RefCon: Iterative Refinement and Contrastive Memory Extraction for Context-Evolving Agent

Ubaidillah Ariq Prathama, Bo Liu, Yeo Boon Hong +3

Long-horizon agent interactions generate useful but noisy experience, and retraining models to absorb it is expensive. Context-evolving agents therefore need memory extraction meth…

Bayes-Sufficient Compression Is Not Enough: How Does Communication Help Multi-Agent Systems?

Yi Xie, Zhanke Zhou, Yi Fan +3

Multi-agent LLM systems pair a sender with broad context and an executor with a limited local view. We study when a short message improves the executor's next decision, when raw co…

TeamTR: Trust-Region Fine-Tuning for Multi-Agent LLM Coordination

Yi Xie, Siao Liu, Falong Fan +3

Multi-agent LLM systems have shown promise for complex reasoning, yet recent evaluations reveal they often underperform single-model baselines. We identify a structural failure mod…
