Gym Environment for SpaRC Project

---

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/ .

Arguments when creating the Gym Env:

• puzzles(pd.DataFrame) The puzzles that should be used. The puzzles must come in the shape of https://sparc.gipplab.org/ .
• render_mode(str) Optional, If render_mode='human' the Gym Environment will visualize every step using pygame. If no argumentpassed: no render mode activated.
• traceback (bool) When set to True it allows the Agent to move back on his path, if False it does not. If argument not passed: traceback=False.
• max_steps(int) Optional, the maximum amount of steps the Gym environment will runbefore it terminates. If no argument passed: max_steps=200.

Installation and Usage

how to use:

• Either:
  • Run pip install Gym-Env-SPaRC
  • import gymnasium_env_for_SPaRC (and gymnasium)
  • make the gym using: env = gym.make("env-SPaRC-v0", puzzles=df, render_mode='human', traceback=False, max_steps=max_steps) (example)
  • and use the gym to your liking, examples how to use are in Final_Product.py or llm_host.py
• or:
  • clone the repository
  • install the dependecies
  • Run Final_Product.py to play as a human or customize Final_Product.py or llm_host.py to your liking

Environment Details

Action Space

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

Observation Space

• 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

Reward System

• Sparse Rewards:

  • Outcome Reward:
    • +1: For solving the puzzle.
    • 0: For intermediate steps.
    • -1: for Failing.
  • Normal Reward:
    • +1: For solving the puzzle.
    • -1: For Failing.
    • +0.01: For staying on a solution path on each step.

• Note: The Reward from the step function is the Normal Reward, Outcome Reward can be found in the Info if needed.

Visualization

The environment uses pygame for rendering:

• Agent: Blue square.
• Target: Red square.
• Gaps: Dark Green cells.
• Visited cells: light Green cells.
• Unique Properties:
  • Stars: colored star.
  • Square: colored square.
  • Triangles: Colored triangles with counts.
  • Polyshapes: Colored polygons.
  • Ylop: Colored Polygons with marker ylop.
  • Dots: Small black circles.
