Enhancing Genetic Improvement Mutations Using Large Language Models

1 code implementation18 Oct 2023 Alexander E. I. Brownlee, James Callan, Karine Even-Mendoza, Alina Geiger, Carol Hanna, Justyna Petke, Federica Sarro, Dominik Sobania

We find that the number of patches passing unit tests is up to 75% higher with LLM-based edits than with standard Insert edits.

no code implementations6 Apr 2023 William B. Langdon, Justyna Petke, Aymeric Blot, David Clark

By their very name caches are often overlooked and yet play a vital role in the performance of modern and indeed future hardware.

MAGPIE: Machine Automated General Performance Improvement via Evolution of Software

1 code implementation4 Aug 2022 Aymeric Blot, Justyna Petke

Our results show that, used independently, all techniques find significant running time improvements: up to 25% for compiler optimisation, 97% for algorithm configuration, and 61% for evolving source code using genetic improvement.
