(a) Representation of probability matrix. Each box stores the probability of traversing the arch . (b) Representation of the pheromone matrix, each box represents the amount of pheromone deposited by an ant when traversing the arch . (c) Representation of the route matrix, the column on the left represents the departure node at position and the right column represents the destination node at position .
