Combining Propositional Logic Based Decision Diagrams with Decision Making in Urban Systems
This addresses safety and congestion challenges for urban multiagent systems, but appears incremental as it combines existing methods.
The paper tackled multiagent pathfinding under uncertainty and partial observability in urban systems by modeling it as a reinforcement learning problem, integrating propositional logic constraints to enable fast simulation.
Solving multiagent problems can be an uphill task due to uncertainty in the environment, partial observability, and scalability of the problem at hand. Especially in an urban setting, there are more challenges since we also need to maintain safety for all users while minimizing congestion of the agents as well as their travel times. To this end, we tackle the problem of multiagent pathfinding under uncertainty and partial observability where the agents are tasked to move from their starting points to ending points while also satisfying some constraints, e.g., low congestion, and model it as a multiagent reinforcement learning problem. We compile the domain constraints using propositional logic and integrate them with the RL algorithms to enable fast simulation for RL.
