摘要
本文提出了一个新的无约束最优化算法——修正DFP变尺度算法,该算法是在DFP方法的基础上修正迭代矩阵,以保证迭代矩阵的正定性,并且证明了新算法具有很好的二次终结性。
In this arficle a new method has been proposed-a updaaled DFP va -riable matrix algorithrvs. This method wpdafes iterance matrix on the basie ofDFP method so as to guarantee the definife of the iieratie matrix. It also proves that the new method has a good quadratie terminal qroqerty. Key Words iteratnce matrix. iterative directoon , quadratic terminal property.
