Title: | Maximizing edge-ratio is NP-complete | Journal: | Discrete Applied Mathematics | Volume: | 159 | Issue: | 18 | First page: | 2276 | Last page: | 2280 | Issue Date: | 6-Dec-2011 | Rank: | M22 | ISSN: | 0166-218X | DOI: | 10.1016/j.dam.2011.07.016 | Abstract: | Given a graph G and a bipartition of its vertices, the edge-ratio is the minimum for both classes so defined of their number of internal edges divided by their number of cut edges. We prove that maximizing edge-ratio is NP-complete. |
