Kemeny–Ktour

The Kemeny–Young method is a way to find the most fair overall ranking from multiple people's preferences. Imagine several voters rank options (like candidates or products). This method searches for a single order that best aligns with all the individual rankings, minimizing disagreements. It finds the ranking that has the highest total agreement with everyone’s preferences, providing a consensus decision that balances differing opinions. While computationally complex for large sets, it offers a fair and democratic way to combine multiple rankings into one collective order.
