Swarm intelligence mathematically equivalent to single-agent RL

Researchers have established a mathematical equivalence between collective decision-making through imitation and single-agent reinforcement learning (RL) in a multi-armed bandit setting. The study demonstrates that even when individuals in a population merely copy their peers without learning, the group's collective behavior updates according to a macroscopic RL algorithm termed Maynard-Cross Learning (MCL). In this framework, each individual acts as a parallel environment rollout, with their influence on the group mirroring an RL learning rate proportional to the inverse of the swarm size. AI

IMPACT Provides a theoretical framework for understanding how collective intelligence can emerge from simple imitation, potentially informing the design of decentralized AI systems.
