$4$-total mean cordial labeling in subdivision graphs
Volume 52, Issue 2 , December 2020, Pages 1-11
Abstract
Let $G$ be a graph. Let $f:V\left(G\right)\rightarrow \left\{0,1,2,\ldots,k-1\right\}$ be a function where $k\in \mathbb{N}$ and $k>1$. For each edge $uv$, assign the label $f\left(uv\right)=\left\lceil \frac{f\left(u\right)+f\left(v\right)}{2}\right\rceil$. $f$ is called $k$-total mean cordial ... Read MoreLinear optimization constrained by fuzzy inequalities defined by Max-Min averaging operator
Volume 52, Issue 2 , December 2020, Pages 13-28
Abstract
In this paper, optimization of a linear objective function with fuzzy relational inequality constraints is investigated whereby the feasible region is formed as the intersection of two inequality fuzzy systems and \textquotedblleft Fuzzy Max-Min\textquotedblright \ averaging operator is considered as ...

Volume 52, Issue 2 , December 2020, Pages 29-40
Abstract
Generally, no one can reject the fact that crypto currency market is expanded rapidly during last few years as, nowadays, crypto currency market is attractive for both traders and business who are not willing to pay for FATF services for transferring money. With this in mind, crypto currency price prediction ... Read MoreImplementation of Combinational Logic Circuits Using Nearest-Neighbor One-Dimensional Four-State Cellular Automata
Volume 52, Issue 2 , December 2020, Pages 41-56
Abstract
Cellular automata are simple mathematical idealizations of natural systems. They consist of a lattice of discrete identical sites, each site taking on a finite set of, say, integer values. Over the years, scientists have been trying to investigate the computational capabilities of cellular automata by ... Read MoreOn the domination number of generalized Petersen graphs
Volume 52, Issue 2 , December 2020, Pages 57-65
Abstract
Let $n$ and $k$ be integers such that $3\leq 2k+ 1 \leq n$.The generalized Petersen graph $GP(n, k)=(V,E) $ is the graph with $V=\{u_1, u_2,\ldots, u_n\}\cup\{v_1, v_2,\ldots, v_n\}$ and $E=\{u_iu_{i+1}, u_iv_i, v_iv_{i+k}: 1 \leq i \leq n\}$, whereaddition is in modulo $n$. A subset $D\subseteq V$ is ... Read MoreOn Hardy's Apology Numbers
Volume 52, Issue 2 , December 2020, Pages 67-83
Abstract
Twelve well known `Recreational' numbers are generalized and classified in three generalized types Hardy, Dudeney, and Wells. A novel proof method to limit the search for the numbers is exemplified for each of the types. Combinatorial operators are defined to ease programming the search. Read MoreLP Problems on the max - “Fuzzy Or” inequalities systems
Volume 52, Issue 2 , December 2020, Pages 85-98
Abstract
In this paper, optimization of a linear objective function with fuzzy relational inequality constraints is investigated whereby the feasible region is formed as the intersection of two inequality fuzzy systems and “Fuzzy Or” operator is considered as fuzzy composition. It is shown that a ... Read MoreGeneralization of DP Curves and Surfaces
Volume 52, Issue 2 , December 2020, Pages 99-108
Abstract
In CAGD, the DP curves are known as a normalized totally positive curves that have the linear computational complexity. Because of their geometric properties, these curves will have the shape preserving properties, that is, the form of the curve will maintain the shape of the ... Read MoreOn the optimization of Hadoop MapReduce default job scheduling through dynamic job prioritization
Volume 52, Issue 2 , December 2020, Pages 109-126
Abstract
One of the most popular frameworks for big data processing is Apache Hadoop MapReduce. The default Hadoop scheduler uses queue system. However, it does not consider any specific priority for the jobs required for MapReduce programming model. In this paper, a new dynamic score is developed to improve ... Read MoreFuzzy Cumulative Distribution Function and its Properties
Volume 52, Issue 2 , December 2020, Pages 127-136
Abstract
The statistical methods based on cumulative distribution function is a start point for many parametric or nonparametric statistical inferences. However, there are many practical problems that require dealing with observations/parameters that represent inherently imprecise. However, Hesamian ... Read MoreTwo different inverse eigenvalue problems for nonsymmetric tridiagonal matrices
Volume 52, Issue 2 , December 2020, Pages 137-148
Abstract
Inverse eigenvalue problems (IEPs) of tridiagonal matrices are among the most popular IEPs, this is due to the widespread application of this matrix. In this paper, two different IEPs with different eigen information including eigenvalues and eigenvectors are presented on the nonsymmetric ...
