red parts of each ballot - RCV / IRV - how to find programmatically
masiarek last edited by masiarek
I would like to teak an existing Python RCV tabulation program to mark all the rankings (see below in red color) that have been ignored by RCV tabulation process (these are exhausted ballots). I want to be able to demonstrate to RCV folks how quickly and many exhausted ballots/rankings are ignored / discarded.
how to find programmatically:
https://www.rangevoting.org/IrvIgnoreExample.html - "the red parts of each ballot are ignored by the IRV process -
What would be the best algorithm to find the red parts?
I'm fairly sure it's straightforward. Look at the final two candidates, and any candidate ranked below either of them on a voter's ballot is red.
Edit: Also I think that example image is slightly wrong, the ballot that has D > F > B > ... should have B in black.
