closure finite

In this paper, strong close set of set of temporal types, finite closure of attribution sets, finite dependency base of attribution sets based on a certain temporal type and finite dependency base of attribution sets are introduced; the algorithm of finite closure and finite dependency base of attribution sets and the proof for its termination and correction are given.

本文定义了时态类型集的强封闭集、属性集的有限闭包、属性集在给定时态类型上的有限依赖基、属性集的有限依赖基等概念。

Thus, in this paper, strong close set of set of temporal types, finite closure of attribution sets, finite dependency base of attribution sets based on a certain temporal type, finite de.

由于成员籍问题的解决对设计有效的模式分解算法必不可少,由此定义了时态类型集的强封闭集、属性集的有限闭包、属性集在给定时态类型上的有限依赖基、属性集的有限依赖基及特殊有限依赖基等概念,给出了求属性集的有限闭包、有限依赖基和特殊有限依赖基、时态混合集成员籍问题的算法,并对算法的可终止性、正确性进行了证明,对时间复杂性进行了分析。
