In sample data, we use the database of Taiwan Finance Database of Taiwan Economic Journal and collect 14,125 company's' finance data which include 153 default company's' data to study. We use these financial data to make Variance Inflation Factor test, and use the result of credit scoring model to make Kolmogorov–Smirnov test and Receiver Operating Characteristic check. Finally, the conclusions are listed as following

Firstly, the authors create various initial colonies and introduce quinary coding strategy to improve searching speed. Then, they adopt random selection mechanism without reimbursement to prevent premature convergence. Twopoint crossover and multipoint mutation are adopted to extend searching range of model space and to keep individual diversity.
首先,产生多样化的初始群体,引入五进制的编码策略提高搜索速度,然后采用无退还随机选择机制防止收敛早熟,采取两点交叉及多点变异方案以扩大模型空间的搜索范围和保持个体的多样性。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.
索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称;三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起,称之为挽歌体诗人或者史诗诗人,他们被称为诗人,似乎只是因为遵守格律写作,而非他们作品的模仿本质。
