The plane-width of graphs [PDF]
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.

Summary: 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 algorithm uses \(O(m)\) space and generates such graphs in \(O(1)\) time per graph on average without duplications.

Improved Bounds for Some Facially Constrained Colorings
A facial-parity edge-coloring of a 2-edge-connected plane graph is a facially-proper edge-coloring in which every face is incident with zero or an odd number of edges of each color. A facial-parity vertex-coloring of a 2-connected plane graph is a proper

The total face irregularity strength of some plane graphs
A face irregular total -labeling of a 2-connected plane graph is a labeling of vertices and edges such that their face-weights are pairwise distinct. The weight of a face under a labeling is the sum of the labels of all vertices and edges surrounding ...

Strong parity vertex coloring of plane graphs [PDF]
A strong parity vertex coloring of a 2-connected plane graph is a coloring of the vertices such that every face is incident with zero or an odd number of vertices of each color.

On the Hamiltonian Number of a Plane Graph
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 ...

We introduce a new type of graph drawing called "rook-drawing". A rook-drawing of a graph $G$ is obtained by placing the $n$ nodes of $G$ on the intersections of a regular grid, such that each row and column of the grid supports exactly one node. This paper focuses on rook-drawings of planar graphs. We first give a linear algorithm to compute a planar

Rook-Drawing for Plane Graphs [PDF]
Motivated by visualization of large graphs, we introduce a new type of graph drawing called "rook-drawing". A rook-drawing of a graph G is obtained by placing the n nodes of G on the intersections of a regular grid, such that each row and column of the grid supports exactly one node. This paper focuses on rook-drawings of planar graphs. We first give a
