切蛋糕不可分割的代价

The Price of Indivisibility in Cake Cutting

Eshwar Ram Arunachaleswaran, Ragavendran Gopalakrishnan

摘要:

我们考虑的问题,无羡慕蛋糕切割,这是一个连续的异构资源分配之间的自我利益的球员,没有人喜欢别人收到什么,他们得到的。现有的工作集中在两个不同的类的解决方案,这个问题-分配给每个球员一个连续的一块蛋糕和分配给每个球员任意多个不相交的蛋糕。我们的目标是调查这两个极端之间的分配参数化的最大数量的不相交件每个球员可能会收到。我们将不可分割性价格(POI)描述为社会福利(功利主义和平等主义)的收益,从给每个参与者一块连续的蛋糕的分配转移到可能给每个参与者$k$不相交的蛋糕的分配。我们的研究结果包含了功利主义和平等主义社会福利的不可分割性价格的界限,以及无嫉妒切蛋糕和切蛋糕没有任何公平约束。

英文摘要:

We consider the problem of envy-free cake cutting, which is the distribution of a continuous heterogeneous resource among self interested players such that nobody prefers what somebody else receives to what they get. Existing work has focused on two distinct classes of solutions to this problem - allocations which give each player a continuous piece of cake and allocations which give each player arbitrarily many disjoint pieces of cake. Our aim is to investigate allocations between these two extremes by parameterizing the maximum number of disjoint pieces each player may receive. We characterize the Price of Indivisibility (POI) as the gain achieved in social welfare (utilitarian and egalitarian), by moving from allocations which give each player a continuous piece of cake to allocations that may give each player up to $k$ disjoint pieces of cake. Our results contain bounds for the Price of Indivisibility for utilitarian as well as egalitarian social welfare, and for envy-free cake cutting as well as cake cutting without any fairness constraints.
