PACEvolve++: Improving Test-time Learning for Evolutionary Search Agents

Minghao Yan, Bo Peng, Benjamin Coleman +11

Large language models have become drivers of evolutionary search, but most systems rely on a fixed, prompt-elicited policy to sample next candidates. This limits adaptation in prac…
