Traveling Salesman Problem

Abstract. We study the Maximal Covering Salesman Problem with the Average Traveling Cost Constraints (MCSPATCC) where the objective is to find a subset of customers with their tour so that the number of covered demand points is maximized. This paper presents a mathematical model to select a profitable subset of demand points to be covered. We also propose an effective heuristic algorithm with three elimination methods to remove unprofitable demand points. The proposed algorithm is based on the genetic algorithm (GA) hybridized with different local search strategies to solve this problem. Parameters of the algorithm are analyzed for calibration by means of the Taguchi method. Extensive computational experiments on a set of standard problems …show more content…

Its associated problems were introduced by William Hamiltone and Thomas Kirkman in 18th century first time. Then, some mathematicians such as Karl Mengerfrom Harvard and Hustler Whitney from Princeton studied the general form of the traveling salesman problem [1], which is a reputable combinatorial optimization problem. Traveling salesman problem is consisting of a set of demand points and the distances each demand point. The objective of traveling salesman problem is to find the shortest possible route that visits each demand point (city) exactly once and returns to the origin city [1]. There are many practical applications for this type of problems such as finding an optimal tour for postmen and tourists [2], process planning for rotating items [3], flow shop scheduling [4], the robotic manipulator control [5], vehicle routing problem [6], computer network design [7], …show more content…

The problem consists of a central depot and a set of cities as demand points. The distance (time) between each two demand point and between the depot and each city is determined. A traveling salesman starts and ends the travel from/to the central depot. The salesman tries to cover some selected demand points among different demand points so that the average traveling cost, which is a function of distance, would not exceed a specified value and also the whole covered demands are maximized. In fact, the goal is to maximize the whole covered

Al Waysmoking was a 72 year-old retired factory worker who was a chain smoker. He is experiencing fatigue, shortness of breath, but continues to smoke. Upon exam his Nurse Practitioner notes that he has a prolonged expiratory phase, expiratory wheezes, and an increased anteroposterior chest diameter. His nail beds were cyanotic and he had moderate pitting edema. Pulmonary Function Testing (PFT) revealed that Al had a decreased VC and an increased RV and FRC.

State space is the city pairs (i,j) where the two friends are. 3.3 b) Option (iii) Is admissible since in the best situation, in which both friends head directly for each other, the friends will be going twice as far as the cost of the time of each step. 3.3 c) No there are not completely connected maps for which no solution exists, assuming that one friend can stay in the same city during any transition, since there maps are connected there is a guaranteed path from every city to every other city. 3.3 d) No, since an optimal solution would never involve doubling back to a city more than once since it does not contribute to the solution nor provide a more optimal

To compute rho, the program GSC threshold.m de nes two non-linear functions root2d and root2r as in Equation (15) and (16) of [1]. Each of these functions represents a system of non-linear equations in two variables. The program numerically solves these two by two systems of non-linear equations by using the inbuilt MatLab function f-solve. Since the probabilities, PNi are numerical solution computed by MatLab these values can be very very small numbers. To avoid these artifacts, the program replaces values of rho less than l_t by

In Figs. (\ref{fig:NC3Mont.eps}-\ref{fig:NC6Mont.eps}), the results of the Monte Carlo analysis is presented along with the result obtained for the central values of the parameter. It is observed that for the form factors $C_3^{N \Delta}(Q^2)$, $C_4^{N \Delta}(Q^2)$ and $C_6^{N \Delta}(Q^2)$, Monte Carlo analysis and the prediction for the central values agree at large values of $Q^2$, but deviate from each other for small values of

Why did the peoples of the Eastern Hemisphere develop long-distance trade more extensively than did those of the Western Hemisphere? One thing that I noticed that motivated the long-distance commerce of the Silk Roads, Sea Roads, and Sand Roads was the fact that the elites were desired luxury items from distant parts of the Eurasian network.

The Sisterhood of The Traveling Pants, written and published by Ann Brashares in 2001, is a book about four friends, spending the summer apart sharing pants that magically fit them all. The cinematic version was released on May 31, 2005, with a similar yet very different storyline compared to the young adult novel. For the most part, the cinematic version did a mediocre job at recreating the basic foundation of the book. For instance, the book starts out with Carmen, a heavier half Puerto Rican girl, thrift shopping with one of her best friends Lena and Lena’s sister Effie. Carmen buys the pants, but throws them in the back of her closet only to be found again at the beginning of summer.

The Island Hopping campaign implemented by the Allies in the Pacific Theater would not have been successful without the use of the Navajo Code Talkers. Code developed by the Navajo was indecipherable, and has been credited as the the only unbreakable code in military history. Prior to the involvement of the Navajo Indians the United States marines changed their code every twenty-four hours in an attempt to keep their enemies for decrypting the important messages. Hours were spent trying to code simple messages then send them to be decoded later; this was a great inconvenience to the Allies and extremely ineffective.

The knight’s tour In this paper, I will discuss the knight’s tour, a chess puzzle relatable to graph theory. I will talk about the history of the problem, how it is related to the Hamiltonian paths and circuits, and some techniques to finding the many different tours and proving their existence. The knight is, as you might know, the only chess piece that does not move in a straight line.
