A variant of van Hoeij's algorithm to compute hypergeometric term solutions of holonomic recurrence equations
Articles in Press, Accepted Manuscript, Available Online from 13 January 2022
Abstract
Linear and homogeneous recurrence equations having polynomial coefficients are said to be holonomic. These equations are useful for proving and discovering combinatorial and hypergeometric identities. Given a field $\mathbb{K}$ of characteristic zero, $a_n$ is a hypergeometric term with respect to $\mathbb{K}$, ... Read MoreOverlapping Clusters in Cluster Convolutional Networks
Articles in Press, Accepted Manuscript, Available Online from 13 January 2022
Abstract
A popular research topic in Graph Convolutional Networks (GCNs) is to speedup the training time of the network. The main bottleneck in training GCN is the exponentially growing of computations. In Cluster-GCN based on this fact that each node and its neighbors are usually grouped ... Read MorePair difference cordial labeling of planar grid and mongolian tent
Articles in Press, Accepted Manuscript, Available Online from 13 January 2022
Abstract
\noindent Let $G = (V, E)$ be a $(p,q)$ graph.\\Define \begin{equation*}\rho =\begin{cases}\frac{p}{2} ,& \text{if $p$ is even}\\\frac{p-1}{2} ,& \text{if $p$ is odd}\\\end{cases}\end{equation*}\\ and $L = \{\pm1 ,\pm2, \pm3 , \cdots ,\pm\rho\}$ called the set of labels.\\\noindent ...

Articles in Press, Accepted Manuscript, Available Online from 14 January 2022
Abstract
In this paper, a type of fuzzy system is firstly investigated whereby the feasible region is defined by the fuzzy relational equalities and the geometric mean as fuzzy composition. Some related basic and theoretical properties are derived and the feasible region is completely determined. Moreover, a ... Read MoreOn the J-Tightness of Graphs
Articles in Press, Accepted Manuscript, Available Online from 14 January 2022
Abstract
We introduce a new invariant vulnerability parameter named “J-Tightness” or “J(G)” for graphs. As a stability measure, its properties along with comparisons to other parameters of a graph are proposed. We show how it is calculated for complete graphs and cycles. We show that J-Tightness ... Read MoreA fast algorithm for the linear programming problem constrained with the Weighted power mean -- Fuzzy Relational Equalities (WPM-FRE)
Articles in Press, Accepted Manuscript, Available Online from 14 January 2022
Abstract
In this paper, a linear programming problem is investigated in which the feasible region is formed as a special type of fuzzy relational equalities (FRE). In this type of FRE, fuzzy composition is considered as the weighted power mean operator (WPM). Some theoretical properties of the feasible region ... Read MoreFuzzy Cumulative Distribution Function \and its Properties
Articles in Press, Accepted Manuscript, Available Online from 14 January 2022
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 MoreAn algorithm to Solve the Linear Programming Problem Constrained with the Harmonic–Fuzzy Relational Equalities
Articles in Press, Accepted Manuscript, Available Online from 15 January 2022
Abstract
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 MorePlane Bounded-Degree Spanners Among the Obstacles for the Points in Convex Position
Articles in Press, Accepted Manuscript, Available Online from 15 January 2022
Abstract
Let $S$ be a set of points in the plane that are in convex position. Let~$\cal O$ be a set of simple polygonal obstacles whose vertices are in $S$. The visibility graph $Vis(S,{\cal O})$ is the graph which is obtained from the complete graph of $S$ by removing all edges intersecting some obstacle ...

Articles in Press, Accepted Manuscript, Available Online from 15 January 2022
Abstract
Confirming the integrity of transmitted sensitive digital content is a significant issue due to the evolution in communication technologies and the accessibility of image processing tools. Watermarking has been a successful method of authentication and integrity verification recently. However, several ... Read MoreOn the resolution of LP-FRE defined by the convex combination operator
Articles in Press, Accepted Manuscript, Available Online from 15 January 2022
Abstract
In this paper, a linear programming problem is investigated in which the feasible region is formed as a special type of fuzzy relational equalities (FRE). In this type of FRE, fuzzy composition is considered as the convex combination operator. It is proved that the feasible region of the problem can ... Read MorePriority-Oriented Task Scheduling based on Harris Hawks Optimizer for Cloud Computing
Articles in Press, Accepted Manuscript, Available Online from 15 January 2022
Abstract
Cloud computing is a high-performance computing environment that can remotely provide services to customers using a pay-per-use model. The principal challenge in cloud computing is task scheduling, in which tasks must be effectively allocated to resources. The mapping of cloud resources to customer ...

Articles in Press, Accepted Manuscript, Available Online from 16 January 2022
Abstract
\noindent Selecting suitable journals for publishing manuscripts for publication is one of the most essential processes before publishing any manuscript. Finding the relevant journal is a key factor which proves one's work valuable to the entire society. The final output and the performance of one's ...

Articles in Press, Accepted Manuscript, Available Online from 16 January 2022
Abstract
An edge coloring of a digraph $D$ is called a $P_3$-rainbow edge coloring if the edges of any directed path of $D$ with length 2 are colored with different colors. It is proved that for a $P_3$-rainbow edge coloring of a digraph $D$, at least $\left\lceil{log_2{\chi(D)}} ... Read MoreNegative Cost Girth Problem using Map-Reduce Framework
Articles in Press, Accepted Manuscript, Available Online from 16 January 2022
Abstract
On a graph with a negative cost cycle, the shortest path is undefined, but the number of edges of the shortest negative cost cycle could be computed. It is called Negative Cost Girth (NCG). The NCG problem is applied in many optimization issues such as scheduling and model verification. The existing ...
