Normalized Range Voting Broadly Resists Control

摘要

We study the behavior of Range Voting and Normalized Range Voting withrespect to electoral control. Electoral control encompasses attempts from anelection chair to alter the structure of an election in order to change theoutcome. We show that a voting system resists a case of control by proving thatperforming that case of control is computationally infeasible. Range Voting isa natural extension of approval voting, and Normalized Range Voting is a simplevariant which alters each vote to maximize the potential impact of each voter.We show that Normalized Range Voting has among the largest number of controlresistances among natural voting systems.
