Compiling the votes of a subelectorate
Yann Chevaleyre, Jérôme Lang, Nicolas Maudet, Guillaume Ravilly-Abadie · 2009
In many practical contexts where a number ofagents have to find a common decision, the votes donot come all together at the same time. In such situations, we may want to preprocess the informationgiven by the subelectorate (consisting of the voterswho have expressed their votes) so as to “compile”the known votes for the time when the latecomershave expressed their votes. We study the amount ofspace necessary for such a compilation, as a function of the voting rule, the number of candidates,and the number of votes already known. We relateour results to existing work, especially on communication complexity.
