摘要:
The decision problem MaxCut is known to be NP-complete since the seventies, but only recently its restriction to interval graphs has been announced to be hard by Adhikary, Bose, Mukherjee, and Roy. Building on their proof, in this paper we prove that the MaxCut problem is NP-complete on permutation graphs. This settles a long-standing open problem that appeared in the 1985 column of the Ongoing Guide to NP-completeness by David S. Johnson, and is the first NP-hardness entry for permutation graphs in such column.
