摘要
通过改变遗传规划算法在生成初始群体时的方法,调整变异概率,修正适应度函数,对遗传规划算法进行改进,使生成的初始群体具有良好的性能;并通过两个函数进行符号验证,说明改进后的方法是有效可行的。
A new method changing genetic programming algorithm on generating initial population is used to adjust variation probability,to modify fitness function and to revise genetic programming algorithm,in order to make generated initial population possess good performance.Two functions are used to conduct symbol verification,which indicate that the improved method is effective and feasible.
