Overview

This novel algorithm combines large language models with surrogate-assisted evolutionary techniques, suggesting efficient optimization solutions.

Key Points

  • LLM-SAEA demonstrates improved optimization performance in costly tasks, outperforming state-of-the-art algorithms.
  • The approach utilizes large language models to dynamically select surrogate models and infill sampling criteria.
  • A collaboration-of-experts framework enables effective scoring and decision-making in the optimization process.
  • Experiments across standard test cases validate the method's efficiency and adaptability to various optimization scenarios.
