| 摘 要： | 大规模病态线性方程组的求解是相当困难的。本文尝试使用遗传算法求解大规模病态线性方程组,采用了改善方程组病态程度的预处理及多种杂交手段相结合改善遗传算法搜索性能两项措施,结果表明遗传算法求解大规模病态方程组是可行有效的。

| Abstract: | Solving large scale ill-conditioned linear systems of equation is very difficult.This paper is trying to use genetic algorithms to solve large scale ill-conditioned linear systems of equation.Equalization of the equations is used to decrease the morbidity degree of the linear systems of equation,and several kinds of crossover operators are adopted to improve the search ability of genetic algorithms.The experimental results show that genetic algorithms could effectively sove large scale ill-conditioned linear systems of equation. |
