When processing the restrained conditions, we convert the restrained conditions into punish function and add it to fitness function which profits from the conventional method. We introduce the support vector machine to the selection operator, which increases the multiplicity of selection and increases the probability of the algorithm getting the overall optimal solution. Also, we use the adaptive probabilities of crossover and mutation in mixed GAs which enhances the efficiency of the algorithm. The result of tests about the system indicates that the improved genetic algorithm has more high convergence speed and better solution quality.

在生成初始种群时，不是简单的随机生成，而是用支持向量机对历史数据进行分类，用较优的一类历史数据作为初始种群；在约束条件的处理上，本文借鉴常规方法中的罚函数法，采用将约束条件作为罚函数包含到适应度评价中去的方法；在选择算子上，本文引入了支持向量机的方法，增加了选择的多样性，增加算法搜索到全局最优解的概率；同时针对交叉概率和变异概率在算法的前后期不同的情况，本文引入了Srinvivas等提出的动态自适应的方法，使得交叉概率和变异概率能够随着算法中个体的质量动态改变，提高算法的效率。

Thirdly, basing on the content of feature selection related in Weka which is an open source data mining tool, we propose a new feature selection algorithm based on rough set theory, which viewed the set of core features as the initial set, and define a symmetrical uncertainty measurement method as features correlation evaluating criterion.

进而，在剖析数据挖掘开源工具Weka系统中的属性选择实现的相关内容的基础之上，提出了一种新的属性选择算法，该算法以粗糙集合理论中的核集作为属性选择的初始集合，以对称不确定性作为属性评价方法，综合考虑了属性与类之间和属性与属性之间的相关性。
