Balanced separator
웹2024년 1월 1일 · Results and paper organization. In this paper we continue the idea of geometric separators and show that a balanced separator always exists, even if we constrain the separator to be a line (see Fig. 1).Given a set of n unit disks with m pairs of intersecting disks, we show that a line 2/3-separator of size O ((m + n) log n) can be … 웹2006년 5월 21일 · Download Citation Finding small balanced separators Let G be an n-vertex graph that has a vertex separator of size k that partitions the graph into connected components of size smaller than ...
