<Task>Find any research articles for the user prompt optimization based on RAG and LLM in the prompt engineering field, if there exists.</Task> 
<Constraints>**Do not invent or guess; 
**Look at the most recent papers from 2022-2026. 
**Search the internet for more recent papers. 
**Eliminate the results that focus only on prompt engineering techniques in LLMs, not prompt generation or augmentationt prompt generation or augmentaion or optimization.
**Return the full citation</Constraints> 
<Sample Example>A research paper on auto-prompting like GEPA: Reflective Prompt Evolution Can Outperform Reinforcement Learning (https://arxiv.org/abs/2507.19457)</Sample Example>
