On: Self-Enforcing Protocols

This assumes that the cake is uniform, and most cakes aren't.

If the cutter prefers frosting and knows that the other person doesn't, the cutter can arrange to get a larger share than she'd get if roles were reversed.

I think that the problem can be fixed by giving all participants knives so they're all cutters.

I'm assuming this algorithm isn't: "Give each party a knife. Survivor gets the cake."

That works too.

However, I was trying to say "everyone does the moving knife thing and anyone can call the cut on anyone's knife".
