Manipulative agendas in four-candidate elections

We consider a setting where it is known for an electorate what probability a given candidate has of beating another in a pairwise ballot. An agenda assigns candidates to the leaves of a binary tree and is called manipulative if it inverts the final winning probabilities for two candidates. We compar...
