RANKING OF CANDIDATES IN VOTING SYSTEMS BASED ON VIRTUAL CANDIDATES

A key issue in the preferential voting framework is how voters express their preferences on a set of candidates. There are different methods to allow the voters to state their preferences on a set of candidates. The main drawback of such scoring rules is that they assume the votes of all voters have equal importance and there is no preference among them. To the best of our knowledge, till now there is no method to obtain the preference score of candidates in which there exist a priority among voters. Then we introduce two models to measure the best preference scores of the target candidate from the virtual best candidate and the virtual worst candidate point of view. Finally, we aggregate the two preference scores together for an overall ranking.
