求解非线性方程的人口迁移算法

Population Migration Algorithm for Solving Nonlinear Equation

探讨用人口迁移算法求解非线性方程的方法,该方法把方程求解问题转化为函数优化问题。计算中不需要使用目标函数的导数信息,在MatLab语言环境下实现了该算法,数值实验结果表明该算法的有效性。

Discusses the method using a population migration algorithm to solve nonlinear equation. It transforms the problems into function optimization problems and the deribative of objective function is not used in the computation. The program is carried out under the environment of MatLab language. A large number of numerical experiments indicate that the population migration algorithm is a very effective algorithm for nonlinear equation.
