In this paper, we explore the connection between sensor networks and graph theory. Sensor networks represent distributed systems of interconnected devices that collect and transmit data, while graph theory provides a robust framework for modeling and ...

What do Eulerian and Hamiltonian cycles have to do with genome assembly? [PDF]
Many students are taught about genome assembly using the dichotomy between the complexity of finding Eulerian and Hamiltonian cycles (easy versus hard, respectively).

EULERIAN AND HAMILTONIAN PROPERTIES OF GALLAI AND ANTI-GALLAI TOTAL GRAPHS [PDF]
Let $G = (V, E)$ be a graph. The \textit{Gallai total graph} $\Gamma_T(G)$ of $G$ is the graph, where $V(\Gamma_T(G))=V \cup E$ and $uv \in E(\Gamma_T(G))$ if and only if \begin{itemize} \item[$(i)$] $u$ and $v$ are adjacent vertices in $G$, or \item[$(ii)$] $u$ is incident to $v$ or $v$ is incident to $u$ in $G$, or \item[$(iii)$] $u$ and $v$ are ...

Usage of Eulerian and Hamiltonian Graph in Pandemic Situation
The existence of Euler and Hamiltonian graph make it easier to solve a real-life problem. During the time of pandemic “Covid-19”, it is very essential for each one of us to be vaccinated. Vaccination is done in the hospitals by using Eulerian and Hamiltonian graphs not only to prevent people from infecting but also to increase the speed of vaccination.

On Eulerian and Hamiltonian Graphs and Line Graphs [PDF]
A graph G has a finite set V of points and a set X of lines each of which joins two distinct points (called its end-points), and no two lines join the same pair of points. A graph with one point and no line is trivial. A line is incident with each of its end-points. Two points are adjacent if they are joined by a line.

Hamiltonian problems in edge-colored complete graphs and eulerian cycles in edge-colored graphs : some complexity results [PDF]
Summary: In an edge-colored graph, we say that a path (cycle) is alternating if it has length at least 2 (3) and if any 2 adjacent edges of this path (cycle) have different colors. We give efficient algorithms for finding alternating factors with a minimum number of cycles and then, by using this result, we obtain polynomial algorithms for finding ...

Fuzzy Eulerian and Fuzzy Hamiltonian Graphs with Their Applications
In this article we discussed prominence of Fuzzy Eulerian and Fuzzy Hamiltonian graphs. Fuzzy logic is introduced to study the uncertainty of the event. In Fuzzy set theory we assign a membership value to each element of the set which ranges from 0 to 1. The earnest efforts of the researchers are perceivable in the relevant establishment of the subject

Eulerian subgraphs containing given vertices and hamiltonian line graphs
Let \(G\) be a graph and let \(D_1(G)\) be the set of vertices of degree 1 in \(G\). A graph is called an eulerian graph if it is connected and every vertex has even degree. An eulerian subgraph \(H\) of a graph \(G\) is called a dominating eulerian subgraph if \(G-V(H)\) is edgeless.
