摘要
为了扩大现有研究的应用范围,基于max-min型模糊正则文法引入了max-*型模糊正则文法(其中*为特定t-模)的概念,讨论了max-*型模糊正则文法可以通过max-min型模糊正则文法在任意给定的逼近精度来逼近。研究表明,当t-模*满足一定的条件时,max-*型模糊正则文法与max-min型模糊正则文法在生成模糊语言能力方面是等价的。
To exentd the application fields of the present research,the concept of fuzzy regular grammar with max-＊ composition for some t-norn ＊ is given, which is basised on the study of fuzzy regular gram- mar with max-min composition. Then we discuss that a fuzzy regular grammar with max- ＊ composition can be approximated by some fuzzy regular grammar with max-min composition with any given accuracy. The research shows that fuzzy regular grammar with max- ＊ composition and fuzzy regular grammar with max-min composition are equivalent in the sense of generated of fuzzy language if ＊ satisfies some condition.
