Copeland voting: ties matter

We study the complexity of manipulation for a family of election systems derived from Copeland voting via introducing a parameter α that describes how ties in head-to-head contests are valued. We show that the thus obtained problem of manipulation for unweighted Copeland elections is NP-complete even if the size of the manipulating coalition is limited to two. Our result holds for all rational ...

We assume that the outcomes of each game or pairwise vote are jointly independent. In particular, we do not assume that votes arise from voters’ ranked orderings of candidates. We can treat such games as pairwise preferences, without assuming any form of ...
