Description
  • In this paper we deal with posets and graphs associated to them. We concentrate on so called cover-incomparability graphs. We prove that the C-I graph recognition problem is in general NP-complete. Then we present several classes of graphs (distance-hereditary graphs, Ptolemaic graphs, $k$-trees) for which the C-I graph recognition problem is polynomial.
