Parameters identification of complex functions based on gene expression programming

在介绍了基因表达式程序设计方法的基础上,采用基因表达式程序设计建立了复杂函数参数识别的模型,给出了算法结构与算法程序流程,并利用基因表达式程序设计方法进行未知函数拟合的实验,定义合适的终止条件,得到精确的预测结果。实验结果表明,此方法具有很高的预测精度,明显优于传统方法。最后指出该方法只需要提供足够的实验或实验数据,知道目标函数,就可以达到准确预测的目的,因而可以广泛应用于复杂函数拟合中,具有广阔的应用前景。

Gene expression programming （GEP） is introduced. GEP is applied in the modeling of parameters identification of complex functions, the algorithm of the relevant model is also presented. By using the appropriate termination function, the accurately results is got by the GEP. The simulation results show that the model found by GEP is more accurate than the one found by traditional way. The algorithm, predict accurately based on few experienced data, can be widely used in many field.
