Gene-Expression Programming

Gene Expression Programming (GEP) is a powerful evolutionary method derived from Genetic Programming (GP) for model learning and knowledge discovery. However, when dealing with complex problems, its genotype under Karva notation does not allow hierarchical composition of the solution, which impairs the efficiency of the algorithm.

We propose a new representation scheme based on prefix notation that overcomes the original GEP's drawbacks. The resulted algorithm is called Prefix GEP (P-GEP). The major advantages with P-GEP include the natural hierarchy in forming the solutions and more protective genetic operations for substructure components. An artificial symbolic regression problem and a set of benchmark classification problems from UCI machine learning repository have been tested to demonstrate the applicability of P-GEP. The results show that P-GEP follows a faster fitness convergence curve and the rules generated from P-GEP consistently achieve better average classification accuracy compared with GEP。

谢谢禅师。看过一些相关的资料（国内翻译叫基因表达式编程），感觉在数据比较大的情况下，其进化的计算量会非常巨大。

要想让计算机自己写个程序或发现一个什么牛顿定律，还是应当花些时间的吧。否则那科学家也太好当了。:)

这个太强，要慢慢消化，有多少人使用这个方法？
