同时给出了相应的修改BFGS算法,并将它与Armijo线搜索相结合,证明了在适当条件下该算法具有全局收敛性。 The article put forwards a kind of more general improved Quasi-Newton equation.It extends the existed results and bring out an improved BFGS method correspondence.It combines it with Armijo line search method.It testifies BFGS method has global convergence.
