Evaluating QAOA expectation values can be as hard as counting optimal solutions

Stuart Hadfield

Evaluating expectation values is a critical task for variational quantum eigensolvers, and for parameterized quantum circuits and other quantum algorithms more generally. We consid…

Coupling Planning with Episodic Memory in LLM Agents for Software Issue Resolution

Jiahao Zhang, Yifan Zhang, Yu Huang

Resolving a real software issue with a large language model (LLM) agent is a long repair episode, often tens to hundreds of steps spanning exploration, hypothesis, implementation,…

SCOPE: Leveraging Subgoal Critiques for Code Generation

Yueke Zhang, Yifan Zhang, Zihan Fang +3

Code generation with large language models (LLMs) remains unreliable because generated programs can appear correct while still violating key semantic requirements in the natural la…

DPO-F+: Aligning Code Repair Feedback with Developers' Preferences

Zihan Fang, Yifan Zhang, Yueke Zhang +2

Large Language Models (LLMs) are increasingly used in software engineering tasks, especially code repair. However, developers often struggle to interpret model outputs, limiting ef…

SynthFix: Adaptive Neuro-Symbolic Code Vulnerability Repair

Yifan Zhang, Jieyu Li, Kexin Pei +2

Large Language Models (LLMs) can generate plausible code patches, but plausibility is not enough for automated repair: a patch must compile, pass tests, and remove the target vulne…

VERITAS: Verifier-Guided Proof Search for Zero-Shot Formal Theorem Proving

Manish Acharya, Zhenyu Liao, Yueke Zhang +3

LLM-based formal provers often collapse rich verifier signals (syntax errors, type mismatches, partial goal progress) into a binary pass/fail bit. We present VERITAS, a zero-shot f…
