Gym Environment for SpaRC

---

Description

A custom Gymnasium environment for SPaRC. The Game and Dataset was develop by: https://sparc.gipplab.org/ . This project allows LLM agents and humans to interact/play the puzzles used in SPaRC. For how the puzzles work also look up https://sparc.gipplab.org/ .

Installation

📦 PyPI Package

Install the package from PyPI:

pip install Gym-Env-SPaRC

Or install from source:

git clone https://github.com/tobiTKM/Gym-Environment_for_SPaRC.git
cd Gym-Environment_for_SPaRC
pip install -e .

Quick Start

To create the Gym Environment:

import gymnasium as gym
import gymnasium_env_for_SPaRC
env = gym.make("env-SPaRC-v1", puzzles=df, render_mode='human', observation='new',traceback=True, max_steps=1000)

Options

Option	Default	Options	Description
puzzles	required	pd.Dataframe	Pandas DataFrame of SPaRC puzzles
render_mode	None	'human', 'llm', or None	Which Visualization to use
observation	'new'	'new' or 'SPaRC'	Which Observation type to use
traceback	False	False or True	Allow the agent to backtrack
max_steps	2000	any int	Maximum steps per episode

Core Functions

env.reset() -> Observation, Info: dict

Resets the Environment, moves to the next puzzle. Returns the Initial Observation and Info.

env.step(action: int(0-3)) -> observation, reward: int, terminated: bool, truncated: bool, info: dict

Moves the Environment one Step based on the Action. Returns the new Observation, Info, Reward and if the puzzle is finished.

env.render()

Visualizes the Puzzle's current State

env.close()

Close the environment and cleanup any resources.

Environment Details

Action Space

• Discrete(4): Represents the four possible moves:
  • 0: Right
  • 1: Up
  • 2: Left
  • 3: Down

Observation Space

if Observation = 'new':

• Dict A Dictionary of:
  • base: Dict: A dictionary of 2D arrays representing the puzzle state:
    • "visited": Tracks visited cells.
    • "gaps": Represents gaps in the grid.
    • "agent_location": Current position of the agent.
    • "target_location": Goal position.
    • Additional keys for unique properties like "stars", "triangles", etc.
    • The 2D Arrays are of the shape of the puzzle and are One-hot Encoded
  • color: list: A 2D Array representing the colors of the properties.
    • 8 possible colors are represented with 1-8
    • 2D Array is of shape of the puzzle
  • additional_info: list A 2D Array with additional Info about the puzzle
    • 2D Array is of shape of the puzzle
    • Possible additional_info:
    • ID of the polyshape
    • Count of the Triangles

if Observation = 'SPaRC':

• Json String Same Representation as in SPaRC https://github.com/lkaesberg/SPaRC . Json String Representation of a 2D array of the grid capturing all different properties as Symbols (Strings).

Reward System

• Sparse Rewards:
  • +1: For solving the puzzle.
  • -1: For Failing.
  • +0.01: For staying on a solution path on each step.
