Traditional Deep Reinforcement Learning (DRL) models used in air traffic control suffer from a critical flaw known as "unimodal bias." This means they tend to learn a single, optimal strategy for resolving a conflict. While effective in simple scenarios, this rigidity leads to "decision deadlocks" when faced with complex, dynamic constraints. If their one preferred solution is blocked (e.g., by weather or another aircraft), they lack the flexibility to adapt, significantly increasing risk.
The proposed Diffusion-AC framework fundamentally changes this paradigm. Instead of learning one action, it models its policy as a reverse denoising process. This allows it to generate a rich, multimodal distribution of high-quality actions. For a single conflict, it can simultaneously propose several different, equally viable solutions (e.g., "turn right," "descend and hold speed," "decelerate and climb"). This creates an inherent library of safe maneuvers, making the system dramatically more robust and adaptable to real-world complexities.
To ensure the agent learns effectively, the system incorporates a Density-Progressive Safety Curriculum (DPSC). Training begins in a simple, sparse traffic environment, allowing the AI to master fundamental conflict resolution. As the agent's performance improves, the curriculum progressively increases the traffic density and complexity. This staged approach prevents the model from being overwhelmed early on and ensures it develops a robust, generalizable skillset capable of handling the most challenging, high-density scenarios.

Decision Flexibility
Instead of one rigid plan, the Diffusion-AC agent maintains a portfolio of safe maneuvers, dynamically selecting the best option when constraints change. This avoids the "decision deadlocks" plaguing unimodal models.

Case Study: The Non-Negotiable Core
An ablation study was performed to test the framework's components. When the Value Guidance mechanism (which steers the diffusion process towards high-reward actions) was removed, the system experienced a catastrophic failure. The success rate dropped from 94.1% to a mere 4.1%. This proves that while the diffusion model provides the expressiveness to find multiple solutions, the value guidance provides the intelligence to ensure those solutions are effective and safe.
