Plot 4 in Haskell

(Also called Connect 4)

This is the page for the game Plot 4 that I implemented in Haskell.

Plot 4

Plot 4, also called Connect 4, is a simple game. You have a grid (in our case with seven columns and six rows). There are two players, one having red coins and the other having yellow coins. The players take turns alternately to drop a coin in any column. The player who gets four of his coins in a line (vertical or horizontal or diagonal), wins.

This program provides four player modes.

\section {Motivation} I wrote this program when I got fascinated by game tree search. I wanted to try out the algorithm and see what results it shows. The game tree search routines have been implemented as a separate library (there's just one function there as I write this, but I plan to add more). The wonderful higher order nature of Haskell enables one to capture computational patterns in a higher order function. Therefore, the game tree search functions in the library can be used for any game with two players taking alternate turns.

A request

Please do give me any kind of feedback whatsoever, on the source or the game. Also, if you build the source on any platform, the binary for which is not available on this page, please do send the binary to me at srineet at yahoo dot com (written that way in the hope of tricking the automated spambots).
