摘要：
A graph G is called CIS if each maximal clique intersects each maximal stable set in G and is called almost CIS if it has a unique disjoint pair (C, S) consisting of a maximal clique C and a maximal stable set S. While it is still unknown if there exists a good structural characterization of all CIS graphs, in this note we prove the following Andrade-Boros-Gurvich conjecture: A graph is almost CIS if and only if it is a split graph with a unique split partition.
