Chess Game (with AI) in Haskell

Chesssimple

Chesssimple is a very simple Chess game that implements almost all the chess rules and includes a very simple AI. The purpose of this project is to learn Haskell and functional programming concepts; in fact, this was my project of a semestral functional programming course at UNLP.

Instalation and execution:

./chesssimple> cabal update
./chesssimple> cabal install
./chesssimple> ./dist/build/chesssimple/chesssimple

Executable options and help

There are 3 game modes with their own options:

• hvc: Human vs Computer (default)
• hvh: Human vs Human
• cvc: Computer vs Computer

The Chesssimple program

Chesssimple [COMMAND] ... [OPTIONS]
  Chess game & engine

Common flags:
  -? --help            Display help message
  -V --version         Print version information

Chesssimple hvh [OPTIONS]

     --p1name=ITEM     The player 1's name
     --p1color=ITEM    The player 1's color
     --p2name=ITEM     The player 2's name

Chesssimple [hvc] [OPTIONS]

     --hname=ITEM      The human player's name
     --hcolor=ITEM     The human player's color
  -c --cstrength=INT   The computer player's strength

Chesssimple cvc [OPTIONS]

     --p1strength=INT  The player 1's strength
     --p2strength=INT  The player 2's strength

For instance:

./dist/build/chesssimple/chesssimple hvc --cstrength=2 --hcolor=black

Will start a game where human player will be the black team and computer game will have a strength of 2 (very easy)

Execution with threads:

Add these parameters to the chesssimple command: +RTS -Nt, where t is the number of threads. For example:

./chesssimple> ./dist/build/chesssimple/chesssimple hvc --cstrength=2 --hcolor=black +RTS -N4

Will start a game with 4 threads.

Tests

Run it with:

./chesssimple> ghci < runtests

More docs:

There is a .tex file which contains technical information of Chesssimple (only in Spanish)

TODOs:

• Implement castling
• Implement in passant rule
• Implement a better piece promotions
• Add and improve all tests suit.
