Curated question–answer pairs are costly, and data selection alone cannot go beyond the pool that already exists. The authors instead generate new training items. Their pipeline has three steps: 3. **[Breaking the Impasse: Dual-Scale Evolutionary Policy Training for Social Language Agents](https://md.research.elamur.ai/free/en/papers/wang-2026-breaking-impasse-dual-scale-evolutionary/)** *(2026)* The paper looks at what goes wrong when self-play reinforcement learning with verifiable rewards (RLVR) moves from closed tasks like math or code to open-ended social language games. ## Co-authors here 12 of 14 co-authors with a page, the most papers together first. - [Chao Du](https://md.research.elamur.ai/free/en/authors/chao-du/) - [Hang Yan](https://md.research.elamur.ai/free/en/authors/hang-yan/) - [Jinjie Ni](https://md.research.elamur.ai/free/en/authors/jinjie-ni/) - [Lu Wang](https://md.research.elamur.ai/free/en/authors/lu-wang/) - [Min Lin](https://md.research.elamur.ai/free/en/authors/min-lin/) - [Minzheng Wang](https://md.research.elamur.ai/free/en/authors/minzheng-wang/) - [Nan Xu](https://md.research.elamur.ai/free/en/authors/nan-xu/) - [Run Luo](https://md.research.elamur.ai/free/en/authors/run-luo/) - [Tianyu Pang](https://md.research.elamur.ai/free/en/authors/tianyu-pang/) - [Wee Sun Lee](https://md.research.elamur.ai/free/en/authors/wee-sun-lee/) - [Wenji Mao](https://md.research.elamur.ai/free/en/authors/wenji-mao/) - [Wenjun Li](https://md.research.elamur.ai/free/en/authors/wenjun-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/): [ACL 2026](https://md.research.elamur.ai/free/en/venues/acl/2026/) - [Findings of the Association for Computational Linguistics](https://md.research.elamur.ai/free/en/venues/findings/): [Findings of the Association for Computational Linguistics 2026](https://md.research.elamur.ai/free/en/venues/findings/2026/) ## Cited by Papers of our library cite their works 281 times (of the 149,439 papers whose bibliographies we read); [71 citing papers with a page here →](https://md.research.elamur.ai/free/en/authors/zichen-liu/cited-by/).
