# Web site helps you split almost anything fairly

But how can this site take into account just how much (more) I deserve?

The āI cut, you chooseā method was the classic way to divide a weed bag fairly and ensure everyone got the same amount of herb. You know, back when it was illegal. Oh, itās still illegal in your state? Iām so sorry to hear that.

No, but this site can.

This looks like they took the general ideas of the estate division chapter of Neal Stephensonās Cryptonomicon and ran with it into a fully operational system.

Krypton will always be envious of Barium

Many think the source of the word āatomā is ānot divisibleā, but scholars of ancient Greek agree that in contemporary contexts, it meant ānot divisible fairlyā.

Decorations are an interesting question, but my favorite scales-to-any-number-of-people solution to cake cutting it in http://www.amazon.com/How-Cut-Cake-Mathematical-Conundrums/dp/0199205906

1. Make a single cut.
2. Life the knife and slowly rotate clockwise.
3. At any time, anyone may say āCut.ā
4. When they do, make a cut, and that person who spoke gets the piece.

At the end, anyone who thinks their piece is too small must think someone elseās is too large, so they could have said ācutā before it got that large. Or, they think there wasnāt enough cake in the first place, which is not a problem that any division method can solve.

I was thinking just that. Although itās a little more complicated for the cases with both benefit and cost (they only show that as āSplitting Rentā, but it could be generalized to many more things), because instead of just saying how much you want something, you say how much youād be willing to pay for it. So itās maximizing two variables, your desire and the amount of money you ultimately end up spending.

That seems a much better method than the generalized n>2 method I always heard for cutting cake fairly.

The method I heard was that person A cuts a slice. Then person B either cuts a new slice, or cuts a slice out of Aās. Each person moving forward can cut a slice from the cake or from anyone elseās slice.

The problem with this method that I never saw mentioned is that it doesnāt solve the problem of being a dick. To wit: Person A precisely cuts a 1/nth piece, and then Person B cuts himself 99% of Aās slice just to be a dick.

You solution doesnāt seem to allow that.

(Perhaps my version could be amended by allowing multiple rounds until it all settles. But I think the existence of the dick may preclude the possibility of settling.)

Cupcakes.
