On adaptive specialisation in genetic improvement

2019 · Proceedings of the Genetic and Evolutionary Computation Conference Companion

Genetic improvement uses automated search to find improved versions of existing software. Software can either be evolved with general-purpose intentions or with a focus on a specific application (e.g., to improve it's efficiency for a …

Large language model based mutations in genetic improvement

2025 · Automated Software Engineering

Abstract Ever since the first large language models (LLMs) have become available, both academics and practitioners have used them to aid software engineering tasks. However, little research as yet has been done in combining search-based …

Enhancing Software Runtime With Reinforcement Learning-Driven Mutation Operator Selection in Genetic Improvement

2025

Genetic Improvement employs heuristic search algorithms to explore the search space of program variants by modifying code using mutation operators. This research focuses on operators that delete, insert and replace source code statements. Traditionally, in …
