Robin Wilson, Gresham Professor of Geometry, gives a quick run-through of the origins of the river-cross problem and the basis of how to solve it.

Many more explanations of various puzzles can be found on the Gresham College website. How do you get the fox, the goose, and the bag of corn across the river without any of them being eaten? Were the rules of means-end analysis applied to the solving of this problem?
