WebTravelling salesman problem is the most notorious computational problem. We can use brute-force approach to evaluate every possible tour and select the best one. For n number of vertices in a graph, there are (n - 1)! number of possibilities. Instead of brute-force using dynamic programming approach, the solution can be obtained in lesser time ... WebJul 30, 2024 · Edit: This is the Traveling Salesman Problem (TSP), which is NP-Hard. I want to find a demonstration for this approximation algorithm: Greedy algorithm: Sort list L of all edges; Create empty list I; for e in L: 3.1 if I+e does not form a cycle, add e to I; return I; I used "+" to show the union between a list and a element
