SATQuest 0.2.0

A Verifier for Logical Reasoning Evaluation and Reinforcement Fine-Tuning of LLMs

SATQuest: A Verifier for Logical Reasoning Evaluation and Reinforcement Fine-Tuning of LLMs

🧰 What's Inside

• CNF-based problems spanning three orthogonal dimensions: instance scale, problem type, and question format.
• A PySAT-backed verifier that scores binary answers and exposes solver metadata for reproducible diagnostics.
• Ready-to-use datasets on Hugging Face, evaluation scripts, and RFT scripts.

⚡ Quickstart

# Install dependencies
# pip install datasets satquest

from datasets import load_dataset

from satquest import CNF, create_problem, create_question

item = load_dataset("sdpkjc/SATQuest", split="test")[0]
cnf = CNF(dimacs=item["sat_dimacs"])
# cnf.shuffle()

problem = create_problem("SATSP", cnf)  # or 'SATDP', 'MaxSAT', 'MCS', 'MUS'
question = create_question("math")  # or 'dimacs', 'story', 'dualstory'

prompt = problem.accept(question)
"""
Given a CNF formula with 3 variables and 12 clauses in mathematical notation:

(x_1 \lor x_2 \lor x_3) \land (x_3 \lor \neg x_1 \lor x_2) \land (x_1 \lor x_3 \lor \neg x_2) \land (x_1 \lor \neg x_2) \land (x_3 \lor x_1 \lor \neg x_2) \land (x_3 \lor \neg x_1 \lor x_2) \land (\neg x_3 \lor \neg x_1) \land (\neg x_1 \lor x_2 \lor x_3) \land (\neg x_2 \lor \neg x_3) \land (\neg x_2 \lor x_3 \lor x_1) \land (x_1 \lor \neg x_3) \land (\neg x_3 \lor \neg x_2 \lor \neg x_1)

Find a satisfying assignment for the formula.
Output a binary string of length 3 ('1' for true, '0' for false).
"""

answer = problem.solution  # reference answer
# 110

reward = int(problem.check(answer))  # 1 if answer is correct, 0 otherwise, 0.5 if answer is partial
# 1

🏭 Dataset Generation

# Run dataset generation
uv run --group gen gen_cnf_dataset.py --hf-entity {YOUR_HF_ENTITY} --seed 9527

uv run --group gen gen_cnf_rft_dataset.py --hf-entity {YOUR_HF_ENTITY} --seed 9527

📊 Evaluation

# Run evaluation
uv run --group eval eval_model.py \
    --exp-name {YOUR_EXP_NAME} \
    --wandb-project "SATQuest-Eval" \
    --hf-dataset-name "sdpkjc/SATQuest" \
    --p-type-list SATSP \
    --q-type-list math \
    --llm-model "gpt-4o" \
    --max-tokens 16384 \
    --temperature 0.6 \
    --num-example 10 \
    --stream True \
    --cnf-shuffle False \
    --n-repeat 1

The evaluation results will be logged to Weights & Biases.

🏄 Reinforcement Fine-Tuning (RFT)

# Run RFT training
