Software agents are computer programs designed to perform specific tasks autonomously or semi-autonomously. They can analyze data, make decisions, and interact with users or other systems without constant human intervention. Common examples include chatbots, recommendation systems, and automated trading systems. These agents often use artificial intelligence techniques to learn from their environment and improve their performance over time. They can operate in various domains, such as e-commerce, customer service, and robotics, making them valuable tools for enhancing efficiency and user experience in many applications.
