摘要
为了进一步提高GEP的函数自动建模的效率,提出了朴素基因表达式编程模型(Na ve GEP)NGEP;提出了原子基因片断的概念,以保护进化良好的基因片段;引入了基因嫁接操作,实现了NGEP原型。实验表明:NGEP在函数自动建模的收敛速度是标准GEP的2~4倍。
In order to improve the efficiency of GEP in function finding,a novel concept named Nave Gene Expression Programming(NGEP) and the concept of atomic gene fragments to preserve good genes were proposed.Gene-transplant was introduced and the prototype of NGEP system was implemented.Extensive experiments showed that the convergence speed of NGEP is as 2-4 times as that in the standard GEP.
