Chess AI using Alpha-Beta Pruning

Overview

This Chess AI was built using the Alpha-Beta Pruning algorithm to optimize the Minimax decision-making process. The AI evaluates board positions and makes efficient moves by pruning unnecessary branches in the search tree, improving performance.

Features

Implements Alpha-Beta Pruning to enhance Minimax efficiency.
Supports basic chess rules and move generation.
Written in Python for ease of use and modification.
Can play against a human player or another AI instance.

Installation

Ensure you have Python installed, then clone the repository:
git clone https://github.com/nathanaelmbale/Chess-Ai.git
cd Chess-Ai
Install dependencies :
pip install -r requirements.txt

Usage

Run the script to start the AI:
python ChessMain.py
Modify depth in the code to adjust the AI’s difficulty level.

How It Works

The AI uses:
Minimax Algorithm – To determine the best possible move by evaluating future positions.
Alpha-Beta Pruning – To eliminate unnecessary calculations and speed up decision-making.
Evaluation Function – To assess board states based on material, position, and other heuristics.

Future Improvements

Implement a GUI using Pygame or Tkinter.
Improve the evaluation function for better strategic play.
Add support for opening books and endgame databases.
Using a library like Tensorflow to train the Ai
