Strong-mixed searching and pathwidth [PDF]
In this paper, we propose a new search model, called strong-mixed search, which is a generalization of the mixed search. We show that the strong-mixed search number of a graph equals the pathwidth of the graph. We also describe relationships between the strong-mixed search number and other search numbers.

Graph and String Parameters: Connections Between Pathwidth, Cutwidth and the Locality Number [PDF]
We investigate the locality number, a recently introduced structural parameter for strings (with applications in pattern matching with variables), and its connection to two important graph-parameters, cutwidth and pathwidth. These connections allow us to show that computing the locality number is NP-hard, but fixed-parameter tractable, if parameterised

Induced subgraphs and tree decompositions XVIII. Obstructions to bounded pathwidth [PDF]
The pathwidth of a graph $G$ is the smallest $w\in \mathbb{N}$ such that $G$ can be constructed from a sequence of graphs, each on at most $w+1$ vertices, by gluing them together in a linear fashion. We provide a full classification of the unavoidable induced subgraphs of graphs with large pathwidth.

Approximation Algorithms for Digraph Width Parameters [PDF]
Several problems that are NP-hard on general graphs are efficiently solvable on graphs with bounded treewidth. Efforts have been made to generalize treewidth and the related notion of pathwidth to digraphs. Directed treewidth, DAG-width and Kelly-width are some such notions which generalize treewidth, whereas directed pathwidth generalizes pathwidth ...
