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?
