Relay, Don't Route: Adaptive Population Handoff for Cost-Efficient LLM-Driven Evolution
A recent study published on arXiv (2608.05651) presents a technique named 'Relay, Don't Route' aimed at enhancing the cost-effectiveness of LLM-driven evolution. The researchers note that evolutionary search is characterized by its stateful nature and that initial trajectory performance, though informative, tends to be noisy. They suggest a framework that eliminates the need for training, reallocating resources from single calls to evolving populations. This allows for a transition between less expensive and more powerful models within a set inference budget. The goal of this method is to lower expenses while preserving performance in tasks related to program search and algorithm discovery.
