摘要
基于闭包的放大和最小性特点来处理离散数学中相关概念,梳理了离散数学中显性和隐性的一些闭包概念,如二元关系的闭包、强分图、子空间、和空间、生成子群等.试图在闭包的框架下将这些概念的教学格式化,操作过程标准化.同时,介绍了作者的教学方案和一些教学技巧,最后将关系传递闭包的思想应用到最短路径及一笔画问题等案例的算法设计中.
We make a thorough inquiry about the concepts in discrete mathematics based on the amplification and minimum features of the closure. We collected some explicit concepts and implicit concepts of closure from discrete mathematics such as closures of binary relation.strong part graph.subspace,sum subspaee,gener- ating subgroup and so on. Trying to format the teaching of these concepts and procedure standardization in the framework of the closure. At the same time, we introduce our teaching programs and techniques. Finally, the thinking of relationship transitive closure is applied to the algorithm design of the shortest path and Euler roads.
