CYCLIC PROPERTIES OF TRIANGULAR GRID GRAPHS [PDF]

open access: yesIFAC Proceedings Volumes, 2006
Abstract It is known that all 2-connected, linearly convex triangular grid graphs, with only one exception, are hamiltonian (Reay and Zamfirescu, 2000). In the paper, it is shown that this result holds for a wider class of connected, locally connected triangular grid graphs and, with more exceptions, even for some general class of graphs.

Applying Infinite Petri Nets to the Cybersecurity of Intelligent Networks, Grids and Clouds

open access: yesApplied Sciences, 2021
Correctness of networking protocols represents the principal requirement of cybersecurity. Correctness of protocols is established via the procedures of their verification. A classical communication system includes a pair of interacting systems.

On the Number of Shortest Weighted Paths in a Triangular Grid

open access: yesMathematics, 2020
Counting the number of shortest paths in various graphs is an important and interesting combinatorial problem, especially in weighted graphs with various applications. We consider a specific infinite graph here, namely the honeycomb grid. Changing to its

Probabilistic Distributed Algorithm for Uniform Election in Triangular Grid Graphs [PDF]

open access: yesInternational Journal of Advanced Computer Science and Applications, 2013
Probabilistic algorithms are designed to handle problems that do not admit deterministic effective solutions.In the case of the election problem, many algorithms are available and applicable under appropriate assumptions, for example: the uniform election in trees, k-trees and polyominoids.In this paper, first, we introduce a probabilistic algorithm ...

3/2 Firefighters are not enough [PDF]

open access: yes, 2010
The firefighter problem is a monotone dynamic process in graphs that can be viewed as modeling the use of a limited supply of vaccinations to stop the spread of an epidemic.

The looping rate and sandpile density of planar graphs [PDF]

open access: yes, 2015
We give a simple formula for the looping rate of loop-erased random walk on a finite planar graph. The looping rate is closely related to the expected amount of sand in a recurrent sandpile on the graph.

Small grid embeddings of 3-polytopes [PDF]

open access: yes, 2009
We introduce an algorithm that embeds a given 3-connected planar graph as a convex 3-polytope with integer coordinates. The size of the coordinates is bounded by $O(2^{7.55n})=O(188^{n})$.

The Complexity of Simultaneous Geometric Graph Embedding [PDF]

open access: yes, 2015
Given a collection of planar graphs $G_1,\dots,G_k$ on the same set $V$ of $n$ vertices, the simultaneous geometric embedding (with mapping) problem, or simply $k$-SGE, is to find a set $P$ of $n$ points in the plane and a bijection $\phi: V \to P$ such ...
