Swarm intelligence is a concept that describes how simple agents, like insects or robots, can work together to solve complex problems. This behavior is often observed in nature, such as in the way ants find food or birds migrate in flocks. Each individual follows simple rules, and their interactions lead to intelligent group behavior without a central control. Researchers study swarm intelligence to develop algorithms for various applications, including optimization and robotics. By mimicking the collective behavior of swarms, scientists can create systems that efficiently tackle tasks like data analysis or traffic management, demonstrating the power of collaboration in problem-solving.
