中文摘要: 传统 GEP(Gene Expression Programming)算法存在局部收敛方面的缺陷,为了解决这一问题,提出了可以使进化快速跳出局部最优的VPS-GEP(Various Population Strategy GEP)算法,证明了在概率意义上GEP平均每代进化所耗时间与群体规模成正比,用两个标准测试函数和一个标准测试数据集测试了VPS-GEP算法的函数挖掘能力和效率。实验表明,VPS-GEP算法可以减少进化停滞代数55%以上。
Abstract:The traditional Gene Expression Programming(GEP) has the deficiency of local optimization. In order to solve this problem, VPS-GEP(Various Population Strategy GEP), an algorithm for evolution skipping from local optimization fast,was proposed.It was proved that the time for per generation evolution increases with the size of population under probability sense. The ability of mining function and efficiency of VPS-GEP was tested by two standard test functions and one standard dataset. The experiments showed that VPS-GEP algorithm decreases the generation stagnancy over 55%.
