Majority Judgment for Golang
WORK IN PROGRESS
A Go library to deliberate using Majority Judgment.
We use a score-based algorithm, for performance and scalability.
Supports billions of judgments and thousands of proposals per poll, if need be.
Installation
go get -u github.com/mieuxvoter/judgment
Usage
Say you have the following tally:
You can compute out the majority judgment rank of each proposal like so:
package main
import (
"fmt"
"log"
"github.com/mieuxvoter/judgment"
)
func main() {
poll := &(judgment.PollTally{
AmountOfJudges: 10,
Proposals: []*judgment.ProposalTally{
{Tally: []uint64{2, 2, 2, 2, 2}}, // Proposal A Amount of judgments received for each grade,
{Tally: []uint64{2, 1, 1, 1, 5}}, // Proposal B from "worst" grade to "best" grade.
{Tally: []uint64{2, 1, 1, 2, 4}}, // Proposal C Make sure all tallies are balanced, that is they
{Tally: []uint64{2, 1, 5, 0, 2}}, // Proposal D hold the same total amount of judgments.
{Tally: []uint64{2, 2, 2, 2, 2}}, // Proposal E Equal proposals share the same rank.
// …
},
})
deliberator := &(judgment.MajorityJudgment{})
result, err := deliberator.Deliberate(poll)
if nil != err {
log.Fatalf("Deliberation failed: %v", err)
}
// Proposals results are ordered like tallies, but Rank is available.
// result.Proposals[0].Rank == 4
// result.Proposals[1].Rank == 1
// result.Proposals[2].Rank == 2
// result.Proposals[4].Rank == 3
// result.Proposals[5].Rank == 4
}
