Why is the travelling salesman problem NP hard?
This means that TSP is classified as NP-hard because it has no “quick” solution and the complexity of calculating the best route will increase when you add more destinations to the problem. The problem can be solved by analyzing every round-trip route to determine the shortest one.
Which is a special type of transportation problem?
In this chapter, we focussed on a special type of transportation problem where the objective was to allocate n different facilities to n different tasks. Although an assignment problem can be formulated as a linear programming problem, it is solved by a special method known as Hungarian Method.
How do you solve the travelling salesman problem?
The key to this method is to always visit the nearest destination and then go back to the first city when all other cities are visited. To solve the TSP using this method, choose a random city and then look for the closest unvisited city and go there. Once you have visited all cities, you must return to the first city.
