Agents are autonomous entities that can perceive their environment, make decisions, and take actions to achieve their goals. They can be software-based, such as chatbots or autonomous vehicles, or physical entities like robots. Research in this area focuses on developing intelligent agents that can adapt to changing environments, collaborate with other agents, and solve complex problems efficiently. This includes studying areas such as machine learning, natural language processing, robotics, and multi-agent systems. Overall, the goal of agent research is to create intelligent entities that can interact with the world in a meaningful and autonomous way.
