The Takeaway

By replacing centralized, time-expanded models with spatial detours (GCP) and local authorization queues (DLC), it avoids the exponential complexity of traditional MAPF solvers. This enables real-time coordination for massive robot fleets in dense environments like automated warehouses.

From the abstract

Multi-Agent Path Finding (MAPF) requires collision-free trajectories for multiple agents on a shared graph, often with the objective of minimizing the sum-of-costs (SOC). Many optimal and bounded-suboptimal solvers rely on time-expanded models and centralized conflict resolution, which limits scalability in large or dense instances. We propose a hybrid prioritized framework that separates geometric planning from execution-time conflict resolution. In the first stage, Geometric Conflict Preemptio
