Listing All Plane Graphs

open access: yesJournal of Graph Algorithms and Applications, 2009
In this paper we give a simple algorithm to generate all connected rooted plane graphs with at most m edges. A rooted" plane graph is a plane graph with one designated (directed) edge on the outer face.

The plane-width of graphs [PDF]

open access: yesJournal of Graph Theory, 2011
Map vertices of a graph to (not necessarily distinct) points of the plane so that two adjacent vertices are mapped at least a unit distance apart. The plane-width of a graph is the minimum diameter of the image of the vertex set over all such mappings.

On the Hamiltonian Number of a Plane Graph [PDF]

open access: yesDiscussiones Mathematicae Graph Theory, 2019
The Hamiltonian number of a connected graph is the minimum of the lengths of the closed spanning walks in the graph. In 1968, Grinberg published a necessary condition for the existence of a Hamiltonian cycle in a plane graph, formulated in terms of the ...

On Visibility Representation of Plane Graphs [PDF]

open access: yes, 2004
In a visibility representation (VR for short) of a plane graph G, each vertex of G is represented by a horizontal line segment such that the line segments representing any two adjacent vertices of G are joined by a vertical line segment. Rosenstiehl and Tarjan [11], Tamassia and Tollis [14] independently gave linear time VR algorithms for 2-connected ...

Splitting Plane Graphs to Outerplanarity

open access: yesJournal of Graph Algorithms and Applications, 2023
Vertex splitting replaces a vertex by two copies and partitions its incident edges amongst the copies. This problem has been studied as a graph editing operation to achieve desired properties with as few splits as possible, most often planarity, for ...

On the Plane-Width of Graphs [PDF]

open access: yesElectronic Notes in Discrete Mathematics, 2009
Map vertices of a graph to (not necessarily distinct) points of the plane so that two adjacent vertices are mapped at least a unit distance apart. The plane-width of a graph is the minimum diameter of the image of the vertex set over all such mappings.

Folding Equilateral Plane Graphs [PDF]

open access: yesInternational Journal of Computational Geometry & Applications, 2011
We consider two types of folding applied to equilateral plane graph linkages. First, under continuous folding motions, we show how to reconfigure any linear equilateral tree (lying on a line) into a canonical configuration. By contrast, it is known that such reconfiguration is not always possible for linear (nonequilateral) trees and for (nonlinear ...

Graph polynomials and paintability of plane graphs

open access: yesDiscrete Applied Mathematics, 2022
There exists a variety of coloring problems for plane graphs, involving vertices, edges, and faces in all possible combinations. For instance, in the \emph{entire coloring} of a plane graph we are to color these three sets so that any pair of adjacent or incident elements get different colors.
