摘要
以品位实测数据为基础，提出了科学发现矿体真实品位估计公式的遗传规划方法。该方法根据自然界生物生存竞争、适者生存的进化法则，对众多随机生成的品位估计公式进行类似于生物进化时发生的复制、交换、变异等若干个结构改良操作，淘汰极不合理的估计公式，改良较合理的估计公式，最后优选出能真实、全面描述矿体品位分布的品位估计公式。该方法完全排除了人为的参数预给定，具有很好的客观性、通用性和精确性。
A Genetic programming method to find the true formula of grade estimation scientifically was put forward based on the actual data of grade control points. The structures of a series of estimating formulas generated randomly have been improved by a way similar to creatures′ reproduction,crossover,mutation and so on,according to the creatures′ evolution rule of struggle for existence and survival of the fittest in nature.The worst formulas were deleted and the suitable formulas have been improved.Finally,the best formula which can completely describe the grade distribution of orebody was found out.The predefined parameters were obviated.This method has good objectiveness,general utility and accurateness.
