Co-Evolution in Agentic Systems: Toward Self-Directed Evolution Beyond Human Design

Qing Zong, Jiayu Liu, Junhao Shen +9

Agentic systems are increasingly expected to improve after deployment, yet single-entity self-evolution is often bounded by a static learning context, such as fixed tasks and feedb…

Teaching LLMs to Self-Evolve: Cultivating Core Meta-Skills with Reinforcement Learning

Shujin Wu, Cheng Qian, Xiusi Chen +1

Test-time scaling through iterative self-evolution with environment feedback, as demonstrated by AlphaEvolve, shows remarkable performance gains. We hypothesize that the success of…

PEARL: Self-Evolving Assistant for Time Management with Reinforcement Learning

Bingxuan Li, Jeonghwan Kim, Cheng Qian +4

Overlapping calendar invitations force busy professionals to repeatedly decide which meetings to attend, reschedule, or decline. We refer to this preference-driven decision process…

PlanBench-XL: Evaluating Long-Horizon Planning of LLM Tool-Use Agents in Large-Scale Tool Ecosystems

Jiayu Liu, Qihan Lin, Cheng Qian +8

LLM agents increasingly operate in large tool ecosystems, where real-world tasks require discovering relevant tools, inferring implicit sub-goals, and adapting to dynamic environme…

BioInsight: Multi-Agent Orchestration for Interactive Biomedical Knowledge Discovery

Jieyi Wang, Bingxuan Li, Nanyi Jiang +9

Biomedical deep-research systems increasingly retrieve and synthesize scientific evidence, but their outputs typically collapse heterogeneous evidence into static text, making prov…
