This document discusses swarm intelligence, which refers to the collective behavior of decentralized and self-organized systems. It provides examples of swarm intelligence in ant colonies, where colonies are able to complete complex tasks through simple local interactions between individuals. The document also describes how positive feedback loops allow for the emergence of intelligent group behavior without centralized control, as seen in ants choosing the shortest path to food through pheromone signaling. Finally, it discusses potential applications of swarm intelligence concepts in areas like robotics, scheduling, and telecommunications.
