Cooperative systems refer to the study and development of systems that involve multiple entities, such as individuals, organizations, or machines, working together towards a common goal. This research area focuses on understanding the interactions and collaborations between these entities, as well as designing and implementing technologies to support cooperative activities. Cooperative systems can be applied in various domains, such as teamwork in organizations, collaboration in online social networks, coordination among autonomous vehicles, and distributed problem solving. Researchers in this field investigate topics such as communication protocols, group decision-making processes, task allocation mechanisms, and trust management in cooperative systems. Overall, cooperative systems research aims to improve the efficiency, effectiveness, and overall outcomes of collaborative endeavors by understanding and leveraging the interactions between multiple entities working towards a shared objective.
