We consider three different, natural ways of forbidding H as an induced subgraph in G. We refer to the surveys of Gurski [19] and Kamiński, Lozin and Milanič [21] for an in-depth study of the properties of clique-width. We say that a class of graphs has bounded clique-width if every graph from the class has clique-width at most c for some constant c. As many NP-hard graph problems can be solved in polynomial time on graph classes of bounded cliquewidth [13, 22, 27, 28] , it is natural to determine whether a certain graph class has An extended abstract of this paper appeared in the proceedings of CO-COON 2014 [17].
