| 摘 要： | 填充函数法是求解全局优化问题的有效方法之一，针对无约束优化问题，提出一个新的连续可微的无参数填充函数，证明其相关性质并给出相应的算法，数值实验结果表明该算法是有效可行的。同时用此填充函数对切削温度实验数据这一拟合实例进行求解，与已有的最小二乘法和遗传算法的求解结果相比较，拟合效果较好。

| Abstract: | The filled function method is one of the effective methods to solve the global optimization problem.In this paper,a new continuous and differentiable nonparameter filled function is proposed for the unconstrained optimization problem.The related properties of the filled function are proved and the corresponding algorithm is designed.By comparing with the numerical experimental results in previous literature,it is shown that the proposed filled function algorithm is effective and feasible.Then,the proposed filled function method is used to solve the data fitting example of cutting temperature experimental data,compared with the existing least squares method and genetic algorithm,the fitting effect is better. |
