摘要
Li-Fukushima[3]提出了一种修正的BFGS方法MBFGS算法.本文研究MBFGS算法中迭代矩阵的收敛性.我们证明在一定条件下,MBFGS算法用于求解严格凸二次函数极小值时产生的迭代矩阵序列是收敛的.
Li and Fukushima [3 ] proposed a modified BFGS method-MBFGS method. In this paper, we study the convergence property of the sequence of iteration matrices generated by the MBFGS method. We show that under appropriate conditions, the matrix sequence is convergent if the objective function is a strictly convex quadratic function.
