When Do Causal World Models Help Modular LLM Agents

FedCausalCompose, a causal world-model framework for modular LLM agents in which local actions provide intervention-response evidence for cross-module interfaces, identifies a concrete condition for causal world models in LLM agents: causal structure helps when cross-module interfaces are both statistically identifiabl...

AlgoBench: Benchmarking Algorithmic Adaptation in Code Generation

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...

Repair the Amplifier, Not the Symptom: Stable World-Model Correction for Agent Rollouts

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.

AlgoSkill: Learning to Design Algorithms by Scheduling Human-Like Skills

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-...
