On seven GLUE natural-language-understanding tasks, the authors report better results than existing baselines. For teams tuning prompts against measurable objectives, it is a research lead on how to spend a fixed search budget.","published_at":"2026-11-10","updated_at":"2026-11-10","record_date":"2026-11-10","date_kind":"published_at","topics":["prompts"],"entities":["Yu Cai","Canxi Huang","Xiaoyu He","GLUE"],"related_patterns":[],"novelty_label":"new_fact","what_changed":"A new projection-free evolutionary strategy searches the full prompt space and reportedly beats existing baselines on seven GLUE tasks without extra computational overhead.","prior_refs":[],"source_url":"https://arxiv.org/abs/2603.13786","source_urls":["https://arxiv.org/abs/2603.13786"],"schema_version":"newruntime-agent-readable-v0.2","stable_id":"post:new-projection-free-evolution-strategy-for-black-box-575113","status":"published","visuals":[],"editor":{"role":"editor","name":"Andrey Reshetnikov","profile":"https://newruntime.com/owner-profile.md","profile_json":"https://newruntime.com/owner-profile.json","same_as":["https://www.linkedin.com/in/reshetnikov1/","https://t.me/lapetuse"]},"routes":{"html":"https://newruntime.com/posts/new-projection-free-evolution-strategy-for-black-box-575113/","markdown":"https://newruntime.com/posts/new-projection-free-evolution-strategy-for-black-box-575113.md","json":"https://newruntime.com/posts/new-projection-free-evolution-strategy-for-black-box-575113.json"},"markdown_url":"https://newruntime.com/posts/new-projection-free-evolution-strategy-for-black-box-575113.md","next_reads":[{"type":"topic","path":"/topics/prompts/","url":"https://newruntime.com/topics/prompts/","title":"Prompts","reason":"Explore the prompts topic hub.","media_type":"text/html","markdown_url":"https://newruntime.com/topics/prompts.md","json_url":"https://newruntime.com/topics/prompts.json"},{"type":"collection","path":"/posts/","url":"https://newruntime.com/posts/","title":"Field Notes","reason":"Open the latest editorial analysis.","media_type":"text/html","json_url":"https://newruntime.com/posts.json"},{"type":"collection","path":"/sources/","url":"https://newruntime.com/sources/","title":"Sources","reason":"See the original sources this archive cites.","media_type":"text/html"}]}
