Ranked Robin (RCV-RR) — concept pages

Everything explaining Ranked Robin — the same ranked ballot as RCV-IRV, counted a different way: run every candidate head-to-head against every other (a round-robin), and elect the one with the best win-loss record (Copeland). It's a Condorcet / consensus method — when a candidate beats everyone, they win; the interesting question is what happens when nobody does (a cycle).

New here? Start with Ranked Robin (the method).

The method

• Why Ranked Robin — the positive case: the friendly upgrade for ranked ballots (start here for the "why").
• Ranked Robin — the pairwise round-robin and the win-count
• A naming decoder — round-robin / Copeland / Condorcet / Ranked Robin, which word means what
• What should we call this method? — the naming options weighed, pros and cons: the brand, the algorithm, the family, and what each choice costs
• A blank is ranked last — what a blank means, why rank numbers don't matter (it's not Borda), and the universal ballot wording
• Condorcet methods — a reading list — the books and papers behind the decoder, each with its lean marked
• Ranked Robin vs. Consensus Choice — the sibling brand: same count, different cycle rule, different proposal scope
• Summability — the pairwise matrix adds (unlike IRV)
• Clone independence — crowding, teaming, and the tiebreak that matters
• Tiebreaks — LH vs. BetterVoting — a documented engine divergence
• Honest limits

Condorcet & cycles

• Ranked Robin vs. "the Condorcet winner" — same animal, until there's a cycle
• Cycle resolution — why Minimax, Ranked Pairs, and Schulze exist
• The math behind Condorcet — tournaments, the Smith set, and cycles

Worked examples — run them yourself

Every claim on these pages has a runnable election behind it — one case folder per idea:

• The worked intro — RR elects the consensus center 3–0 over the two poles that hold more first choices
• Condorcet vs. Ranked Robin — a clean Condorcet winner, a genuine rock/paper/scissors cycle, and a real 0-wins record
• RR vs. IRV vs. plurality — one ranked ballot set, three different winners (the Tennessee center squeeze)
• The Copeland score — a draw is worth half a win — why "most head-to-head wins" is a shorthand, and the case where the ½-credit decides
• Most matchups won ≠ Condorcet winner — its mirror image: strictly the most wins, and still beaten head-to-head
• Tiebreaks — the Equal Support column and the full ladder down to lot
• Burial — the signature wart, worked as a sincere/buried pair on both engines
• STAR vs RR — 30 divergence samples — where the two methods part ways, each sample stating its own cause
