The paper compares classical motion planners with learning-based methods for real-time navigation in environments with dynamic hazards, using a unified benchmark that includes identical settings and metrics. In deterministic scenarios, classical planners achieve near-perfect success and high-quality paths, though they can incur significant planning time. When obstacle dynamics are stochastic, classical planners become highly budget-sensitive, whereas PPO-trained policies consistently deliver better latency, success rates, and path quality.

The paper presents a training-free diffusion-based motion planner that replaces learned global trajectory scores with analytical local scores derived from obstacle, smoothness, velocity, and inter-agent feasibility terms. By reconstructing trajectory scores through local interactions between neighboring waypoints and nearby constraints, the method decomposes the denoising process while preserving the optimization structure of classical trajectory methods. Experiments demonstrate that this approach generates smooth, feasible trajectories for large multi-agent tasks in complex environments quickly, outperforming learning-based and optimization baselines without requiring training data.
