Why do reinforcement-learned swarms coordinate in simulation and struggle after deployment? This episode explains SwarmACB's proposal to learn behavior selection instead of direct wheel control. We examine three questions: how behavioral modules change the learning problem, why attention and counterfactual credit assignment fit collective control, and what the reported physical evaluation establishes. The study evaluates controllers across five collective missions using 20 e-puck robots and 250 hardware runs, with the authors reporting stronger transfer from structured policies than from continuous-action control. We connect that result to AutoMoDe's modular design philosophy and earlier work on structured representations for swarm reinforcement learning. The discussion...
