pau-minoves / jseats Goto Github PK

Hello,

I've stumbled upon your library and I haven't seen any Condorcet methods (http://en.wikipedia.org/wiki/Condorcet_method). Do you see any value on implementing those?

If so, I would implement the most common one(s)

thanks in advance,

Currently ProcessorConfig and Candidate contain contain Properties members that are left to default serialization, which is ugly at best.

Change to something like:

...
<properties>
    <key>value</key>
<properties>
...

We need some test stories here.

Objects like Tally, Candidate and Result should support:

• clone
• append
• add
• substract
• etc

where applicable.

As a separate project, export the API as a REST service and a minimal web application to serve as a seat allocation online calculator.

A walker functionality in processor to allow for interactive execution of methods.

public class Walker {
    public void step(args...) {
        // log, put a message to JMS, go to console to ask user feedback, etc.
    }
}

SeatAllocationProcessor.process(..., walker ,...);

walker.step() gets called in key points of the SeatAllocationMethod implementation.

This would serve both for interactive step-by-step execution of methods and for user injected logging.

We need some stories here.

Implement the TieBreaker interface in a special TieBreakerChain that runs through a list of user provided TieBreakers in a chain-of-responsability fashion.

See: http://en.wikipedia.org/wiki/Mixed-member_proportional_representation

Used in Germany, UK and New Zealand.

Not clear if this can be implemented as a SeatAllocationMethod or a JUnit use case on top of the processor.

This depends on #17

We need some stories here.

Issue for bug on pull request #7

Scenario: Base bug scenario
Given empty scenario
Given tally has candidate CandidateA with 100 votes
Given tally has candidate CandidateB with 100 votes
Given tally has candidate CandidateC with 75 votes
Given tally has candidate CandidateD with 200 votes
Given algorithm has property numberOfSeats set to 1
Given algorithm has property groupSeatsPerCandidate set to true
When process with RankByVotes method
Then result type is TIE
Then result has 2 seats
Then result seat #0 is CandidateA
Then result seat #1 is CandidateB
!-- The tie is below the numberOfSeats threshold. Result should be SINGLE -> CandidateD

Feature from @alvarogarcia7.

There is some code to take on branch bugfix/candidate-order-on-ties.
