先随机找寻一个合理的初始划分，然后试探将样本从一个群搬到另一个群，如果某次搬动能使准则函数值得到改进的话，则继续搬运，否则废除本次搬运，再继续其他搬运。(Randomly and find a reasonable initial division, and then test the sample from a group of moving to another group, if a move can make the criterion function is worth to improve, it continues to handling, otherwise the abolition of the handling, continue to other handling.)
