冗余规则(Redundancy Rule)是生成语法中的一条规则。 在词库（lexicon）中只标注出词项与众不同的词汇信息
Furthermore, it realizes the compression of the behavior rule by deleting the redundant rule, which can escalate the intrusion detection phase as the normal behavior rule reduces to a fairly small number.
此外,实现了行为规则的简化,删除了规则库中的冗余规则,行为规则简化使规则库中的规则维持一个较小的数量,有利于加速入侵检测过程。

Rule filtering is used to delete redundant rule and only the most general, and essential rules are kept.
另外，在优化后的种群中存在一些冗余规则，考虑到规则集的简洁性，提出了一种规则提取方法。
In addition, some redundant rules exist in the optimized population, considering the conciseness of the final rule set, so this paper presents a rule extraction method.
