AgentFugue: Agent Scaling for Long-Horizon Tasks through Collective Reasoning
Yuyang Hu, Hongjin Qian, Shuting Wang, Jiongnan Liu, et al.
CoRR 2026
A collective reasoning framework that lets peer agents share reusable intermediate reasoning through a shared reasoning hub for long-horizon tasks.

SAM: State-Adaptive Memory for Long-Horizon Reasoning Agent
Yuyang Hu, Hongjin Qian, Shuting Wang, Jiongnan Liu, et al.
CoRR 2026
A state-adaptive memory framework that preserves raw trajectory pages while using compact memory cues for intent-driven recall in long-horizon agents.

MemSifter: Offloading LLM Memory Retrieval via Outcome-Driven Proxy Reasoning
Jiejun Tan, Zhicheng Dou†, Liancheng Zhang, Yuyang Hu, et al.
CoRR 2026
A proxy-reasoning framework that offloads LLM memory retrieval to a smaller model and optimizes retrieval through outcome-driven reinforcement learning.

Memory Matters More: Event-Centric Memory as a Logic Map for Agent Searching and Reasoning
Yuyang Hu, Jiongnan Liu, Jiejun Tan, Yutao Zhu, et al.
ACL Findings 2026
An event-centric memory framework that organizes agent experiences into an event graph for logic-aware memory search and reasoning.

Memory in the Age of AI Agents
Yuyang Hu*, Shichun Liu*, Yanwei Yue*, Guibin Zhang*, et al.
CoRR 2025
A comprehensive survey that organizes agent memory research through forms, functions, and dynamics, and summarizes benchmarks, frameworks, and future directions.

Investigating Users' Search Behavior and Outcome with ChatGPT in Learning-oriented Search Tasks
Sijie Liu, Yuyang Hu, Zihang Tian, Zhe Jin, et al.
SIGIR-AP 2024
A user study comparing traditional search, ChatGPT, and their combination for learning-oriented search tasks across different cognitive complexity levels.
