A fuzzy graph theoretic approach to face shape recognition using cubic outerplanar structures [PDF]

open access: yesScientific Reports
The well-known topic of crisp graph planarity is contrasted with the more new and thoroughly studied field of planarity inside a fuzzy framework. In cubic fuzzy domain, cubic multisets with interval and fuzzy number to capture vagueness.

Exactly Hittable Interval Graphs [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2023
Given a set system $\mathcal{X} = \{\mathcal{U},\mathcal{S}\}$, where $\mathcal{U}$ is a set of elements and $\mathcal{S}$ is a set of subsets of $\mathcal{U}$, an exact hitting set $\mathcal{U}'$ is a subset of $\mathcal{U}$ such that each subset in ...

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).

Classes of graphs with restricted interval models [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 1999
We introduce q-proper interval graphs as interval graphs with interval models in which no interval is properly contained in more than q other intervals, and also provide a forbidden induced subgraph characterization of this class of graphs. We initiate a

Efficient enumeration of non-isomorphic interval graphs [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2021
Recently, Yamazaki et al. provided an algorithm that enumerates all non-isomorphic interval graphs on $n$ vertices with an $O(n^4)$ time delay. In this paper, we improve their algorithm and achieve $O(n^3 \log n)$ time delay.

Some Connectivity Parameters of Interval-Valued Intuitionistic Fuzzy Graphs with Applications

open access: yesAxioms, 2023
Connectivity in graphs is useful in describing different types of communication systems like neural networks, computer networks, etc. In the design of any network, it is essential to evaluate the connections based on their strengths.

Fast Diameter Computation within Split Graphs [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2021
When can we compute the diameter of a graph in quasi linear time? We address this question for the class of {\em split graphs}, that we observe to be the hardest instances for deciding whether the diameter is at most two.

On Edge Proper Interval-Valued Complex Fuzzy Graphs [PDF]

open access: yesE3S Web of Conferences, 2023
This article summarizes about edge proper interval-valued complex fuzzy graph. Here, degree of an edge, total degree of an edge, edge proper and edge totally proper intervalvalued complex fuzzy were introduced.
