Reversi-AI

AI Java program for playing Reversi, either against people or other AI agents.

Run a simple game

• Requires: Java 8.

• Clone the repo, for a simple game run the following in 3 different terminals:

java -cp "ReversiServer/" Reversi 3 
java -cp "ReversiHuman/" Human 127.0.0.1 2
java -cp "ReversiAI/" AI_Medium 127.0.0.1 1 

Windows batch files with various game settings are included for ease of use.

Custom games/difficulty

• The "Reversi" server program is neeeded to facilitate interactions between different players although it can be ran locally. It runs with 1 mandatory parameter representing the number of minutes before the game times out.

• The "Human" program allows user input to manually test the AI and play against it. It runs with 2 mandatory parameters: IP and Player Number.

• A number of different AIs are included with differing levels of skill. Descriptions are included below. All AI program runs with 3 parameters, the last one optional: IP, Player Number and depth representing the depth to which alpha/beta pruning is executed. The Easy, Medium and Hard levels have default depths they'll go until.

• The "Random" AI program runs 2 mandatory parameters: IP and Player Number and plays in a completely random fashion.It is included mostly for diagnostic purposes.

Parameters

• The IP address parameter should be 127.0.0.1 if all processes are ran locally.

• The accepted player number values are 1 or 2 representing the order of play respectively.

• The tree depth variable will quickly encounter memory constrainsts at a depth of 7 or more. A higher number leads to a stronger AI.

Windows

Have Java installed and click any of the bat files to run with that given specification.

Mac

From the root of the directory run the following commands in terminal.

1. java -cp "ReversiServer/" Reversi {NumberMinutesOfGame}
2. java -cp "ReversiAI_1/" {AI_LEVEL} {IP} {PlayerNumber} {OPTIONAL:TreeDepth}
3. java -cp "ReversiHuman/" Human {IP} {PlayerNumber}

Note that two different human players can play together with a running server and appropriate IP addresses.
