Abstract: In this article, we present a simple performance bound for the greedy scheme in string optimization problems. Our approach generalizes the family of greedy curvature bounds established by ...

We propose TraceRL, a trajectory-aware reinforcement learning method for diffusion language models, which demonstrates the best performance among RL approaches for DLMs. We also introduce a ...

All results from 3 seeds × 18 test instances = 54 evaluation points. BO static outperforms PPO on small instances, but PPO overtakes at 500-variable scale. learned-control-layers/ ├── src/ │ ├── ...

Abstract: This study addresses a variant of the Vehicle Routing Problem (VRP) with customer priorities. In the variant, we assume the hard priority constraint where customers should be served in a ...
