| 摘 要： | 本文构造了一个在多处理机上寻找用于求解非线性方程组的区间迭代法的安全初始区域的异步并行搜索算法,它能用于求非线性方程组的所有解。数值算例表明该算法具有较理想的加速比和效率。对该算法的安全判别准则进行变换后,也可用来寻找其它送代法的安全初始区域。

| Abstract: | This paper presents an asynchronous parallel search algorithm for finding the safe starting regions of interval iterative methods,which can be used in multiprocessors to find the all solutions of nonlinear equations.The results of numerical experiments show that the speed-up and the efficiency of this,algorithm are satisfactory.The algorithm can also be used to find the safe starting regions of othes iterative methods with the stopping criteria changed. |
