摘要:将求解单调非线性方程组的CGD算法和MPRP算法的下降方向进行凸组合,构造出新的下降方向,从而提出新的算法,并给出新算法的全局收敛性定理.通过数值实验比较新算法与CGD算法和MPRP算法的结果,可知新算法优于原算法.

关键词: MPRP算法, CGD算法, 凸组合, 单调非线性方程组, 全局收敛性

Abstract: In this paper the authors convexly combine the the descent directions of the CGD algorithm and the MPRP algorithm for solving the monotone nonlinear equations,construct the new descent direction and give the new algorithm,and give the globally convergent theorem of the new algorithm.At last the authors compare the algorithms through the numerical experiments and  find that the new algorithm is better than the original algorithms.

Key words: MPRP algorithm, CGD algorithm, convex combination, monotone nonlinear equations, global convergence
