关于题意

Posted by 3corc at 2009-01-24 22:49:53 on Problem 3241
 and in each group, one object is at most X resemble to another object in the same group, i.e, for every object i, if i is not the only member of the group, then there exists one object j (i ≠ j) in the same group that satisfies dij ≤ X
i.e前面是说在一个组里,一个对象和另一个对象的关联最多是x,
i.e的后面是说如果一个组里有>1个对象,那么对于组里任意一个对象i,在同一组里存在一个对象j(i!=j),使得对象j满足dij<=x
这两个说法是矛盾的。
谁能给我讲一下,正确的理解。
最好结合例子分析一下,谢谢各位了
