arXiv:2601.22211v2 Announce Type: replace Abstract: Reinforcement learning (RL) with combinatorial action spaces remains challenging because feasible action sets are exponentially large and governed by complex feasibility constraints, making direct policy parameterization impractical. Existing approaches embed task-specific value functions into constrained optimization programs or learn deterministic structured policies, sacrificing generality and policy expressiveness. We propose a solver-induced \emph{latent spherical flow policy} that brings the expressiveness of modern generative policies
The paper addresses a long-standing challenge in reinforcement learning, suggesting a breakthrough in handling complex combinatorial action spaces which are prevalent in real-world problems.
This research provides a more expressive and efficient way for AI systems to navigate and execute actions in environments with a vast number of choices, critical for advanced automation and autonomy.
The proposed 'latent spherical flow policy' could make reinforcement learning more practical for applications previously limited by the intractable complexity of action spaces, leading to more robust and generalized AI solutions.
