Swarm Intelligence refers to the collective behavior of decentralized, self-organized systems, often observed in nature. It is commonly seen in groups of animals, such as ants, bees, and birds, where individuals follow simple rules and interact locally, leading to complex group behaviors. This phenomenon helps in tasks like foraging, navigation, and decision-making. In computer science and artificial intelligence, Swarm Intelligence is used to develop algorithms inspired by these natural systems. Techniques like Particle Swarm Optimization and Ant Colony Optimization mimic the behaviors of swarming animals to solve complex problems in areas such as optimization, robotics, and network design.
