چکیده
We show that a set of graphs has bounded tree-width or bounded path-width if and only if the corresponding set of line graphs has bounded clique-width or bounded linear clique-width, respectively. This relationship implies some interesting algorithmic properties and re-proves already known results in a very simpleway. It also shows that theminimization problem forNLC-width isNP-complete. © 2007 Elsevier B.V. All rights reserved.

Minimal forbidden induced subgraphs of graphs of bounded clique-width and bounded linear clique-width
In the study of full bubble model graphs of bounded clique-width and bounded linear clique-width, we determined complete sets of forbidden induced subgraphs, that are minimal in the class of full bubble model graphs. In this note, we show that (almost all of) these graphs are minimal in the class of all graphs. As a corollary, we can give sets of minimal forbidden induced subgraphs for graphs o...
متن کاملPolynomial-time Algorithm for Isomorphism of Graphs with Clique-width at most 3
The clique-width is a measure of complexity of decomposing graphs into certain tree-like structures. The class of graphs with bounded clique-width contains bounded tree-width graphs. While there are many results on the graph isomorphism problem for bounded treewidth graphs, very little is known about isomorphism of bounded cliquewidth graphs. We give the first polynomial-time graph isomorphism ...
متن کاملBounded Clique-Width of ($S_{1, 2, 2}$, Triangle)-Free Graphs
If a graph has no induced subgraph isomorphic to H1 or H2 then it is said to be (H1, H2)-free. Dabrowski and Paulusma found 13 open cases for the question whether the clique-width of (H1, H2)-free graphs is bounded. One of them is the class of (S1,2,2,triangle)-free graphs. In this paper we show that these graphs have bounded clique-width. Thus, also (P1+2P2,triangle)-free graphs have bounded c...
متن کاملModel Counting for Formulas of Bounded Clique-Width
We show that #SAT is polynomial-time tractable for classes of CNF formulas whose incidence graphs have bounded symmetric clique-width (or bounded clique-width, or bounded rank-width). This result strictly generalizes polynomial-time tractability results for classes of formulas with signed incidence graphs of bounded clique-width and classes of formulas with incidence graphs of bounded modular t...
متن کاملClique-width and tree-width of sparse graphs
Tree-width and clique-width are two important graph complexity measures that serve as parameters in many fixed-parameter tractable (FPT) algorithms. The same classes of sparse graphs, in particular of planar graphs and of graphs of bounded degree have bounded tree-width and bounded clique-width. We prove that, for sparse graphs, clique-width is polynomially bounded in terms of tree-width. For p...
