Abstract
We analyze a class of proportional cakecutting algorithms that use a minimal number of cuts (n1 if there are n players) to divide a cake that the players value along one dimension. While these algorithms may not produce an envyfree or efficient allocationas these terms are used in the fairdivision literatureone, divideandconquer (D&C), minimizes the maximum number of players that any single player can envy. It works by asking n ≥ 2 players successively to place marks on a cakevalued along a linethat divide it into equal halves (when n is even) or nearly equal halves (when n is odd), then halves of these halves, and so on. Among other properties, D&C ensures players of at least 1/n shares, as they each value the cake, if and only if they are truthful. However, D&C may not allow players to obtain proportional, connected pieces if they have unequal entitlements. Possible applications of D&C to land division are briefly discussed.
