Complexity of $C_k$-coloring in hereditary classes of graphs
Witryna10 gru 2007 · A famous example of this type is the class of perfect graphs characterized recently in terms of the forbidden cycles of odd length at least 5 and their complements [13]. Assume now that F is a family of graph classes which is hereditary in the sense that with every class X it contains all subclasses of X. Witrynagraphs G and F, we say that G contains F if F is an induced subgraph of G. By F-free graphs we mean the class of graphs that do not contain F. Note that this class is … Witryna5 mar 2015 · We discover new hereditary classes of graphs that are minimal (with respect to set inclusion) of unbounded clique-width. The new examples include split permutation graphs and bichain graphs. Each of these classes is characterised by a finite list of minimal forbidden induced subgraphs. These, therefore, disprove a … shoot and scoot
