Or you could look at my blog posts describing the implementation of the
Cannibals and Missionaries variant step by step.
First a naive approach and secondly using a state monad solution.

Hi, Does anyone know where there are any Haskell implementations of the the River Crossing puzzle (AKA Farmer/Fox/Goose/Grain). There are several variations but the general ideas are explained at: http://en.wikipedia.org/wiki/River_crossing_puzzle http://en.wikipedia.org/wiki/Fox,_goose_and_bag_of_beans_puzzle
I have found one at: http://www.shido.info/hs/haskell9.html
Thanks, Pat
