摘要(Abstract):

以生产实际数据或实验数据为基础,提出了科学发现经验公式的遗传规划方法。将经验公式用层次化的算法树来描述,算法树由组成经验公式的数学运算符和描述其工程问题的变量和常量构成。基于所获得的实际数据,从一系列随机生成的初始经验公式出发,运用生物生存竞争、适者生存的自然进化法则,对初始经验公式群进行类似于生物进化的复制、交换、变异等若干个结构改良操作,最终形成能真正、全面描述问题实质的经验公式。该方法排除了人的干预,具有很好的客观性和极大的通用性,可用于确定爆破工程中任何经验公式。
This paper puts forward a genetic programming method to find scientifically real experiential formulas based on production or experimental data.In this method,an experiential formula is described as a hieratical parse tree,which consists of mathematical operators needed by the formula,variables and constants representing the problem to be solved.Starting from a series of initial experiential formulas generate drandomly based on the structure of hieratical parse tree,the genetic programming method employs the creatures' evolution rule of struggle for existence and survival of the fittest in nature to improve structures of these experiential formulas by a way similar to creatures' reproduction,crossover,mutation and so on,and finds finally the best experiential formula which can describe completely the problem to be solved.This method rules out any disturbance from man,has the features of good objectiveness and highly universality and can determine any experiential formulas in blasting engineering.
