In this paper, we propose a new single-winner voting system using ranked ballots: Stable Voting. The motivating principle of Stable Voting is that if a candidate A would win without another candidate B in the election, and A beats B in a head-to-head majority comparison, then A should still win in the election with B included (unless there is another candidate A' who has the same kind of claim to winning, in which case a tiebreaker may choose between A and A'). We call this principle Stability for Winners (with Tiebreaking). Stable Voting satisfies this principle while also having a remarkable ability to avoid tied outcomes in elections even with small numbers of voters.

稳定投票

在本文中，我们提出了一种使用排名选票的新的单一获胜者投票系统：稳定投票。稳定投票的激励原则是，如果候选人 A 在没有另一个候选人 B 的情况下在选举中获胜，并且 A 在面对面的多数比较中击败了 B，那么 A 仍然应该在包含 B 的选举中获胜（除非有是另一个候选人 A'，他有同样的获胜要求，在这种情况下，决胜局可以在 A 和 A' 之间进行选择）。我们将此原则称为获胜者的稳定性（与决胜局）。稳定投票满足了这一原则，同时也具有显着的能力，即使在少数选民的情况下也能避免选举中的结果不一致。
