Multi-Agent Path Finding for Large Agents
Original language description
Multi-Agent Path Finding (MAPF) has been widely studied in the AI community. For example, Conflict-Based Search(CBS) is a state-of-the-art MAPF algorithm based on a two-level tree-search. However, previous MAPF algorithms assume that an agent occupies only a single location at any given time, e.g., a single cell in a grid. This limits their applicability in many real-world domains that have geometric agents in lieu of point agents. In this paper, we formalize and study MAPF for large agents that considers the shapesof agents. We present a generalized version of CBS, called Multi-Constraint CBS (MC-CBS), that adds multiple constraints (instead of one constraint) for an agent when it generates a high-level search node. Experimental results show thatall MC-CBS variants significantly outperform CBS. The best variant also outperforms EPEA* (a state-of-the-art A*-based MAPF solver) in all cases and MDD-SAT (a state-of-the-art reduction-based MAPF solver) in some cases.
