GenMem: Generative Symbolic Memory for Self-Evolving Harness

GenMem is presented, which reformulates memory management as generative symbolic addressing, a multi-level discrete token tuple drawn from a Cartesian-product address space that factorizes a million-scale sparse memory space using fewer than one hundred discrete symbols.

LoongReflect: Boosting Long-Horizon Reflection in Search Agents via Global Perspective Distillation

LoongReflect is proposed, a training framework that formulates reflection as a memory-control policy over a reversible trajectory tree using explicit reflect and backtrack actions and demonstrates consistent improvements over outcome-only reinforcement learning and self-distillation baselines.

ScaffoldAgent: Utility-Guided Dynamic Outline Optimization for Open-Ended Deep Research

ScaffoldAgent is proposed, a utility-guided dynamic outline optimization framework for OEDR that models outline evolution as a structured decision process with three operations: Expansion, Contraction, and Revision, enabling controlled updates to the report scaffold.

AgenticRag-R1: Agentic Reinforcement Learning with Stack Memory for Multi-Step Reasoning, Retrieval and Memorizing

This work proposes AgenticRag-R1, a RL framework that deeply integrates reasoning, retrieval, and memory via a memory stack and fine-grained action space, supported by hierarchical action-aware rewards and an information-aware trajectory rejection strategy to enable effective long-horizon learning.
