Strengthening Full Justified Representation: Efficient Verification and Computation
TL;DR
FJR+ is a new, efficiently verifiable enhancement of the full justified representation (FJR) for approval-based committee elections. It allows for polynomial-time verification and satisfaction, improving the feasibility of implementing fair election rules.
✦ Why It Matters
Consider implementing FJR+ in your next approval-based election to enhance fairness and efficiency.
Key Takeaways
- Explore FJR+ for efficient verification in committee elections.
- Utilize the RBG algorithm for selecting partial committees.
- Implement sequential Phragmén for priceable outcomes.
- Adapt FJR+ for participatory budgeting with variable project costs.
How It Works
FJR+ enhances the existing FJR framework by allowing for polynomial-time verification and satisfaction. The RBG algorithm selects a partial committee, ensuring that any completion of size $k$ meets the FJR+ criteria.
This approach leverages the flexibility of sequential Phragmén to achieve priceable outcomes, which are essential for fair election processes.
