Evolutionary adaptive behavior in noisy multi-agent system

In this paper, we discuss a relationship between perceptual noise and fitness of agents in a multi-agent system. In multi-agent system, agents perceive environmental information and act based on this information. Therefore, in case that the perceptual information contains some noise, a cooperative behavior of agents is more challenging and the resulting fitness of the agents is inferior. In order to develop a behavior of the agents that is robust to the perception noise, we evolved the behavior of the agents in noisy environment. As a result, the evolved behavior, obtained in a noisy environment is superior (in terms of robustness) than that evolved in noiseless environment.
