Combining Implicit and Explicit Reward Signals for Robust LLM-Generated Code Across Languages

Abstract

Abstract: This report synthesises findings from 13 peer-reviewed papers addressing the following research question: To what extent does combining implicit and explicit reward signals from unit tests improve the robustness of LLM-generated code across different programming languages on the MultiPL-E benchmark. Current large language models (LLMs) often struggle to produce accurate responses on the first attempt for complex reasoning tasks like code generation. Prior research tackles this challenge by generating multiple candidate solutions and validating them with LLM-generated unit. 9 claims were extracted from source literature; 3 were independently verified against retrieved documents. An automated multi-reviewer quality assessment produced a score of 5.5/10. This report is a machine-generated literature synthesis and does not constitute original research.
