<p align="center"><strong><em>Abstract</em></strong></p><p><em>Travelling Salesman Problem (TSP) is a quotidian stumbling block in the field of Computer Science and operation research designed to seek out the shortest pathway amid the given targets viz. cities where each target is considered only once. Many solutions to this setback like Ant Colony Optimization. Brute-Force approach, Genetic Algorithm, Fruit Fly Optimization etc. are available in literature. The main objective of these solutions is to minimize the time complexity and to search an optimized path that covers the entire region; however the urge of finding shortest path in minimum time still persists. This research work is an attempt to solve the above problem using clustering technique. Generally, for N cities the number of permutations conventionally considered are (N-1); for the proposed research work the permutations contemplated are reduced by the factor m. The results exhibit that the proposed method can effectively improve time complexity and search ability for achieving higher accuracy and optimal results. TSP discerns its application in X-Ray crystallography, the order-picking problem in warehouses, drilling of Printed Circuit Boards (PCB), mission planning problem etc. so an exigency for an optimum solution is requisite.</em></p><p><strong><em>Keywords: </em></strong><em>Brute-Force, lexicographic ordering, non-deterministic polynomial (NP) hard problem</em></p><p><strong>Cite this Article</strong></p><p>Hardik Dhingra, Gagan Deep Dhand, Rashmi Chawla, Shailende Gupta, Samarth Mittal.

<p align="center">The aim of this paper is to improve teaching efficiency with use of powerful educational software called 'MATLAB'. In this paper using the 'MATLAB' tool 'Makeshow' we attractively introduce normal probability distribution for the normally distributed random variables. Using these tool students can easily create interactive slideshows. Because of their rich library, available tools and demos matlab is easy to use for the students and so it provides option of self-study tool for them. This type of educational software allows the students to establish relationship between the problems solved in classroom and the reality that these problems refer to.<strong><em> </em></strong></p><p><strong>Cite this Article</strong></p><p>Bhavika M.

<p>In this paper, I design a NP-hard optimization problem and solve this problem by developing a nature-based multi-parent crossover in genetic algorithm (GA). Initially, taking a set of markets, a depot and some products for each of which a positive demand is specified. Purchaser can purchase each product from a subset of markets only a given quantity, less than or equal to the required one, can be purchased at a given unit price. Traveling purchaser forms a cycle starting at and ending to the depot and visiting a subset of markets at a minimum traveling cost. Here, I consider multiple vehicle to visit different markets say solid TPP (STPP). The activeness of my model is illustrated by numerical examples.</p><p><strong>Cite this Article</strong></p><p>Arindam Roy.

http://computers.stmjournals.com/index.php?journal=RRDMS&page=article&op=view&path%5B%5D=1833
<p>A distance compatible set labeling (dcsl) of a connected graph $G$ is an injective set assignment $f : V(G) \rightarrow 2^{X},$ $X$ being a non empty ground set, such that the corresponding induced function $f^{\oplus} :E(G) \rightarrow 2^{X}\setminus \{\phi\}$ given by $f^{\oplus}(uv)= f(u)\oplus f(v)$ satisfies $ |f^{\oplus}(uv)| = k_{(u,v)}^{f}d_{G}(u,v) $ for every pair of distinct vertices $u, v \in V(G),$ where $d_{G}(u,v)$ denotes the path distance between $u$ and $v$ and $k_{(u,v)}^{f}$ is a constant, not necessarily an integer, depending on the pair of vertices $u,v$ chosen. A dcsl $f$ of $G$ is $k$-uniform if all the constants of proportionality with respect to $f$ are equal to $k,$ and if $G$ admits such a dcsl then $G$ is called a $k$-uniform dcsl graph. Let $\mathcal{F}$ be a family of subsets of a set $X.$ A graph $G$ is defined to be a learning graph, if it is a ${\mathcal{F}}$-induced graph of some learning space ${\mathcal{F}}.$ A graph $G$ is called a topologically $k$-uniform dcsl graph, if $\{f(V(G)\}$, the collection of vertex labeling of $G$ is a topology. In this paper, we characterize topologically $1$-uniform dcsl learning graphs.</p><p><strong>Cite this Article</strong></p><p>Gency Joseph, L. Benedict Michael Raj, Germina K. Augusthy.

<p>A traffic intersection can be modelled by a graph by considering the streams as vertices and assigning an edge based on the mutually non-conflict streams. In this paper we propose a spectral approach to arrange the steams in order of their conflict and hence determine the most conflicted stream in a traffic intersection.<strong> </strong></p>Ankur Bharali2018-09-212018-09-216FD and DDA of N2 Function

<p>The object of the present paper is to establish the results of Double Dirichlet average (DDA) of N<sub>2</sub> Function, using Riemann-Liouville Fractional derivative (FD). This function is a modified form of Mittag-Leffler function [15]. The author drives the results between N2-function and fractional operators. The N<sub>2 </sub>Function can be measured as a Dirichlet average and connected with fractional calculus. In this paper the solution comes in compact form of double Dirichlet average of N<sub>2 </sub>Function.</p>Mohd.

http://computers.stmjournals.com/index.php?journal=RRDMS&page=article&op=view&path%5B%5D=1468
This paper uses a complex network approach to study the structure and robustness of Airport Network of India (ANI). The ANI displays small-world (SW) network properties with an average path length of 2.262 and a clustering coefficient of 0.605, and it also exhibits disassortative mixing on degree of nodes, that means the high-degree nodes in the network tend to have connections with low-degree nodes. Being a disassortative network, ANI doesn’t percolate more easily and less robust to node removal. A study of the robustness of ANI is also carried out for targeted node removal.Ankur BharaliDimpee Baruah2018-09-012018-09-016Vertex Odd Divisor Cordial Labeling of Ring Sum of Different Graphs With star Graph

<p>The curling number of a graph G is dened as the number of times an element in the degree sequence of G appears the maximum number of times. Graph colouring is an assignment of colours, labels or weights to the vertices or edges of a graph. A colouring C of colours c1, c2,..., cl is said to be a minimum parameter colouring if C consists of minimum number of colours with smallest subscripts. In this paper, we study the chromatic colouring version of curling number of certain derived graphs, with respect to their minimum parameter colourings.</p>Susanth ChandoorSudev NaduvathSunny Joseph Kalayathankal2018-05-282018-05-286Fibonacci Cordial Labeling of Some Graphs

In this paper, the author investigated the existence of Fibonacci Cordial Labeling of some Graphs.<strong></strong></em></p>amit himmatbhai rokad2018-04-092018-04-096
