Cross-Agent Learning Signals Enable Coordinated Role-Decomposed LLM Training

The paper introduces DAC (Divide and Cooperate), a role‑decomposed training framework that separates evidence acquisition (searcher) and response generation (generator) in agentic search systems. DAC uses task‑specific external verification signals to provide cross‑verification rewards, allowing the generator to abstain when evidence is insufficient and to assign credit appropriately to each role. Experiments on seven QA benchmarks and two model backbones show that DAC consistently outperforms single‑agent and multi‑agent baselines, with gains attributed to coordinated improvements in both search and generation.

Constraint Tree Exploration for Learning from Language Feedback

The paper introduces TRACE, an algorithm that learns from natural‑language feedback by treating user intent as latent constraints and exploring feasible action regions organized in a tree. TRACE tests candidate constraints by generating compliant actions and only commits to a refinement when repeated feedback does not contradict it, offering two modes: falsification and identification. The authors provide theoretical coverage guarantees and demonstrate that TRACE‑Identification outperforms prompting baselines on six language‑feedback tasks, achieving higher success rates and robustness to identity corruption.

FreeEvolve: Learning to Evolve Beyond Fixed Loops

FREEEVOLVE automates the optimization loop used by agent evolvers, allowing the system to decide what to test, how much evidence to gather, which candidates to pursue, and when to stop, all within specified resource limits. By treating these decisions as an editable evolution skill and improving them through meta‑evolution, the method learns a capability that replaces hand‑crafted search loops. Experiments on several benchmarks show that FREEEVOLVE improves primary metrics by an average of 13.6 points and that meta‑evolved skills add further gains, indicating transferability across environments.
