protocol for dividing goods in a way that achieves proportional equitability. It can be generalized to more than 2=two people and is strategyproof. For three or more people it is not always possible to achieve a division that is both equitable and envy-free. The surplus procedure was devised by Steven J. Brams, Michael A. Jones, and Christian Klamler in 2006. A generalization of the surplus procedure called the equitable procedure (EP) achieves a form of equitability. Equitability and envy-freeness can be incompatible for 3 or more players.
