On the parameterized complexity of computing tree-partitions [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science
We study the parameterized complexity of computing the tree-partition-width, a graph parameter equivalent to treewidth on graphs of bounded maximum degree.

Deciding Clique-Width for Graphs of Bounded Tree-Width

open access: yesJournal of Graph Algorithms and Applications, 2003
We show that there exists a linear time algorithm for deciding whether a graph of bounded tree-width has clique-width k for some fixed integer k.

On the Complexity of Embedding in Graph Products

open access: yesComputing in Geometry and Topology
Graph embedding, especially as a subgraph of a grid, is an old topic in VLSI design and graph drawing. In this paper, we investigate related questions concerning the complexity of embedding a graph G in a host graph that is the strong product of a path ...

The algorithmic theory of treewidth

open access: yesElectronic Notes in Discrete Mathematics, 2000
Abstract Treewidth is a graph measure with several applications. In this abstract, it is discussed that many otherwise intractable problems become polynomial or linear time solvable when restricted to graphs of bounded treewidth, and some other algorithmic results that use treewidth (e.g., applied to planar graphs) are discussed.

The Treewidth of Java Programs

open access: yes, 2002
Intuitively, the treewidth of a graph $G$ measures how close $G$ is to being a tree. The lower the treewidth, the faster we can solve various optimization problems on $G$, by dynamic programming along the tree structure. In the paper M.Thorup, All Structured |Programs have Small Tree-Width and Good Register Allocation [8] it is shown that the control ...
