The Travelling Salesman Problem With Integer Programming And.The traveling salesman problem is solved if there exists a shortest route that visits each destination once and permits the salesman to return home. (This route is called a Hamiltonian Cycle and will be explained in Chapter 2.) The traveling salesman problem can be divided into two types: the problems where there is a path between ...Yes, definitely a problem I was studying at school. We are studying bitonic tours for the traveling salesman problem. Anyway, say I have 5 vertices {0,1,2,3,4}. I know my first step is to sort these in order of increasing x-coordinates. From there, I am a bit confused on how this would be done with dynamic programming.
