An intelligent agent is a computer program or system that is designed to act autonomously and make decisions based on its environment and goals. Unlike traditional programs, which follow a predetermined set of instructions, intelligent agents have the ability to learn, adapt, and make decisions on their own. They use various techniques such as machine learning, natural language processing, and data analysis to gather information, reason, and take actions to achieve their objectives. Intelligent agents are used in a wide range of applications, from virtual personal assistants to self-driving cars, and are constantly evolving to become more efficient and effective in their tasks.
