On EnterpriseRAG-Bench, MEMONDEMAND outperforms the strongest published LB#1 result at every evaluated scale from 10M tokens through the complete 618M- token collection, and results on FinanceBench, HotpotQA, and FRAMES further show strong performance across financial, multi-hop, and fact-retrieval settings.

These results show that MegaMem supports ultra-large persistent memory while preserving strong answer accuracy under a bounded generation context, and provides a practical path toward accurate retrieval over memories ranging from hundreds of millions to one billion tokens.

AlGOBENCH is introduced, a framework that automatically builds novel algorithmic problems from known competitive-programming problems through structured constraint-shifting transformations and error analysis shows that failures are mainly algorithmic rather than implementation-level, suggesting that ALGOBENCH evaluates...
WM-SAR, a spectral subgraph repair method that estimates node-edge amplification, greedily grows a connected repair region by marginal residual-spectral relief, and sends only this region to an LLM for root-cause repair, achieves stronger long-horizon stabilization and root-cause recovery under compact token budgets.
Grounded Iterative Language Planning (GILP), which trains only a small parameterized backbone and combines it with API-based agent reasoning, and a consistency gate asks for revision when the two disagree are compared.
Large language model (LLM) agents are usually improved by changing prompts, models, or hand-written workflows, while the execution harness around the model is treated as fixed infrastructure. We argue that this harness is itself a learnable control layer. We formalize harness operation as a finite-horizon Harness MDP,...
Experiments on competitive programming and combinatorial optimization benchmarks show that AlgoSkill improves over direct LLM generation, chain-of-thought prompting, self-refinement, and MCTS without typed skills, which support treating automatic algorithm design as verification-guided skill scheduling rather than one-...

A belief-rollout diagnostic is introduced that elicits structured K-step trajectories over progress, risk, recoverability, constraints, failure mode, uncertainty, future success, repair cost, and next action under alternative harnesses and suggests that harness design is an experimental variable in agent evaluation, no...
