【摘要】 对应用遗传算法解决病态方程问题进行了探讨。利用拟合法而不是通过法方程求解参数 ,从而避免了法方程系数求逆 ,使病态方程的解答有了较好的结果。通过模拟计算并和其他方法进行比较 ,证明该方法是可行的和有效的。更多还原

【Abstract】 Genetic algorithms(GA) is used for solving ill-conditioned equations in this paper, and its principle is introduced briefly. Some problems that should be considered when using GA to solve ill-conditioned equations are demonstrated. Two ill-conditioned equations,as examples,are solved by GA method, singular value decomposition method and generalized ridge estimate method. The results of the two examples show that GA method is effective.更多还原
