On the Pathwidth of Planar Graphs [PDF]

open access: yes, 2006
Fomin and Thilikos in [5] conjectured that there is a constant $c$ such that, for every $2$-connected planar graph $G$, {pw}(G^*) \leq 2\text{pw}(G)+c$ (the same question was asked simutaneously by Coudert, Huc and Sereni in [4]). By the results of Boedlander and Fomin [2] this holds for every outerplanar graph and actually is tight by Coudert, Huc and

Effect of Steaming as Postprocessing Method on Rice Flour and Jaggery 3D Printed Construct

open access: yesJournal of Food Quality, Volume 2022, Issue 1, 2022., 2022
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 ...

Order Reconfiguration under Width Constraints

open access: yesJournal of Graph Algorithms and Applications, 2023
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 ...

Constrained Connectivity in Bounded X-Width Multi-Interface Networks

open access: yesAlgorithms, 2020
As technology advances and the spreading of wireless devices grows, the establishment of interconnection networks is becoming crucial. Main activities that involve most of the people concern retrieving and sharing information from everywhere.

Exclusive Graph Searching vs. Pathwidth [PDF]

open access: yes, 2014
In Graph Searching, a team of searchers aims at capturing an invisible fugitive moving arbitrarily fast in a graph. Equivalently, the searchers try to clear a contaminated network.The problem is to compute the minimum number of searchers required to ...

Pathwidth vs Cocircumference [PDF]

open access: yesSIAM Journal on Discrete Mathematics
The {\em circumference} of a graph $G$ with at least one cycle is the length of a longest cycle in $G$. A classic result of Birmelé (2003) states that the treewidth of $G$ is at most its circumference minus $1$. In case $G$ is $2$-connected, this upper bound also holds for the pathwidth of $G$; in fact, even the treedepth of $G$ is upper bounded by its

Crossing Number for Graphs with Bounded Pathwidth [PDF]

open access: yesAlgorithmica, 2020
The crossing number is the smallest number of pairwise edge-crossings when drawing a graph into the plane. There are only very few graph classes for which the exact crossing number is known or for which there at least exist constant approximation ratios.

A General Reduction Theorem with Applications to Pathwidth and the Complexity of MAX 2-CSP [PDF]

open access: yes, 2015
We prove a general reduction theorem which allows us to extend bounds for certain graph parameters on cubic graphs to bounds for general graphs taking into account the individual vertex degrees.

Drawing Halin-graphs with small height

open access: yesJournal of Graph Algorithms and Applications, 2022
In this paper, we study how to draw Halin-graphs, i.e., planar graphs that consist of a tree $T$ and a cycle among the leaves of that tree. Based on tree-drawing algorithms and the pathwidth $pw(T) $, a well-known graph parameter, we find poly-line ...
