Vote::Count::Redact
Methods for Redacting Ballots.
Redacting Ballots is useful for what-if analysis and identifying Later Harm effects. Compound Methods seeking to reduce Later Harm effects can also be developed using this technique.
use Vote::Count::Redact qw/RedactPair RedactBullet RedactSingle/;
Takes a list (array) of choices to be converted to bullet votes. Returns a modified BallotSet where all votes that had a first choice vote for a member of the list are votes for only that choice.
my $newBallotSet = RedactBullet( $Election->BallotSet(), 'A', 'B', 'F');
Return a new BallotSet truncating the ballots after the given choice.
my $newBallotSet = RedactSingle( $VoteCountObject->BallotSet(), $choice);
For a Ballot Set and two choices, on each ballot where both appear it removes the later one and all subsequent choices, returning a completely independent new BallotSet. If the later choices were left intact, they would become votes against the redacted choices in those pairings.
my $newBallotSet = RedactPair( $VoteCountObject->BallotSet(), 'A', 'B');
