ImprovEvolve: Basin-Hopping Meets LLM-Guided Evolutionary Search

arXiv:2602.10233v2 Announce Type: replace-cross Abstract: LLM-guided evolutionary computation, most notably AlphaEvolve, has been remarkably successful in discovering novel mathematical constructions by solving challenging optimization problems. The standard approach is to evolve a monolithic program that directly outputs a candidate solution. We present ImprovEvolve, an algorithmic alternative that drastically reduces cognitive load on the LLM. Instead of prompting the model for an end-to-end optimizer, we evolve a program with three specialized operators of initialization, local improvement,

Why this matters
Why now

The continuous evolution of Large Language Models (LLMs) and their application in problem-solving necessitates more efficient integration methods, leading to innovations like ImprovEvolve. This work builds on the success of earlier LLM-guided evolutionary computation.

Why it’s important

This development represents a significant step in optimizing LLM utility for complex problem-solving, reducing the computational and cognitive load associated with creating end-to-end optimizers. It will accelerate the discovery of novel mathematical constructions and solutions to challenging optimization problems.

What changes

Instead of full end-to-end programming, LLMs will be guided to evolve specialized operators for initialization, local improvement, and perturbation, making their application in evolutionary computation more modular and efficient. This modular approach significantly lowers the barrier for designing sophisticated problem-solvers.
