Some new results on the number of fair dominating sets

Saeid Alikhani; Davood Bakhshesh; Nasrin Jafari; Maryam Safazadeh

Volume 54, Issue 2 , December 2022, Pages 1-12


  Let $G=(V, E)$ be a simple graph. A dominating set of $G$ is a subset $D\subseteq V$ such that every vertex not in $D$ is adjacent to at least one vertex in $D$. The cardinality of the smallest dominating set of $G$, denoted by $\gamma(G)$, is the domination number of $G$. For $k \geq 1$, a $k$-fair ...  Read More

Remarks on a rendering method for limit sets of Kleinian groups

alessandro rosa

Volume 54, Issue 2 , December 2022, Pages 13-19


  We revised our technique for generating graphical renderings of the limitsets of Kleinian groups. The algorithm, relying on numerical base conversion,has been improved to shorten computation times. This method easily applies toany family of Kleinian groups with an arbitrary number of generators.Following ...  Read More

Opinion Fraud Detection in Streaming Comments Utilising Node Similarity in the Review Network

Shahab Ghodsi; Ali Moieni

Volume 54, Issue 2 , December 2022, Pages 21-35


  One important criterion in decision-making when we want to purchase a product or a service is users’ reviews. When something is valuable, it’s fake and will be created as well. It is the same for users’ reviews. The purpose of these fake reviews is to deceive users, leading them to ...  Read More

Pair Difference Cordial Labeling of $m-$ copies of Path, Cycle, Star, and Ladder Graphs

R Ponraj; A Gayathri; Prof.Dr M.Sivakumar

Volume 54, Issue 2 , December 2022, Pages 37-47


  In this paper, we consider only finite, undirected, and simple graphs. The concept of cordial labeling was introduced by Cahit[4]. Different types of cordial-related labeling were studied in [1, 2, 3, 5, 16]. In a similar line, the notion of pair difference cordial labeling of a graph was introduced ...  Read More

An Efficient Gannet Optimization Algorithm for Feature Selection based on Sensitivity and Specificity

Najme mansouri; Amir Mohammad Sharafaddini

Volume 54, Issue 2 , December 2022, Pages 49-69


  The selection of features is a crucial step in the analysis of high-dimensional data in machine learning and data mining. Gannet Optimization Algorithm (GOA) is a recently proposed metaheuristic algorithm that has not yet been investigated in terms of its capacity to solve feature selection problems. ...  Read More

C. elegans Neural Network Analysis

Maliheh Ghomsheh; Ali Kamandi

Volume 54, Issue 2 , December 2022, Pages 71-91


  Artificial neural networks that have been so popular in recent years, are inspired from biological neural networks in the nature. The aim of this work is to study the properties of biological neural networks to find out what is actually happening in these networks. To do so, we study on Caenrohibditis ...  Read More

Volume 54, Issue 2 , December 2022, Pages 93-103


  In this article, we examine different algorithms in the field of cryptography. And we analyze them from different aspects. Also, we introduce a new solution and algorithm, based on increasing data security. Our proposed method can perform the task optimally and efficiently compared to similar algorithms. ...  Read More

Turbulent Supply Chain Control with Entropy Minimization Approach

Mojtaba Azizian; Mohammad Mehdi Sepehri

Volume 54, Issue 2 , December 2022, Pages 105-122


  Entropy is a measure of disorder in a system and is widely used in other scientific and engineering disciplines such as statistical mechanics and information theory. In a chaotic supply chain, the goal is to reduce chaotic behaviors and predict the future of the supply chain. In this case, relationships ...  Read More

An algorithm to Solve the Linear Programming Problem Constrained with the Harmonic–Fuzzy Relational Equalities

Amin Ghodousian; Babak Sepehri Rad; oveys qodousian

Volume 54, Issue 2 , December 2022, Pages 123-135


  In this paper, a linear programming problem is investigated in which the feasible region is formed as the intersection of fuzzy relational equalities and the harmonic mean operator is considered as fuzzy composition. Theoretical properties of the feasible region are derived. It is proved that the feasible ...  Read More

A Note on : The Effect of Lying in a Negotiation Game

Reza Habibi

Volume 54, Issue 2 , December 2022, Pages 137-142


  threaten system self-worth by preventing them from seeing themselves as a good system, and it can generally erode trust in society. Lying may be considered a game. This paper is concerned with the effect of lying in a system containing two agents using the game theory. From a repeated measurement model, ...  Read More
