控制日期顺序选举的复杂性

The Complexity of Controlling Candidate-Sequential Elections

Edith Hemaspaandra, Lane A. Hemaspaandra, Joerg Rothe

摘要:

候选人对选举的控制是研究增加或删除候选人如何影响选举结果。然而,传统的候选人控制的复杂性的研究是在模型中,所有的候选人和选票是已知的。本文提出了一个模型,用于研究在线控制的选举结构是顺序的候选人,并在其中的决定,增加和删除必须在候选人提出的那一刻。我们表明,很大的复杂性-PSPACE完备性-可以发生在这种情况下,但我们也提供了在这种情况下的多项式时间算法的最重要的选举系统,多元化。

英文摘要:

Candidate control of elections is the study of how adding or removing candidates can affect the outcome. However, the traditional study of the complexity of candidate control is in the model in which all candidates and votes are known up front. This paper develops a model for studying online control for elections where the structure is sequential with respect to the candidates, and in which the decision regarding adding and deleting must be irrevocably made at the moment the candidate is presented. We show that great complexity---PSPACE-completeness---can occur in this setting, but we also provide within this setting polynomial-time algorithms for the most important of election systems, plurality.
