摘要
n元高次方程根的个数求解常因问题的规模过大而使通常的算法时间复杂度过高。主要介绍了基于分治策略的二分思想来降低该问题的时间复杂度,并利用哈希技术和线性冲突解决方法进一步提高求解n元高次方程根个数的算法效率。
The seeking for roots of n - members hyper- polynomial equation has large time complexity due to the size of n . In this paper, the efficiency of algorithm is improved by operating of binary based on the strategy of divide and conquer as well as using the Hash table and the linear method to resolve the conflicts.
