摘要
以Powell方法的Zangwill修改为基础进行改进可以得到很多有效的算法。本文的目的在于证明Powell方法另一类修改的二阶收敛性质。
In this paper, a new algorithm for function minimization is given and studied. The final result is that if the object function possesses such good properties as uniform convex and suitable smoothness, then the rate of convergence of the algorithm is quadratic.
