From Prompt Learning to SIPDO: The Closed‑Loop Evolution Driving Continuous Innovation

The article traces how prompt optimization has mirrored the historical evolution of parameter learning, outlines four development phases—from evolutionary search to beyond‑first‑order methods—and explains how SIPDO’s synthetic‑data feedback and difficulty‑progression create a closed‑loop system that yields consistent performance gains across LLM benchmarks.
