travelling salesman nodes

The generalized travelling salesman problem, also known as the "travelling politician problem", deals with "states" that have (one or more) "cities", and the salesman must visit exactly one city from each state.

The Travelling Salesman Problem (TSP) remains a complex enigma of business logistics, yet, the advent of sophisticated algorithms and innovative solutions are paving avenues to optimize routing, reduce travel costs further, and enhance customer interactions.

You can add a dummy node, which connects to start and end node with edges with weight 0. Since the TSP must contain the dummy node, the final result must contain the sequence start - dummy node - end (there is no other way to reach the dummy node).

The traveling salesman problem (TSP) is a widely studied combinatorial optimization problem, which, given a set of cities and a cost to travel from one city to another, seeks to identify the tour that will allow a salesman to visit each city only once, starting and ending in the same city, at the minimum cost. 1.

Considered the gold standard of solving the Travelling Salesman Problem, this algorithm utilizes insights from an easily solvable problem in graph theory (constructing a minimal spanning tree from a given graph) and manipulates it to arrive at (on average) comparatively shorter paths.

Travelling Salesman. As with other optimisation problems, we can make a decision problem version of the Travelling Salesman problem. The problem TSP consists of the set of triples. (V, c : V × V → IN, t) such that there is a tour of the set of vertices V , which under the cost matrix c, has cost t or less. 3.

6.4.5 Node Covering: The Traveling Salesman Problem. When deliveries, collections, or visits must be made to (or from) a number of specific (and, often, widely separated) points, the routing problem that must be solved becomes a node-covering one.

This is an example of a drawing solution of the traveling salesman problem. The function used to produce the solution is christofides , where given a set of nodes, it calculates the route of the nodes that the traveler has to follow in order to minimize the total cost.

If two nodes are not connected, add an edge with weight according to the shortest path between the nodes. Solve TSP, translate all added edges into their resp. paths. $\endgroup$ – Raphael
