saor meaning in English

绍

In chapter 2 . i propose a new type of preconditioned conjugate gradient method , which is called saor - al - pcg in brief
第二章提出了一种新的预条件共轭梯度法saor - al - pcg 。
The preconditioner m is derived on the base of saor and the alternating method . then we use conjugate gradient method to solve the preconditioned system max = mb
这种方法基于saor迭代法以及交错法，构造了预条件子m ，然后利用共轭梯度法来求解预条件方程max = mb 。
In chapter 4 , some examples are given to illustrate that the convergence of saor - al - pcg method is better than the classical iterative method ( such as jacobi . gauss ? seidel . sor ) and the traditional cg method as well as ssor - pcg
第四章用实例证明了这种预条件共轭梯度法的收敛速度比古典的迭代法(如jacobi ， gs ， sor )和传统的cg以及ssor - pcg要快一些。
