Distributed Chess Engine

Description

Distributed chess engine, exploring and evaluating future possible moves to determine the best move to play.

Requirements

• Erlang: https://www.erlang.org/downloads
• Java: https://www.java.com/fr/download

Engine instructions

• In a terminal, run the java chess library node: java -jar game/game.jar <NODE>@<HOSTNAME> <COOKIE>, where <NODE> will be the name of the node,<HOSTNAME> is this machine hostname and <COOKIE> is a secret word used for Erlang communication between nodes.
• In DistributedChessEngine/ia/Open an Erlang terminal: erl -name <HOSTNAME> -setcookie <COOKIE>, where <HOSTNAME> is this machine hostname and with the same <COOKIE> as above.
• Compile the file ia.erl: c(ia)..

Function ia:master(javahost, depth, [fen]).

Start or resume a given game.

• javahost is the hostname of the running java chess library node, format: <NODE>@<HOSTNAME>
• depth is the number of moves ahead the program will look for
• fen is a given chess board disposition, in Forsyth–Edwards Notation (FEN). If not provided, the program will start a new game.

Linda tuple space test

• Start erlang in terminal with: erl -pa Linda-master/src
• And make sure that in the Linda-master/src folder for every .erl files you also have the corresponding .beam.
• Try to call with start position: "rnbqkbnr/pppppppp/8/8/8/8/PPPPPPPP/RNBQKBNR w KQkq - 0 1"
