Three new techniques for knowledge discover by gene expression programming— transgene,overlapped gene expression and backtracking evolution
Zhong Yi-xiao · Jisuanji gongcheng · 2005
Three new technologies ware introduced by the authors in the past year,i.e.:(a) TranGene technique.By injection gene segment,it guides the evolution direction,controls knowledge discover process.(b) Overlapped gene expression.It borrows the idea of overlap gene expression from biological study,introduces overlapped gene expression,and saves space for gene expression.(c) Backtracking evolution.It comes from atavism in biology and proposes the concept of backtracking GEP algorithms,designing geometric proportion increased checkpoint sequence and accelerated increased checkpoint sequence to restrict the backtracking process. Experiments show that all three techniques respectively boost the performance of GEP by one or two magnitudes.
