Direct Reasoning Optimization: Token-Level Reasoning Reflectivity Meets Rubric Gates for Unverifiable Tasks

Yifei Xu, Tusher Chakraborty, Srinagesh Sharma +6

Reinforcement learning (RL) training of large language models (LLMs) on unverifiable tasks is challenging even when a reasonable-quality reference answer is available. We propose a…

AnyPro: Preference-Preserving Anycast Optimization based on Strategic AS-Path Prepending

Minyuan Zhou, Yuning Chen, Jiaqi Zheng +11

Operating large-scale anycast networks is challenging because client-to-site mappings often misalign with operator's expectation due to opaque inter-domain routing. We present AnyP…
