This paper introduces a novel preference-conditioned Bellman operator based on Chebyshev scalarization to compute deterministic Pareto-optimal policies for Multi-Objective Markov Decision Processes, proving its convergence and effectiveness in capturing the entire Pareto frontier.
This paper introduces Path-Coupled Bellman Flows (PCBF), a continuous-time distributional reinforcement learning method that uses flow matching to model return distributions without heuristic projections. It addresses boundary mismatch and high-variance issues in previous flow-based approaches by coupling current and successor return flows through shared base noise.
