分析了在求解方程的迭代过程中,算法中常用单一停止准则的不足,并给出了一些组合的停止准则,数值实验表明,这些停止准则是有效的.
This paper analyzes the deficiency of current stopping criterion of the iterative algorithm for root-finding problems, and presents some new united stopping criteria. Numerical experiments show that these stopping criteria are effective.
