“…After an ant finds a food source, on its way back to the nest, it lays down a pheromone trail, which increases the possibility of the fellow ants locating the food source. The fellow ants then follow the pheromone trace [4] and if they locate the food source, on their way back to the nest they lay down pheromone trails as well. If they did not find the food source, or the pheromone trail is far from optimal and it takes the ants too much time to get back to the nest, the pheromone trails evaporate, giving an opportunity to the other ants to locate the same food source via shorter path.…”
