MixedGraphinFuzzy,Neutrosophic, and Plithogenic Graphs [PDF]

open access: yesNeutrosophic Sets and Systems
Graph theory examines networks consisting of nodes (vertices) and the connections (edges) between them. Mixed graphs, which combine both undirected and directed edges, provide a versatile framework for representing relationships with symmetric and ...

A Graph Theoretic Perspective on CPM(Rel) [PDF]

open access: yesElectronic Proceedings in Theoretical Computer Science, 2015
Mixed states are of interest in quantum mechanics for modelling partial information. More recently categorical approaches to linguistics have also exploited the idea of mixed states to describe ambiguity and hyponym / hypernym relationships.

Mixed Moore Cayley Graphs [PDF]

open access: yesJournal of Interconnection Networks, 2017
The degree-diameter problem seeks to find the largest possible number of vertices in a graph having given diameter and given maximum degree. There has been much recent interest in the problem for mixed graphs, where we allow both undirected edges and directed arcs in the graph.

A Study on Semi-directed Graphs for Social Media Networks

open access: yesInternational Journal of Computational Intelligence Systems, 2021
In the literature of graph theory, networks are represented as directed graphs or undirected graphs and a mixed of both combinations. In today's era of computing, networks like brain and facebook that do not belong to any of the mentioned networks ...

Exploring Ways to Improve Elementary School Statistics Education Through Analysis of Middle School Social Studies Textbooks: Focusing on Statistical Graph Teaching

open access: yesJournal of Educational Research in Mathematics, 2020
In this study, in order to explore ways that statistical graphs teaching in elementary mathematics education can be improved, first, the types of statistical graphs that appear in middle school social textbooks were examined, and second, the ...

Research and Application of Hypernetwork Energy

open access: yesJisuanji kexue yu tansuo, 2021
Graph energy plays an important role in research of graph theory. Graph energy and many other similar variants have been applied in many other types of graphs, e.g., undirected graphs, oriented graphs, mixed graphs, and so on.
