A new study analyzed the optimization trajectories of 15 large language models (LLMs) across eight tasks to understand how they perform within evolutionary search systems. The research found that while initial problem-solving ability is a factor, the way LLMs navigate the search space significantly impacts outcomes. Stronger LLM optimizers act as local refiners, making incremental improvements and staying focused, whereas weaker ones show more erratic progress with periods of stagnation. The study suggests that focusing on localized search, rather than just novelty, is key for improving LLM-based optimization. AI
