In this paper, we propose a Dai–Liao (DL) conjugate gradient method for solving large-scale system of nonlinear equations. The method incorporates an extended secant equation developed from modified secant equations proposed by Zhang et al. (J Optim Theory Appl 102(1):147–157, 1999) and Wei et al. (Appl Math Comput 175(2):1156–1188, 2006) in the DL approach. It is shown that the proposed scheme satisfies the sufficient descent condition. The global convergence of the method is established under mild conditions, and computational experiments on some benchmark test problems show that the method is efficient and robust.

修正割线方程的Dai-Liao共轭梯度法求解非线性方程组

在本文中,我们提出了一种Dai-Liao(DL)共轭梯度法来求解大型非线性方程组。该方法结合了一个扩展的割线方程,该割线方程是由张等人提出的修正割线方程开发的。(J Optim Theory Appl 102(1):147-157,1999)和Wei等。(DL方法中的应用数学运算(Appl Math Comput 175(2):1156-1188,2006))。结果表明,所提出的方案满足充分的下降条件。该方法的全局收敛性是在温和条件下建立的,并且对一些基准测试问题的计算实验表明该方法是有效且稳健的。
