抽屉原则与自由差集
Practical application of the drawer principle & free difference set
-
摘要: 运用抽屉原则的一般形式和整数集合中的自由差集能够解决一类组合理论中的一些实际问题.Abstract: Both the general form of the drawer principle and the free difference set of integral sets can be applied to solve some practical problems concerning combinatorial theory.In this paper,the writer would like to illustrate the relationship between the drawer principle and the free difference sets by demonstrating some typical examples so as to make it more or less significant to the combinatorial theory.
