The multi-agent model is a model in which agents with limited ability
cooperate each other to accomplish a goal. In this paper, we introduce
a multi-agent model in which agents are created to imitate real ants.
There are two different type of agents, each type of which has a part
icular task. We designed agents to communicate each other by using phe
romone considering noise. On this model, we observed cooperative behav
ior of agents and evaluated conditions to make an order of behavior in
the model. (C) 1997 Elsevier Science Ltd.
