Energy and Spectrum Analysis of Interval Valued Neutrosophic Graph using MATLAB [PDF]

open access: yesNeutrosophic Sets and Systems, 2019
In recent time graphical analytics of uncertainty and indeterminacy has become major concern for data analytics researchers. In this direction, the mathematical algebra of neutrosophic graph is extended to interval-valued neutrosophic graph.

An Extension of Fuzzy Competition Graph and Its Uses in Manufacturing Industries

open access: yesMathematics, 2020
Competition graph is a graph which constitutes from a directed graph (digraph) with an edge between two vertices if they have some common preys in the digraph.

The power of interval models for computing graph centralities [PDF]

open access: yesRevista Română de Informatică și Automatică, 2022
Food webs, some scheduling problems and DNA molecules all have in common a “linear structure” which can be captured through the idealized model of interval graphs (intersection graphs of intervals on a line).

Algorithms for optimal min hop and foremost paths in interval temporal graphs

open access: yesApplied Network Science, 2022
Path problems are fundamental to the study of graphs. Temporal graphs are graphs in which the edges connecting the vertices change with time. Min hop paths problem in a temporal graph is the problem of finding time respecting paths from source vertex to ...

The Phylogeny Graphs of Doubly Partial Orders

open access: yesDiscussiones Mathematicae Graph Theory, 2013
The competition graph of a doubly partial order is known to be an interval graph. The CCE graph and the niche graph of a doubly partial order are also known to be interval graphs if the graphs do not contain a cycle of length four and three as an induced

A Characterization of 2-Tree Probe Interval Graphs

open access: yesDiscussiones Mathematicae Graph Theory, 2014
A graph is a probe interval graph if its vertices correspond to some set of intervals of the real line and can be partitioned into sets P and N so that vertices are adjacent if and only if their corresponding intervals intersect and at least one belongs ...

Interval graphs and seatching

open access: yesDiscrete Mathematics, 1985
The interval thickness of a graph G is the minimum clique number of all the interval supergraphs of G. The clique number of a graph is the number of nodes of its biggest complete subgraph. On the other hand, the node- search number is the least number of searchers (pebbles) required to clear the ''contaminated'' edges of a graph. A contaminated edge is

The list Distinguishing Number Equals the Distinguishing Number for Interval Graphs

open access: yesDiscussiones Mathematicae Graph Theory, 2017
A distinguishing coloring of a graph G is a coloring of the vertices so that every nontrivial automorphism of G maps some vertex to a vertex with a different color. The distinguishing number of G is the minimum k such that G has a distinguishing coloring

Some Root Level Modifications in Interval Valued Fuzzy Graphs and Their Generalizations Including Neutrosophic Graphs

open access: yesMathematics, 2019
Fuzzy graphs (FGs) and their generalizations have played an essential role in dealing with real-life problems involving uncertainties. The goal of this article is to show some serious flaws in the existing definitions of several root-level generalized FG
