Application of genetic algorithm in data mining has been studied . based on gene hypothesis gene dynamic sort method has been brought forward . its feature is component of genes can become longer and better gene component and because of dynamic sort , good gene component can be kept effectively 在分類規(guī)則提取系統(tǒng)中,為了更好地提高算法的尋優(yōu)和保優(yōu)能力,提出了基因動態(tài)排序方法,即把各基因位按重要性大小進行排序,在此基礎上再進行交叉操作。
