The Travelling Salesman Problem (TSP) is the most known computer science optimization problem in a modern world. In simple words, it is a problem of finding optimal route between nodes in the graph. The total travel distance can be one of the optimization criterion. For more details on TSP please take a look here. 4. Java ModelThe travelling salesperson problem (TSP) is a classic optimization problem where the goal is to determine the shortest tour of a collection of n “cities” (i.e. nodes), starting and ending in the same city and visiting all of the other cities exactly once. In such a situation, a solution can be represented by a vector of n integers, each in ...This problem is called the Traveling salesman problem (TSP) because the question can be framed like this: Suppose a salesman needs to give sales pitches in four cities. He looks up the airfares between each city, and puts the costs in a graph. In what order should he travel to visit each city once then return home with the lowest cost?The problem. Image by the example. Now, we need to calculate lower bounds. For each city i, 1 ≤ i ≤ n, we will find the sum s_i of the distances from city i to the two nearest cities; and then we will compute the sum s of these n numbers. After, we will divide the results by 2, and, round up the result to the nearest integer.The TSP is a hard problem There is no known polynomial time algorithm. Cannot bound the running time as less than nk for any fixed integer k (say k = 15). If there were a polynomial time algorithm, there would be a polynomial time algorithm for every NP-complete problem. Question: what does one do with a hard problem? 9
