      Short pitch. Can SPAV be improved by making some kind of hybrid with Sequential SAV/E&E cumulative? These are showers thoughts and I am out of my league, so be nice.

      According to my wikipedia education, one of the issues with SPAV compared to PAV is that it is a 'greedy algorithm' that only looks at the most locally optimal solution.
      Now SAV considers the whole field at once but doesn't fix under and over votes.
      Sequential SAV Does deal with undervoting at least, but still looks at the whole field of seats and remaining candidates per round, rather than just seat by seat like SPAV. Different, but is it meaningfully so?
      My brain wonders, could we hybridize these to get more accurate results while still being simpler than PAV?
      Has anyone tried to do that before that I could take a look at?

        @matthewmvp By SAV, do you mean Satisfaction Approval Voting? It's a poor method. Like PAV but just worse. I'm not sure how it could be combined to make an improved method. What's E&E cumulative?

          AFAIK Sequential SAV and Sequential PAV are the same procedure, which is actually the trick I use to explain SPAV more intuitively: I describe SAV, then explaining how SPAV fixes the spoiler effect in SAV.

          Did you read the SAV Wiki article in the past week or two? I tried explaining this way of thinking about SAV in the article to make it simpler, but might have unintentionally made it more confusing instead of less.
