摘要
基于非线性方程组的牛顿-全局松弛并行多分裂方法的思想,将求解线性方程组的松弛矩阵多分裂USAOR迭代法推广至求解非线性方程组,研究了牛顿-松弛非定常多分裂多参数TOR迭代法,建立了局部收敛性定理,估计了收敛速度。
Based on the ideas of Newton-global relaxation parallel multiple splitting method,this paper extends the applicable equation type of relaxed matrix multisplitting USAOR iterative method from linear systems to nonlinear systems and presents Newton-relaxed nonstationary multisplitting multi-parameters TOR method for nonlinear equations.Moreover,the convergence of this methods are studied,the convergence theorems are set up and the rate of convergence is estimated.
