A proportional cake-cutting is a kind of fair cake-cutting. It is a division of a heterogeneous resource ("cake") that satisfies the proportionality criterion, namely, that every partner feels that his allocated share is worth at least 1/n of the total. Two assumptions are usually made when proportionality is discussed: * The valuations of the partners are non-atomic, i.e., there are no indivisible elements with positive value. * The valuations of the partners are additive, i.e., when a piece is divided, the value of the piece is equal to the sum of its parts. (Wikipedia).
