##### $4$-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 ...

##### Linear 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 ...

##### Crypto- Currency Price Prediction with Decision Tree Based Regressions Approach

*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 ...

##### Implementation 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 ...

##### On 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 ...

##### On 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.

##### LP 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 ...

##### Generalization 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 ...

##### On 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 ...

##### Fuzzy 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 ...

##### Two 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 ...
