and my understanding is that Schulze, RP, and Minmax all elect the same
candidate for case of a simple 3-choice cycle and, of course, they all
elect the same candidate when there is no cycle. so, then wouldn't
simplicity of description be the only salient difference, at least from
a POV of the public?
