Center node: "election control with voters uncertainty hardness and approximation results"
  Abstract: The election control problem asks to find a set of nodes in a social network of voters to be the starters of a political campaign aimed at supporting a given target candidate. When a voter is reached by the campaign it changes its opinion on the candidates. The goal is to shape the diffusion of the campaign in such a way that the chances of victory of the target candidate are maximized. #R##N#Previous works on this problem show that it can be approximated within a constant ratio in several models for information diffusion and voting systems. These works assume the full knowledge of the preferences of each voter. However, this information is not always available since voters can be undecided or they may not want to reveal it. Herein we relax this assumption by considering that each voter is associated with a probability distribution over the candidates. #R##N#We propose two new models in which, when a voter is reached by a campaign, it modifies its probability distribution according to the amount of influence it received from its neighbors in the network. We then study the election control problem on the new models: In the first model, under the Gap-ETH hypothesis, election control cannot be approximated within a factor better than $1/n^{o(1)}$, where $n$ is the number of voters; in the second model the problem admits a constant factor approximation algorithm.
