Analysis
This paper addresses the challenge of discovering coordinated behaviors in multi-agent systems, a crucial area for improving exploration and planning. The exponential growth of the joint state space makes designing coordinated options difficult. The paper's novelty lies in its joint-state abstraction and the use of a neural graph Laplacian estimator to capture synchronization patterns, leading to stronger coordination compared to existing methods. The focus on 'spreadness' and the 'Fermat' state provides a novel perspective on measuring and promoting coordination.
