Introduction

We introduce GAR: Generative Adversarial Reinforcement Learning, an RL training method that intends to solve inefficiency and suboptimial performance in formal theorem prover training caused by fixed problem sets. GAR jointly trains the problem composer and solver in an adversarial loop, which introduces an implicit curriculum learning mechanism, aligning the task difficulty with the prover's evolving capability to improve training efficiency and enabling stronger model performance.

Experiments indicates that GAR trained models (such as Goedel-Prover-V2-8B and DeepSeek-Prover-V2-7B) achieve an average of 4.20% of enhancement on MiniF2F-Test under pass@32, and improve the DeepSeek-Prover-V2's pass@32 performance on ProofNet-Test from 22.58% to 25.81%.

Training Guide

Clone repository

Clone the repo using the following command:

git clone --recurse-submodules [email protected]:RickySkywalker/GAR-Official.git

Init Lean server

We apply KiminaLeanServer as the Lean verification server. It can be initialized by:

cd KiminaLeanServer
cp .env.template .env
docker compose up -d

Setup environment

The environment can be set up by running the following command:

conda env create -f environment.yaml

Clone base dataset

Clone and transform the dataset into JSON form:

from datasets import load_dataset
ds = load_dataset("RickyDeSkywalker/GAR_baseDataset_NuminaMath")
ds["train"].to_json("./base_data/GAR_base_data_Numina-Math.json")

Run training

The GAR training can be initialized through the following command, detailed training config can be found in ./main.py.

python -u ./main.py \
    --training_name GAR-Prover \
    --base_data_path ./base_data/GAR_base_data_Numina-Math.json
