Evaluating a Weighted Graph Polynomial for Graphs of Bounded Tree-Width
نویسنده
چکیده
We show that for any k there is a polynomial time algorithm to evaluate the weighted graph polynomial U of any graph with tree-width at most k at any point. For a graph with n vertices, the algorithm requires O(akn 2k+3) arithmetical operations, where ak depends only on k.

A comparison of two approaches for polynomial time algorithms computing basic graph parameters
In this paper we compare and illustrate the algorithmic use of graphs of bounded treewidth and graphs of bounded clique-width. For this purpose we give polynomial time algorithms for computing the four basic graph parameters independence number, clique number, chromatic number, and clique covering number on a given tree structure of graphs of bounded tree-width and graphs of bounded clique-widt...
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 کاملCollective Tree Spanners in Graphs with Bounded Genus, Chordality, Tree-Width, or Clique-Width
In this paper we study collective additive tree spanners for special families of graphs including planar graphs, graphs with bounded genus, graphs with bounded tree-width, graphs with bounded cliquewidth, and graphs with bounded chordality. We say that a graph G = (V,E) admits a system of μ collective additive tree r-spanners if there is a system T (G) of at most μ spanning trees of G such that...
متن کاملThe Tutte Polynomial for Matroids of Bounded Branch-Width
It is a classical result of Jaeger, Vertigan and Welsh that evaluating the Tutte polynomial of a graph is #P -hard in all but few special points. On the other hand, several papers in past years have shown that the Tutte polynomial of a graph can be efficiently computed for graphs of bounded tree-width. In this paper we present a recursive formula computing the Tutte polynomial of a matroid M re...
متن کاملBounded Treewidth and Space-Efficient Linear Algebra
Motivated by a recent result of Elberfeld, Jakoby and Tantau[EJT10] showing that MSO properties are Logspace computable on graphs of bounded tree-width, we consider the complexity of computing the determinant of the adjacency matrix of a bounded tree-width graph and as our main result prove that it is in Logspace. It is important to notice that the determinant is neither an MSO-property nor cou...
