Edge Colouring of Neutrosophic Graphs and Its Application in Detection of Phishing Website

open access: yesDiscrete Dynamics in Nature and Society, 2022
Graph colouring enjoys many practical as well as theoretical uses. Graph colouring is still a very active subject of research. This article introduces a new concept of the chromatic number of the neutrosophic graph (NG).

A new approach to fuzzy group theory using (𝛼, 𝛽) -Pythagorean fuzzy sets [PDF]

open access: yesSongklanakarin Journal of Science and Technology (SJST), 2021
A Pythagorean fuzzy set (PFS) is a very efficient and powerful tool for handling uncertainty and vagueness. In this paper, we present the notion of (𝛼, 𝛽) -Pythagorean fuzzy set (PFS) as a generalisation of Pythagorean fuzzy set (PFS). We propose a new

The Reformulated F-Index of Vertex and Edge F-Join of Graphs

open access: yesJournal of Chemistry, 2022
The valency based topological indices (TIs) are defined by algebraic functions as the chemical graph theory tools in which the structural parameters are used as input and the output is related with the topology of chemical species.

An investigation of edge F-index on fuzzy graphs and application in molecular chemistry

open access: yesComplex & Intelligent Systems, 2022
The molecular descriptors are a useful tool in the spectral graph, molecular chemistry and several fields of chemistry and mathematics. The edge F-index is proposed for fuzzy graphs (FGs) here. Bounds of this index are calculated for FGs. The FG has been

Optimum Intervention in Transportation Networks Using Multimodal System under Fuzzy Stochastic Environment

open access: yesJournal of Advanced Transportation, 2022
Multimodal transport refers to the transportation of goods under a single contract but performed with at least two different modes of transport. This research designs a new method for solving the Transportation Problem (TP) by introducing multimodal ...

On the Reformulated Second Zagreb Index of Graph Operations

open access: yesJournal of Chemistry, 2021
Topological indices (TIs) are expressed by constant real numbers that reveal the structure of the graphs in QSAR/QSPR investigation. The reformulated second Zagreb index (RSZI) is such a novel TI having good correlations with various physical attributes,

On the Inverse Problem for Some Topological Indices

open access: yesJournal of Mathematics, 2021
The study of the inverse problem (IP) based on the topological indices (TIs) deals with the numerical relations to TIs. Mathematically, the IP can be expressed as follows: given a graph parameter/TI that assigns a non-negative integer value g to every ...
