How Much, Then Where: Credit-Conserving Action-to-Token Allocation for Multi-Turn Agent Reinforcement Learning

Lichao Ma, Yang Sun, Shuaitao Zhao +9

Credit assignment in multi-turn agent reinforcement learning operates at two levels: assigning trajectory-level credit to actions and distributing each action's credit across its t…

From Brewing to Resolution: Tracing the Internal Lifecycle of Code Reasoning in LLMs

Siyue Chen, Yifu Guo, Yuquan Lu +9

Standard accuracy metrics cannot explain why LLMs handle variable tracking but fail on semantically equivalent loops. We study an internal lifecycle of code reasoning in which mode…
