求翻译：基因表达式编程在语法上将个体先编码成固定长度的线性串，在语义上表示成形状、大小都不同的非线性实体，从而实现了利用简单编码解决复杂的问题，融合了GA和GP的优点，与传统的进化方法相比，效率提高了2~4个数量级是什么意思？

Gene expression programming in syntax will be self-employed to be encoded into a fixed-length of the linear string, the semantics, expressed as a size, shape, different non-linear entities in order to achieve the use of simple coding solutions to complex problems, and integration with GA GP and the

The gene expression programming the individual codes the fixed length first in grammar general the linear string, expresses the shape, the size all different non-linear entity in the semantics, thus has realized the use simple code solution complex question, fused GA and the GP merit, compares with

Individuals on the syntax encoding gene expression programming as linear, fixed-length strings, are semantically expressed as nonlinear entity has a different shape, size, and implemented using simple coding solution to complex problems, combining the advantages of GA and GP, compared with the tradi
