## Travelling salesman problem example

Jun 28, 2020 · The traveling salesman problem (TSP) is a famous problem in computer science. The problem might be summarized as follows: imagine you are a salesperson who needs to visit some number of cities. Because you want to minimize costs spent on traveling (or maybe you’re just lazy like I am), you want to find out the most efficient route, one that will require the least amount of traveling. You are ... Naive Solution: 1) Consider city 1 as the starting and ending point. 2) Generate all (n-1)! Permutations of cities. 3) Calculate the cost of every permutation and keep track of the minimum cost permutation. 4) Return the permutation with minimum cost. Time Complexity: Θ (n!) Dynamic Programming: Let the given set of vertices be {1, 2, 3, 4,….n}.For example, branch A in the tree diagram has a sum of 10 + 2 + 11 + 13 = 36 10 + 2 + 11 + 13 = 36.
