Independence of Smith-dominated alternatives

Independence of Smith-dominated alternatives (ISDA, also known as Smith-IIA) is a voting system criterion which says that the winner of an election should not be affected by candidates who are not in the Smith set. Another way of defining ISDA is to say that adding a new candidate should not change the winner of an election, unless that new candidate would beat the original winner, either directly or indirectly.
