摘要
提出了一种基于信息系统的优化规则的提取方法,主要目的是提取信息系统中具有一定充要性的优化规则。首先,提出了充要强度并讨论了它的性质。其次,由于搜索空间的巨大和遗传算法的全局优化的特性,设计了使用遗传算法进行优化规则搜索的方法。最后,通过实验说明方法的有效性。
A new method extracting optimization rules based on information system was put forward. And this method aimed to extract certain optimization rules of necessity and sufficiency in information system. Firstly, strength of necessity and sufficiency and its feature were put forward and discussed. Secondly, for the massive characteristic of searching space and overall optimization of genetic algorithms, optimization rule searching method using genetic algorithms was designed. Lastly, the effectiveness of this method was verified through experiment.
