1966 年, 艾迪續證明任何有 n 點簡單圖的邊集合, 其中無孤立點, 均能被最多 ⌊n2/4⌋ 團所覆蓋, 幾十年後 McGuinness 證明任何一個貪婪團分割均為這樣的一個分割, 這篇論文證明與其對應的集合表示也不會用到超過 ⌊n2/4⌋ 元素
In 1966 Erd¨os et al. [8] proved that the edge set of any simple graph G with n vertices, no one of which is isolated vertex, can be partitioned using
at most ⌊n2/4⌋ cliques. A couple of tens of years behind McGuinness
proved that any greedy clique partition is such a partition.
In this paper we prove that any set representation corresponding to it wouldn't use more than ⌊n2/4⌋ element.
