Web site helps you split almost anything fairly


Carnegie Mellon researchers have built Spliddit, a web site which gives users "provably fair" ways to divide things of value.

Dividing a cake using the "I cut, you choose" method is the classic example used to illustrate envy-free approaches. But even cake cutting can get mighty complicated, as the number of people sharing increases and as the division begins to account for additional factors — people who prefer icing to cake, people who prefer chocolate over vanilla, those who like cake decorations, etc.
