操纵行为的复杂性,当投票与领带

Complexity of Manipulative Actions When Voting with Ties

Zack Fitzsimmons, Edith Hemaspaandra

摘要:

大多数选举问题的计算研究都假设每个选民的偏好是或应该扩展到全序。然而,在实践中,选民可能对领带有偏好。我们研究的复杂性,选民可以有关系的选举中的操纵行为,扩大选举系统的定义(必要时),以处理选民的关系。我们表明,自然选举系统,允许关系可以增加和减少操纵和贿赂的复杂性,我们国家的控制的复杂性与关系的选民的效果的一般结果。

英文摘要:

Most of the computational study of election problems has assumed that each voter's preferences are, or should be extended to, a total order. However in practice voters may have preferences with ties. We study the complexity of manipulative actions on elections where voters can have ties, extending the definitions of the election systems (when necessary) to handle voters with ties. We show that for natural election systems allowing ties can both increase and decrease the complexity of manipulation and bribery, and we state a general result on the effect of voters with ties on the complexity of control.
