A new research paper titled "Lineage Is Memory: Parent Inheritance and Feedback Disclosure in Short-Budget LLM-Guided Optimization" explores the effectiveness of different optimization strategies for large language models. The study, conducted across 1,750 pre-registered runs on nine benchmarks, found that greedy parent inheritance, where revisions build upon a surviving parent, drives the majority of optimization progress. This method significantly outperforms seed-reset resampling, even when the latter receives more comprehensive failure feedback or uses larger models. While error clustering and diverse failure selection offer initial gains, sequential parent inheritance quickly matches their performance by retaining solved error modes. The research also highlights that the majority of computational cost in these optimization loops is consumed by validation and minibatch gating, rather than proposer reflection, suggesting that parent inheritance is a highly efficient method for achieving optimization gains.
