摘　　要：探讨了用模拟退火算法求解非线性方程及方程组的方法,该方法把方程组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M atlab环境下实现了该算法,数值实验结果表明了该算法的有效性。The method using a Simulated Annealing Algorithm to solve nonlinear equations and system problems is discussed in this paper. It transforms the problems into function optimization problems and the derivative of objective function is not used in the computation. The program is carried out under the environment of Matlab. A large number of numerical experiments indicate that the Simulated Annealing Algorithm is a very effective algorithm for nonlinear system.
