Connect Four Game with NEAT AI

This project implements a Connect Four game with multiple AI opponents using Python, Pygame, and NEAT (NeuroEvolution of Augmenting Topologies). The game features various play modes and an evolving AI that learns to play Connect Four.

Features

Classic Connect Four gameplay
Multiple game modes:
- Human vs. Human
- Human vs. AI (Minimax)
- Human vs. NEAT AI
NEAT-based AI that evolves with each generation

Project Structure

The project consists of the following main components:

baseGame.py: Implements the core Connect Four game logic
gameGUI.py: Handles the game's graphical user interface
engine.py: Contains the minimax AI engine
neat_player.py: Implements the NEAT AI player
neat_trainer.py: Trains the NEAT AI
connect4_config.txt: Configuration file for NEAT

Requirement

Required dependencies:

pip install pygame neat-python

Usage

Train the NEAT AI (a pre-trained model is provided in best_connect4_ai.pkl):
```
python neat_trainer.py
```
Run the game:
```
python gameGUI.py
```

Use the mouse to select columns and drop pieces. Press 'R' to restart the game, 'Q' to quit, 'M' to change game modes, and 'E' to toggle AI evaluation display.

AI Implementation

The minimax AI uses alpha-beta pruning for efficient decision-making.
The NEAT AI evolves neural networks to play Connect Four, improving over generations.
