What papers say

Verbatim critique sentences, each from a paper that cites Memory-R1 as a baseline.

Memory-R1 introduces a comprehensive forgetting mechanism similar to the one we propose, but lacks any kind of temporal encoding in its stored memories.
Mnemosyne: An Unsupervised, Human-Inspired Long-Term Memory Architecture for Edge-Based LLMs
While Memory-R1~memoryr1 advances this by using reinforcement learning to optimize storage and retrieval policies, its retrieval is still a single-round process.
General Agentic Memory Via Deep Research
In long-term dialogues, a single reward given at the end of a multi-session trajectory is too sparse.
MemBuilder: Reinforcing LLMs for Long-Term Memory Construction via Attributed Dense Rewards
However, they rely mainly on outcome-level rewards and do not explicitly address cross-session credit assignment under diverging memory states.
Memory-R2: Fair Credit Assignment for Long-Horizon Memory-Augmented LLM Agents
