This project implements a classic Connect 4 game in Python, featuring a graphical user interface provided by Pygame and an AI opponent powered by a minimax algorithm with alpha-beta pruning and iterative deepening. The AI's strategy is based on evaluating the game board to make intelligent moves against the player.

Python 3.x

Pip (Python package installer)

Install the required Python packages using pip:

pip install pygame numpy

Running the Game
To start the game, navigate to the project directory and run the following command in your terminal:

bash
Copy code

python connect4.py  

Make sure to replace connect4.py with comparison and my_connect4_ai to use those instead.

The game is played on a vertical board consisting of 6 rows and 7 columns.
Two players take turns dropping colored discs into the columns of the board.
The first player to align four discs vertically, horizontally, or diagonally wins the game.
If all columns are filled and no player has achieved a line of four, the game is a draw.

Graphical User Interface: Utilizes Pygame for rendering the game board and handling user interactions. AI Opponent: Employs a minimax algorithm with enhancements such as alpha-beta pruning for efficiency and iterative deepening for improved decision-making.
Dynamic Board Evaluation: The board is dynamically evaluated after each move to update the game state and determine the winner.
