Dictionary-Guided Mutation Operators for Automated HDL Repair

The paper introduces a dictionary-guided HDL repair system that uses ANTLR-derived mutation vocabularies and a simulation-divergence fault localization module to generate syntactically valid Verilog mutations. The mutation operator performs token substitutions, insertions, and deletions via regex matching, while the fault localization scores source lines based on proximity to diverging output wires, guiding the search. Evaluated on the CirFix benchmark, the approach achieves correct repairs on 14 bug variants, including a multi-bug case, and outperforms CirFix with an 18x speedup on a two-edit benchmark.

ReMCTS: Reflection-Enhanced Monte Carlo Tree Search for Code Generation

ReMCTS is a Monte Carlo Tree Search–style framework that enhances code generation by large language models (LLMs). It organizes program candidates as tree states, retains branch‑local debugging context, and retrieves failure experience across branches, distinguishing failed checks from unavailable evidence. Experiments on HumanEval and MBPP‑Sanitized show that visible‑test ReMCTS improves performance over direct generation in 8 of 10 model‑dataset pairs, while a pilot on HumanEval‑X C++ demonstrates compatibility with compiler‑backed execution.

ACTS-SQL: Agentic and Critic-Oriented Tree-Structured SQL Correctness with Large Language Models

arXiv:2608. 15145v1 Announce Type: new Abstract: Large Language Models (LLMs) have been increasingly adopted in Text-to-SQL systems, yet SQL errors remain a major obstacle in real-world Text-to-SQL inference pipelines.
