Beyond Semantic Organization: Memory as Execution State Management for Long-Horizon Agents

Yaoqi Chen, Haibin Lai, Yuru Feng +12

LLM-based agents increasingly tackle long-horizon tasks with interdependent decisions, where each action reshapes future constraints and intermediate errors can cascade. Existing R…
