The interval count of interval graphs and orders: a short survey

Journal of the Brazilian Computer Society volume 18, pages 103–112 (2012)Cite this article

Abstract

The interval count problem determines the smallest number of interval lengths needed in order to represent an interval model of a given interval graph or interval order. Despite the large number of studies about interval graphs and interval orders, surprisingly only a few results on the interval count problem are known. In this work, we provide a short survey about the interval count and related problems. a graph and the number of its maximal cliques.
