gym-saturation
gym-saturation is a collection of Gymnasium environments for reinforcement
learning (RL) agents guiding saturation-style automated theorem
provers (ATPs) based on the given clause algorithm.
There are two environments in gym-saturation following the same
API: SaturationEnv:
VampireEnv — for Vampire prover, and IProverEnv
— for iProver.
gym-saturation can be interesting for RL practitioners willing to
apply their experience to theorem proving without coding all the
logic-related stuff themselves.
In particular, ATPs serving as gym-saturation backends
incapsulate parsing the input formal language (usually, one of the
TPTP (Thousands of Problems for Theorem
Provers) library), transforming the input formulae to the clausal
normal form, and logic
inference using rules such as resolution and
superposition.

How to Install

Attention!
If you want to use VampireEnv you should have a
Vampire binary on your machine. For example, download the
latest release.
To use IProverEnv, please download a stable iProver
release or build it from this commit.

The best way to install this package is to use pip:
pip install gym-saturation
Another option is to use conda:
conda install -c conda-forge gym-saturation
One can also run it in a Docker container (pre-packed with
vampire and iproveropt binaries):
docker build -t gym-saturation https://github.com/inpefess/gym-saturation.git
docker run -it --rm -p 8888:8888 gym-saturation jupyter-lab --ip=0.0.0.0 --port=8888

How to use
One can use gym-saturation environments as any other Gymnasium environment:
import gym_saturation
import gymnasium

env = gymnasium.make("Vampire-v0") # or "iProver-v0"
# skip this line to use the default problem
env.set_task("a-TPTP-problem-filename")
observation, info = env.reset()
terminated, truncated = False, False
while not (terminated or truncated):
# apply policy (a random action here)
action = env.action_space.sample()
observation, reward, terminated, truncated, info = env.step(action)
env.close()

Related Projects
gym-saturation is compatible with RL-frameworks such as Ray
RLlib
and can leverage code embeddings such as CodeBERT.
Other projects using RL-guidance for ATPs include:

TRAIL
FLoP (see the paper for more details)
lazyCoP (see the paper for more details)

Other projects not using RL per se, but iterating a supervised
learning procedure instead:

ENIGMA (several repos, e.g. this one for
iProver; see the paper for
others)
Deepire
