Existing LLM routers choose one model per query, so they only fit single-agent setups. They ignore how agents should cooperate and which roles they should play. The authors formalize this broader task as Multi-Agent… 2. **[G-Safeguard: A Topology-Guided Security Lens and Treatment on LLM-based Multi-agent Systems](https://md.research.elamur.ai/free/en/papers/wang-2025-g-safeguard-topology-guided-security/)** *(2025 · 30 citations)* Multi-agent systems built on LLMs inherit the weaknesses of single agents. They also gain a new one: a compromised agent can spread misinformation or malicious instructions through inter-agent communication until much of the system is corrupted. G-Safeguard defends against this by treating the system's communication… 3. **[Scaling Behaviors of LLM Reinforcement Learning Post-Training: An Empirical Study in Mathematical Reasoning](https://md.research.elamur.ai/free/en/papers/tan-2026-scaling-behaviors-llm-reinforcement-learning/)** *(2026 · 6 citations)* Scaling laws are well established for LLM pre-training, but little is known about how they behave when reinforcement learning is applied after pre-training. ## All works 5 works of theirs in our library, the most cited first; 3 with a page here, the others link their original until we summarise them. 1. **[MasRouter: Learning to Route LLMs for Multi-Agent Systems](https://md.research.elamur.ai/free/en/papers/yue-2025-masrouter-learning-route-llms-multi/) [Annual Meeting of the Association for Computational Linguistics (ACL)](https://md.research.elamur.ai/free/en/venues/acl/)**Yanwei Yue, Guibin Zhang, Boyang Liu, et al.*2025 · 35 citations* 2. **[G-Safeguard: A Topology-Guided Security Lens and Treatment on LLM-based Multi-agent Systems](https://md.research.elamur.ai/free/en/papers/wang-2025-g-safeguard-topology-guided-security/) [Annual Meeting of the Association for Computational Linguistics (ACL)](https://md.research.elamur.ai/free/en/venues/acl/)**Shilong Wang, Guibin Zhang, Miao Yu, et al.*2025 · 30 citations* 3. **[Scaling Behaviors of LLM Reinforcement Learning Post-Training: An Empirical Study in Mathematical Reasoning](https://md.research.elamur.ai/free/en/papers/tan-2026-scaling-behaviors-llm-reinforcement-learning/) [Annual Meeting of the Association for Computational Linguistics (ACL)](https://md.research.elamur.ai/free/en/venues/acl/)**Zelin Tan, Hejia Geng, Xiaohang Yu, et al.*2026 · 6 citations* 4. **[Multiplayer Nash Preference Optimization ↗](https://arxiv.org/abs/2509.23102) arXiv (Cornell University) · no summary yet**Fang Wu et al.*2025 · 2 citations* 5. **[UniEvo-VL: An On-policy Self-Distillation Training Recipe for Multimodal Model Self-improvement ↗](https://arxiv.org/abs/2609.38721) arXiv (Cornell University) · no summary yet**Fang Wu et al.*2026* ## Co-authors here 7 co-authors with a page, the most papers together first. - [Guibin Zhang](https://md.research.elamur.ai/free/en/authors/guibin-zhang/) ×2 - [Kun Wang](https://md.research.elamur.ai/free/en/authors/kun-wang/) ×2 - [Yang Wang](https://md.research.elamur.ai/free/en/authors/yang-wang/) - [Yanwei Yue](https://md.research.elamur.ai/free/en/authors/yanwei-yue/) - [Yifan Zhou](https://md.research.elamur.ai/free/en/authors/yifan-zhou/) - [Yiyan Qi](https://md.research.elamur.ai/free/en/authors/yiyan-qi/) - [Zhong-Zhi Li](https://md.research.elamur.ai/free/en/authors/zhong-zhi-li/) ## Venues Where their works here were published, the most works first, with the editions of those that have a page. - [Annual Meeting of the Association for Computational Linguistics (ACL)](https://md.research.elamur.ai/free/en/venues/acl/) ×3: [ACL 2026](https://md.research.elamur.ai/free/en/venues/acl/2026/), [ACL 2025](https://md.research.elamur.ai/free/en/venues/acl/2025/) ×2 ## Cited by Papers of our library cite their works 48 times (of the 149,439 papers whose bibliographies we read); [17 citing papers with a page here →](https://md.research.elamur.ai/free/en/authors/guancheng-wan/cited-by/).
