divide and choose
Divide and choose (also Cut and choose or I cut, you choose) is a procedure for envy-free cake-cutting between two partners. It involves a heterogeneous good or resource ("the cake") and two partners which have different preferences over parts of the cake. The protocol proceeds as follows: one person ("the cutter") cuts the cake to two pieces; the other person ("the chooser") chooses one of the pieces; the cutter receives the remaining piece.
==History==
Divide-and-choose is mentioned in the Bible, in the Book of Genesis (chapter 13). When Abraham and Lot come to the land of Canaan, Abraham suggests that they divide it among them. Then Abraham, coming from the south, divides the land to a "left" (western) part and a "right" (eastern) part, and lets Lot choose. Lot chooses the eastern part which contains Sodom and Gomorrah, and Abraham is left with the western part which contains Beer Sheva, Hebron, Beit El and Shechem.
