Definitions

Candidate means the name of a person or persons seeking election and listed on the ballot paper(s) to be counted

Continuing Candidate means a candidate that has not been excluded from or declared not-elected in the process of the count

Total Vote (Tv) is the total number of ballot papers that express a valid preference allocated to candidates remaining in the count

Quota )Droop Quota(Q) means the number determined by dividing the Total Vote (Tv) by 1 more than the number of candidates required to be elected and by increasing the quotient (disregarding any remainder) (Q = integer(Tv/(1+No of Vacancies))+1)

or Alternatively a Full Proportional Quota (Q) means the number determined by dividing the Total Vote (Tv) by the number of candidates required to be elected (disregarding any remainder)

Value of the Vote (Vv) means the value allocated to each ballot paper as it progresses though the count.

Candidate’s Total Value of votes (Ctvv) means the aggregated sum of the value of each ballot paper allocated to the candidate.

Surplus Value (Sv) means the value calculated by subtracting the Quota (Q) from the Candidates Total Value’ of votes (Sv = Ctvv-Q)

Surplus Transfer Value (Stv) means the value calculated by the Surplus value (Sv) divided by the Candidate’s Total Value of votes (Ctvv) and then multiplied by the Value of vote (Vv) allocated to each ballot paper ((Stv = Sv/Ctvv)*Vv)

Ballot Paper means a record of a voter’s intention and allocation, in ascending order of preference, of support for a nominated candidate for election. It also refers to a vote which is a record in electronic format representing information and preference allocations of a ballot paper.

Vote means a mathematical representation and record of a ballot paper

Preference means the number in ascending order that represents the order of voter’s preference attributed to a candidate for election as recorded on a ballot paper or data file.

Electronic preference data file means an electronic data file representing the allocation and record of preferences and all votes/ballot papers used in the calculation, distribution and determination of the results of the election.

Remainders represent the fractional part arising from a mathematical division recorded in double precision and are to be retained with and form part of the value of the vote and/or the total value attributed to a candidate

Exhausted Votes means the aggregated value attributed to any votes that do not express a valid preference for a candidate remaining within the count. The ballot paper and it’s attributed value are declared exhausted and a tally of all exhausted votes recorded.

Bulk exclusion means the method of determining the number of candidates which can be simultaneously excluded from the count

Running Sum means the progressive calculation the sum of all candidates total votes from lowest to highest in descending order

Quota Breakpoint means highest running sum value that is less than half of the Quota

Running Breakpoint means the candidate with a total vote value that is greater than the associated running sum of all candidates with a lower total vote.

Applied Breakpoint means the candidate with a highest total vote that is less than the associated running sum of all candidates with a lower total vote and less than the difference between the Quota' and the value of the highest scoring candidate that is below Quota.

Famous quotes containing the word definitions:

    Lord Byron is an exceedingly interesting person, and as such is it not to be regretted that he is a slave to the vilest and most vulgar prejudices, and as mad as the winds?
    There have been many definitions of beauty in art. What is it? Beauty is what the untrained eyes consider abominable.
    Edmond De Goncourt (1822–1896)

    What I do not like about our definitions of genius is that there is in them nothing of the day of judgment, nothing of resounding through eternity and nothing of the footsteps of the Almighty.
    —G.C. (Georg Christoph)

    The loosening, for some people, of rigid role definitions for men and women has shown that dads can be great at calming babies—if they take the time and make the effort to learn how. It’s that time and effort that not only teaches the dad how to calm the babies, but also turns him into a parent, just as the time and effort the mother puts into the babies turns her into a parent.
    Pamela Patrick Novotny (20th century)
