The BBC ran a story on the work of Al Roth and Lloyd Shapley on an algorithm to solve the "stable marriage problem".  Given a group of men and women, is there a way of pairing them up such everyone has a "stable match", such that no pairings exist where both parties prefer each other rather than their current relationship.  UC Berkley has created an interactive website where you can walk through the steps and explore the process in depth.
