Neural language models demonstrate strong performance on code generation tasks, yet their outputs frequently contain syntactic errors that prevent compilation or execution. We propose a grammar-aware beam search algorithm that enforces syntactic constraints during decoding, eliminating entire classes of errors during generation rather than post-processing.

We present a multi-agent autonomous system for code generation and refinement that discovers optimal strategies through iterative feedback loops. Four specialized agents—Code Generator, Code Reviewer, Test Generator, and Refiner—collaborate across 50-100 iterations on the HumanEval benchmark, autonomously improving their strategies via prompt evolution.
