Majority Judgment Library for Java

Test-driven java library to help deliberate using Majority Judgment.

Example Usage

Collect the tallies for each Proposal (aka. Candidate) by your own means, provide them to the MajorityJudgmentDeliberator, and get back the rank of each Proposal.

Let's say you have the following tally:

To Reject Poor Passable Somewhat Good Good Very Good Excellent
Proposal A 4 5 2 1 3 1 2
Proposal B 3 6 2 2 2 1 2
DeliberatorInterface mj = new MajorityJudgmentDeliberator();
TallyInterface tally = new Tally(new ProposalTallyInterface[] {
        // Amounts of judgments received for each grade, from "worst" grade to "best" grade
        new ProposalTally(new Integer[]{4, 5, 2, 1, 3, 1, 2}),  // Proposal A
        new ProposalTally(new Integer[]{3, 6, 2, 1, 3, 1, 2}),  // Proposal B
        // …
});
ResultInterface result = mj.deliberate(tally);

// Each proposal result has a rank, and results are returned by input order
assert(2 == result.getProposalResults().length);
assert(2 == result.getProposalResults()[0].getRank());  // Proposal A
assert(1 == result.getProposalResults()[1].getRank());  // Proposal B
