Separating layered treewidth and row treewidth [PDF]
Layered treewidth and row treewidth are recently introduced graph parameters that have been key ingredients in the solution of several well-known open problems.

New Algorithms for Mixed Dominating Set [PDF]
A mixed dominating set is a collection of vertices and edges that dominates all vertices and edges of a graph. We study the complexity of exact and parameterized algorithms for \textsc{Mixed Dominating Set}, resolving some open questions.

Two Results on Layered Pathwidth and Linear Layouts
Layered pathwidth is a new graph parameter studied by Bannister et al. (2015). In this paper we present two new results relating layered pathwidth to two types of linear layouts. Our first result shows that, for any graph $G$, the stack number of $G$ is

Classes of graphs with restricted interval models [PDF]
We introduce q-proper interval graphs as interval graphs with interval models in which no interval is properly contained in more than q other intervals, and also provide a forbidden induced subgraph characterization of this class of graphs. We initiate a

Recent Advances in Positive-Instance Driven Graph Searching
Research on the similarity of a graph to being a tree—called the treewidth of the graph—has seen an enormous rise within the last decade, but a practically fast algorithm for this task has been discovered only recently by Tamaki (ESA 2017).

A new two-variable generalization of the chromatic polynomial [PDF]
We present a two-variable polynomial, which simultaneously generalizes the chromatic polynomial, the independence polynomial, and the matching polynomial of a graph.

Order Reconfiguration under Width Constraints
In this work, we consider the following order reconfiguration problem: Given a graph $G$ together with linear orders $\omega$ and $\omega'$ of the vertices of $G$, can one transform $\omega$ into $\omega'$ by a sequence of swaps of adjacent elements in ...

Effect of Steaming as Postprocessing Method on Rice Flour and Jaggery 3D Printed Construct
In this study, the 3D printing of a traditional South Indian snack, “sweet pidikollukattai” has been attempted. The mixing properties of the rice flour used and thermal characteristics of the paste (rice flour, jaggery, and water) have been reported. The traditional form of the product (control) was compared with the 3D printed product, which has been ...

On the Pathwidth of Hyperbolic 3-Manifolds
According to Mostow's celebrated rigidity theorem, the geometry of closed hyperbolic 3-manifolds is already determined by their topology. In particular, the volume of such manifolds is a topological invariant and, as such, has been subject of ...
