CPRet-Embeddings

This repository provides the problem descriptions and their corresponding precomputed embeddings used by the CPRet retrieval server.

You can explore the retrieval server via the online demo at https://cpret.online/.

📦 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:

🌐 Problem Sources (OJ)

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

🗂️ Versioning & Naming Convention

This repository uses a YYMM naming convention for dataset versions:

  • YY = last two digits of the year
  • MM = month

This repository keeps the latest version as well as historical versions of problem sets and embeddings for reproducibility and backward compatibility.
