# SE-Search-3B

*Self-Evolving Search Agent via Memory and Dense Reward*

## 🔥 News

- Paper available on \[[ArXiv](https://arxiv.org/pdf/2603.03293)\]

## 📖 Overview

SE-Search is a Self-Evolving Search agent that improves online search behavior through a **Think-Search-Memorize** strategy:

- **Memory Purification**: Retains salient evidence while filtering irrelevant content
- **Atomic Query**: Promotes shorter and more diverse queries, improving evidence acquisition
- **Dense Rewards**: Provides fine-grained feedback that speeds up training and improves performance
