Travelling Salesman Problem Statement: Given n cities with known distances between each pair, find the shortest tour that passes through all the cities exactly once before returning to the starting city. On the following graph: Use Exhaustive Search to find the shortest path, starting from a, and returning back to a. Show all paths/tour that will be taken into consideration in this approach, compute costs for each tour involved, and find the most optimal path/tour from your computed costs. (Hint: Optimal path: minimum cost)
