mancala-engine's Introduction

Mancala Engine

Overview

This program was created for the purpose of finding strong moves in the strategy board game Mancala.

It uses the minimax algorithm with alpha-beta pruning to search the tree of possible game states up to a certain depth (default 24) and return the best move along with an evaluation number. When this number is positive the engine is winning, and when it is negative the human player is winning.

Build Instructions

Make sure you have CMake and a C++ Compiler installed.

cd mancala-engine
mkdir build
cd build
cmake ..
cmake --build .
./MancalaEngine

Testing

This project uses the GoogleTest framework. After following the build commands above, you can simply run

ctest

while in the build directory.
