Exclusive - Cs50 Tideman

The Tideman method (specifically the Ranked Pairs algorithm) is designed to solve a specific problem: the "Spoiler Effect" and vote splitting. In standard plurality voting, two similar candidates can split the vote, causing a less popular third candidate to win. The Tideman method ensures that if a candidate would beat every other candidate in a head-to-head matchup, that candidate must win. This candidate is known as the .

This feature adds a function that visualizes how the Tideman algorithm resolves tied preferences and locked pairs, making it easier to debug and understand the election process. cs50 tideman
