A long, long time ago back in 2002 (which in computer terms equals to an eternity and when my internet connection ran at a whooping 4KB/s), I was asked to write a solver for the Mastermind game.
It uses the Greenwell keys, whose answers allowed to readily solve the game after the 6th answer. It was written fully in Haskell and it was The "first" real project that I have done for my BSc.
This is the main reason I include it here, not for its quality, but for what it personally represents. Also all the code is written with Portuguese function names which adds more weight to the memorabilia factor.
For more information take a look in https://en.wikipedia.org/wiki/Mastermind_(board_game)
The Mastermind answers provided by the Greenwell keys, provide unique non-ambigous information used to indentify the secret code of the game. These are the main "trick" for the whole project.
[ [1,2,2,1], [2,3,5,4], [3,3,1,1], [4,5,2,4], [5,6,5,6], [6,6,4,3] ]For more information on the Greenwell keys see: http://www.cut-the-knot.org/ctk/Mastermind.shtml
Install the Haskell interpreter and point to the MM module.
