| 摘 要： | 应用遗传算法的基因表达式程序,对山东齐家沟金矿的岩石地球化学数据进行了函数发现的实验研究.结果表明:Au-Ag、Au-As、Au-Sb的GEP发现函数基本能反映训练样品元素之间的变化规律,Au-Ag、Au-As为正相关的非线性函数关系,Au-Sb为复杂的指数函数关系,且都能反映高异常值,说明遗传算法在地球化学元素评价中是有效的.

| Abstract: | The study aims to find function for rock geochemical data on Qijiaguo Gold Mine of Shandong by using gene expression programming (GEP) in genetic algorithm.It is shown that Au-Ag,Au-As,Au-Sb function of GEP finding can reflect variation of data-relation while Au-Ag and Au-As have non-line function.Au-Sb has complex exponent function.Genetic algorithm is helpful for relational appraise of geochemistry. |
