Abstract: Data mining is a hot research point in database area. In this paper, we discuss a new data mining algorithm based on genetic algorithm. It is designed for classified data. This algorithm uses a two-double and retractable structure, and emphasizes the distribution and diversity of the genes. It has good entire and local research ability.
