📦 Files

—probs_2606.jsonl A JSONL file containing natural language descriptions of competitive programming problems. Each line is a JSON object with metadata such as problem title, platform/source OJ, URL, and full description.

—probs_2606_embs.npy A NumPy array of dense embeddings corresponding to each problem in probs_2606.jsonl. These embeddings are generated using the model coldchair16/CPRetriever-Prob-Qwen3-4B-2510.

🧠 Embedding Model

The embeddings in this repository are computed with:

—coldchair16/CPRetriever-Prob-Qwen3-4B-2510

🌐 Problem Sources (OJ)

The current 2606 problem set includes problems from the following online judges:

Data snapshot: June 2026.
