[Haskell-cafe] river crossing puzzle

[pat browne]

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:

Thanks,
Pat
