Ant colony

Ant colony algorithm has three steps: pheromone initialization, building tour, updating pheromone.For the ant colony algorithm, path selection influence a little by the pheromone initialization. In order to get a better result, the pheromone value is always initialized slightly higher than the one released in each iteration.We have taken the initial value of pheromone as τij(0)= m/Cmin where , τij(t) is the residual pheromone on the path between node i and node j at moment t. m is the number of ants.Cmin is the minimum of product of distance and traffic density between the two junctions. In the process of planning path,the kth(k=1,2,...,m) ant chooses next junction based on probability S = [τij(t)]. [ij]…

Hi, Aaron here from the Leiningen plantation in southern Brazil. We are witnessing, first hand, the world’s largest army attempt to take on 400+ men armed with farm supplies and tools, ANTS! Every few years, an ant colony will expand outside its normal exploring territory and move all the way across South America. This colony arises other colonies along the way and builds their army of mass destruction. This swarm can grow up to 2 miles wide, and 10 miles long. That’s 20 square miles!! This…

Hypothesis 1.) Ants prefer food sources of a higher quality rather than of a lower quality. 2.) Ants are sensitive to foraging gains and predation risks. Predictions 1.) Ants will prefer to forage for sugar water that is highly concentrated rather than water that is less concentrated. 2.) Ants will prefer to forage close to their home net site rather than farther away from their home nest site. 3.) Ants will balance the trade-off between the risk of predation and food quality. Ants will take…

After reading the essays “The Myth of the Ant Queen”, “Project Classroom Makeover”, and “The Naked Citadel” by Steven Johnson, Cathy Davidson, and Susan Faludi, readers may have spotted that collective knowledge, different systems of organization, and the three terms identity, conformity and group mentality, are mentioned in their respective essays. Interestingly enough, these three completely different essays still have ideas that can work together to address a point: collective knowledge can…

In Dr Deborah Gordon tech talk, “How Ant Colonies Get Things Done” she presents her findings from studying a collection of ant colonies in New Mexico for the past 25 years. More specifically, she focus on the Red Carpenter ant species. While colonies of ants may look at first glance like simply a bunch of ants running around aimlessly, a closer and more careful look shows substantial social organization. A colony can solve problems unthinkable for individual ants, such as finding the shortest…

Society is a monarchy, with different levels of “power”. With the Queen’s Society, the ants were assigned different tasks. Near the beginning of the movie, you can see worker ants digging a tunnel. These ants were assigned the job a “worker ant”. The “worker ant” is in my opinion the lowest level of power in the society. There were also soldier ants shown throughout the movie. On a higher level, there is The General and his accomplices. This is the most successful society because ants…

ANT COLONY OTIMIZATION basics and algorithm 3.1. ACO algorithm introduction and basics The concept of ACO has been inspired by observation of real ants while wondering for food source. An ant while in search of food source lays a certain amount of pheromone trail along the path traversed. The laying of pheromone serves dual purpose to the ant. Firstly, it marks the path for other randomly moving aunts and secondly, it helps the aunt to return to its original source. Now, whenever a redundantly…

ANTZ Movie The movie Antz showcased several of the things that we learned so far in the civics course. The movie revolves around the fight between different ideologies of the types of government that should be in place. It also shows how being an active citizen and having social trade-off can help work for the common good of the community. It also shows that how our actions can greatly affect all the communities that we are a part of. There are many beliefs of the types of government that the…

Most ant species are social insects, living in large cooperative groups called colonies. Two or more generations may overlap in a colony. These ant colonies are divided into three castes — males, workers and queens — and each caste perform certain tasks. Queen ants and males are part of the reproductive castes. They are the most important members of a colony because they ensure the survival of their species. Queen ants, regardless of species, often are larger than other members of their…

social integration and progress. A city that holds close accord is the one whose members fulfill their roles adequately. Johnson, in his work “The Myth of the Ant Queen,” describes how ant colonies live in self-organized systems, and how this could apply to the human society. The word “Queen” associated with ant colonies means a leader in the human race, but it has an entirely…
