Suppose R is a binary relation on a set S. The reflexive closure of R is the smallest reflexive relation R' that contains R. (Smallest in the sense that if R'' is some other reflexive relation that contains R, R' is a subset of R'') Supposed we are given a relation R on a set...

On a more technical level, in computer science, the term "transitive closure" refers to the extension of a relation to include all pairs that can be reached through a series of intermediate relations. This concept is crucial for understanding the reachability and connectivity in data ...
摘要: This paper introduces the three kinds of methods to obtain the transitive closure of binary relation on a finiteset. These three kinds of algorithms all reduce operational quantity efficiently. 关键词: relation matrix binary relation transitive closure 被引量: 3 年份: 2006 收藏...
