NAME

Vote::Count::BottomRunOff

VERSION 2.02

Description

Bottom RunOff is an elimination method which takes the two lowest choices, the choice which would lose a runoff is eliminated.

Synopsis

my $eliminate = $Election->BottomRunOff();
# log the pairing result
$Election->logd( $eliminate->{'runoff'} );
# log elimination in the short log too.
$Election->logt( "eliminated ${\ $eliminate->{'eliminate'} }.");
# Perform the elimination
$Election->Defeat( $eliminate->{'eliminate'} );

BottomRunOff

The TieBreakMethod must either be 'precedence' or TieBreakerFallBackPrecedence must be true or BottomRunOff will die. Takes an optional named parameter of an active set.

my $result = $Election->BottomRunOff();
my $result = $Election->BottomRunOff( 'active' => $active );
my $result = $Election->BottomRunOff( 'ranking2' => $othermethod );

Orders the Choices according to Top Count and uses Precedence to resolve any equal rankings. Then conducts a runoff between the two lowest choices in the order.

The returned value is a hashref with the keys: eliminate, continuing, and runoff, runoff describes the totals for the two choices in the runoff.

The optional values are ranking2 and active. See UnTieList in Vote::Count::TieBreaker, the ranking1 passed to it is always TopCount. active is used to provide a hashref to override the current active list.
