Artificial Life
Artificial life is a broad field that involves imitating life in software, hardware, and biochemistry. Our work in this area focuses on computational modeling of behavior in simulated agents and teams of agents. In many cases, the behavior is modeled using neural networks and developed using neuroevolution. Specific topics include hierarchical and multimodal behaviors, social behavior, cooperation and competition, and communication.
