Another way to elect a variable number of seats is to use Monroe's method. Here's the overview for a fixed number of winners, N. Every voter gives every candidate a score on a numeric scale. Then we find the optimal way to choose the N winners AND divide up the voters equally and assign them to

As far as iterative methods go, I like RRV. It seems to be the natural way to extend the divisor methods to work with range-style inputs. But I feel like the combinatorial methods will give better proportionality than iterative methods. If there are lots of candidates, the best four-winner set

Dear election methods fans, After reading the last few messages on this topic, my feeling is that immunity to burying should be its own criterion. I?m not quite sure what the relationship is to later-no-help and later-no-harm, but it doesn?t seem like it?s quite equivalent to either of
