Regles positionnelles iteratives, principe majoritaire et preferences unimodales

Sequential scoring rules are multi‐stage social choice tules that work as follows: at each stage of the process, a score is computed for each alternative by taking into account its position in the individual preference rankings, and the alternative with the lowest score is eliminated. The current paper studies the ability of these rules for choosing the Condorcet winner (or the strong Condorcet winner) when individual preferences are single‐peaked.
