To realize the model, Read linear code is used to code genetic individually. The tree-like individuals are replaced by decimal codes and the genetic operation is implemented by the operation of the linear code, which improve the computing efficiency.

同时在模型的实现上对遗传个体进行Read线性编码,用十进制编码来代替个体树,通过对编码的操作来实现各种遗传操作,极大地提高了程序运算效率。
