稳定婚姻中的贿赂与控制

Bribery and Control in Stable Marriage

Niclas Boehmer, Robert Bredereck, Klaus Heeger, Rolf Niedermeier

摘要:

我们通过考虑几种操纵行为以及几种操纵目标来研究稳定婚姻中的外部操纵。例如,一个目标是确保给定的一对代理在稳定的解决方案中匹配,这可以通过重新排序一些代理的偏好列表的操纵动作来实现。我们提出了一个全面的研究计算复杂性的所有问题,以这种方式。我们发现几个多项式时间可解的情况下,以及NP-难的。对于NP困难的情况,专注于自然参数预算(即允许执行的操纵动作的数量),我们还进行了参数化的复杂性分析,并遇到大多数参数化的硬度结果。

英文摘要:

We initiate the study of external manipulations in Stable Marriage by considering several manipulative actions as well as several manipulation goals. For instance, one goal is to make sure that a given pair of agents is matched in a stable solution, and this may be achieved by the manipulative action of reordering some agents' preference lists. We present a comprehensive study of the computational complexity of all problems arising in this way. We find several polynomial-time solvable cases as well as NP-hard ones. For the NP-hard cases, focusing on the natural parameter budget (that is, the number of manipulative actions one is allowed to perform), we also conduct a parameterized complexity analysis and encounter mostly parameterized hardness results.
