One silly method is to use Range Voting except instead of summing the "utilities", they are multiplied instead. This results in: A: 100^55 * 0^45 = 0 B: 100^45 * 0^55 = 0 C: 80^100 However, this similar to Veto Voting! I had thought of this before as it is a way of determining "consensus." What would be nice if there were a mathematical operator that is mixture of addition and multiplication. Or may be some other method to tone down the harshness of multiplication. As a compromise, what I thought of doing was to slowly increase the minimum utilities of each ballot (possibly re-normalising the C utilities while this happens) until two candidates get (equal) top scores. The two candidates then go to the second round of voting. However, doing this in this scenario, it is inevitable that candidates A and C will go to the second round...
