Consider the following cities (listed as nodes 1 to 10 in the graph below) to visited by a salesman. Using any Ant Colony Algorithm (ACO), find the shortest path if the salesman has to start from node 1. The distance in km is denoted on each edge on the graph below. Note that a path is considered valid when all nodes are visited, and the salesman is able to get back to its starting point. 70/ 60 30 30 10 10 70 (10) 50 60 50 40 20 80 70 70 3 20 90 70 5 60 Write down your ACO algorithm/pseudocode which should be designed specifically for this problem. Marks will be attributed for each part of the algorithm explained successfully. Ensure that all matrices (for pheromone and distance) and variables to be used in the algorithm are clearly named and explained.
