Graph Theory for the Middle School. [PDF]

open access: yes, 2006
After being introduced to graph theory and realizing how it can be utilized to solve real-world problems, the author decided to create modules of study on graph theory appropriate for middle school students. In this thesis, four modules were developed in

Total Semirelib Graph [PDF]

open access: yes, 2013
In this paper, the concept of Total semirelib graph of a planar graph is introduced. Authors present a characterization of those graphs whose total semirelib graphs are planar, outer planar, Eulerian, hamiltonian with crossing number ...

An algorithm to recognize a middle graph

open access: yesDiscrete Applied Mathematics, 1984
AbstractA graph F is called middle if there exists a graph G such that there is a one-to-one correspondence between the vertices of F and the vertices and edges of G such that two vertices of F are adjacent if and only if the corresponding elements (considered as subsets of the set of vertices) have a non-empty intersection.In this paper we present a ...

On Strong Split Middle Domination of a Graph [PDF]

open access: yes, 2016
The middle graph M(G) of graph G is obtained by inserting a vertex xi in the “middle” of each edge ei, 1 ? i ? |E(G)|, and adding the edge xixj for 1?i ? j ? |E(G)| if and only if ei and ej have a common vertex.

On k-rainbow domination in middle graphs [PDF]

open access: yesRAIRO - Operations Research, 2021
Let G be a finite simple graph with vertex set V(G) and edge set E(G). A function f : V(G) → P({1,2,…,k}) is a k-rainbow dominating function on G if for each vertex v∈V(G) for which f(v) = ∅, it holds that ⋃u∈N(v) f(u) = {1,2,…,k}. The weight of a k-rainbow dominating function is the value ∑v∈V(G)|f(v)|.

Feature Selection and Combination of Information in the Functional Brain Connectome for Discrimination of Mild Cognitive Impairment and Analyses of Altered Brain Patterns

open access: yesFrontiers in Aging Neuroscience, 2020
Mild cognitive impairment (MCI) is often considered a critical time window for predicting early conversion to Alzheimer’s disease (AD). Brain functional connectome data (i.e., functional connections, global and nodal graph metrics) based on resting-state
