Intelligent agents is a foundational concept and research paradigm within artificial intelligence and computer science. It defines entities designed to perceive their environment and actuate within it to achieve specific objectives, typically aiming to maximize a performance measure over time. The field investigates the principles and methodologies for designing, implementing, and analyzing such entities, focusing on key characteristics such as perception, reasoning, decision-making under uncertainty, learning, and autonomous action. Its significance lies in providing a unifying framework for understanding, developing, and deploying systems capable of exhibiting intelligent, goal-directed behavior in complex environments.
